* fix(ui): show all session logs in the drawer, not just the first 50 (#29795)

* fix(ui): show newest session logs first

* test(ui): keep session log pagination coverage

* fix(ui): show all session logs in the drawer, not just the first page

The session detail drawer fetched session logs via sessionSpendLogsCall
without page/page_size, so it only ever received the backend default of one
page (50 rows). Sessions with more than 50 calls had the rest unreachable in
the UI (#29153).

sessionSpendLogsCall now takes page/page_size, and the drawer fetches the
first page, reads total_pages, then fetches the remaining pages and
accumulates them before the existing client-side sort. This keeps the single
continuous list (and the selected-log lookup and keyboard navigation, which
all assume the full session) correct. Fetching is bounded by a page cap, and
the sidebar shows a "showing most recent N" note if a session exceeds it.

The rows are lightweight metadata (the endpoint excludes messages/response),
so the full set is small; request/response bodies are still loaded per log on
demand.

* fix(ui): default session drawer to most recent log, newest first

Open a session with its most recent log selected, and order the sidebar
newest-first to match the all-sessions logs overview. MCP calls stay
grouped last. The latest log by time is computed explicitly, since the
MCP grouping means it is not always the first row.

* fix(ui): derive session total from accumulated rows when backend omits it

Compute the session total after all pages are fetched, falling back to the
accumulated row count rather than the first page's. Guards the truncation
note against a backend response that omits total but spans multiple pages.

* fix(vertex_ai): use REP host for context caching on eu/us multi-region endpoints (#29573)

Context caching built the cachedContents URL as
https://{location}-aiplatform.googleapis.com, which is an invalid host for the
eu/us multi-region endpoints and returns 404. The inference path already
resolves these to the REP host (https://aiplatform.{geo}.rep.googleapis.com)
via get_vertex_base_url(); reuse that helper in
_get_token_and_url_context_caching so caching uses the same host as inference.

Adds tests covering the eu/us multi-region cachedContents URLs (v1 and
v1beta1).

* fix: propagate upstream status code in proxy API exception handler

When Google GenAI / Vertex returns a 404 for deprecated or missing
models via streamGenerateContent, the exception was falling through to
a generic handler that defaulted to 500. Now provider exceptions
carrying a valid HTTP status_code correctly propagate it through to
the ProxyException.

* fix: tighten status code range to 400-599 and deduplicate ProxyException raise

* fix(tests): use valid vertex_location in context caching tests

Replace "test_location" (contains underscore) with "us-central1" so tests
pass the regex validation added in get_vertex_base_url().

* fix(proxy) #27734 allow clearing budget_duration and team_member fields by sending null on /key/update and /team/update (#27751)

* fix(proxy): allow clearing budget_duration and team_member fields by sending null on /key/update and /team/update

Fixes #27734

Sending null for budget_duration, team_member_budget,
team_member_budget_duration, team_member_rpm_limit, or
team_member_tpm_limit via /key/update or /team/update returned 200 OK
but silently ignored the null value. The fields remained unchanged in
the database.

Root causes:
- /key/update: prepare_key_update_data() popped budget_duration from the
  update dict but never re-added it (or budget_reset_at) when the value
  was None.
- /team/update: _set_budget_reset_at() only acted when budget_duration
  was non-None, leaving a stale budget_reset_at in the DB.
- /team/update: team_member_* null values bypassed the budget table
  update entirely because should_create_budget() requires at least one
  non-None field.

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes (#30028)

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes

When output_parse_pii=true on the Anthropic native path (anthropic/claude-*),
response chunks arrive as raw bytes in SSE format. _stream_pii_unmasking was
yielding those bytes unchanged, so <PERSON_1> tokens were never replaced with
the original values before reaching the caller.

Add _unmask_sse_bytes_chunk to parse each data: line, find content_block_delta
/ text_delta events, and apply _unmask_pii_text before re-encoding. Wire it
into _stream_pii_unmasking so bytes chunks are unmasked when pii_tokens exist.

* fix(presidio): handle CRLF line endings and non-ASCII PII in SSE unmask

Strip trailing \r before the [DONE] guard so CRLF-terminated SSE chunks
don't bypass it and silently swallow a JSONDecodeError. Add
ensure_ascii=False to json.dumps so non-ASCII replacement values like
accented names are preserved as UTF-8 on the wire rather than being
\uXXXX-escaped. Add regression tests for both cases.

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses) (#29925)

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses)

Bedrock Mantle serves the Responses API on two upstream paths:
  - gpt frontier models (gpt-5.5 / gpt-5.4) on /openai/v1/responses
  - every other Responses-capable model (e.g. gpt-oss) on the standard /v1/responses

BedrockMantleResponsesAPIConfig gains a `use_openai_path` flag; the provider gate in
utils.py picks the path per model: openai.gpt-* (non gpt-oss) -> /openai/v1/responses;
any model declared mode=responses (price-map entry or user model_info) -> /v1/responses;
everything else returns None and keeps the existing chat-completions emulation.

Adds gpt-5.5 / gpt-5.4 price-map entries, registry wiring, and the routing-matrix tests.

* feat(bedrock_mantle): data-driven frontier routing via use_openai_responses_path

Addresses the Greptile review point that frontier detection should be a
price-map field rather than a hardcoded name match. The gate now routes a
model to /openai/v1/responses when its price-map entry declares
use_openai_responses_path, so a frontier model whose name does not follow the
openai.gpt- convention can be onboarded by JSON alone. The name-convention
check is kept as a fallback that needs no price-map entry, which preserves
zero-change routing for a future gpt-6 before its entry loads. gpt-5.5 / gpt-5.4
get the flag in both price maps. Adds tests for the data-driven flag path and
for the flag presence on the gpt-5.x entries; both branches are mutation-tested.

* test(model_prices): allow use_openai_responses_path in price-map schema

The model_prices_and_context_window.json schema validator
(test_aaamodel_prices_and_context_window_json_is_valid) enforces
additionalProperties: false, so the new use_openai_responses_path flag on the
gpt-5.5 / gpt-5.4 entries failed validation. Add it to the schema as a boolean,
alongside the other supports_* / capability flags.

* fix(proxy): use Responses-API transformer in pass-through cost tracking (#29728)

The `elif is_responses:` branch of `openai_passthrough_handler` was
calling the chat-completions `transform_response` on a Responses API
payload. The chat-completions transformer expects `choices: [...]`
in the raw response; the Responses API uses `output: [...]` and
`usage.input_tokens` / `usage.output_tokens` (not
`prompt_tokens` / `completion_tokens`). The result was a
KeyError 'choices' deep inside `convert_to_model_response_object`,
swallowed by the surrounding `except Exception` in the handler, and
the SpendLogs row was written by the fallback path with zeroed-out
tokens, spend, and model.

This bug silently undercounts cost for every successful pass-through
call to either OpenAI's `/v1/responses` or Azure's
`/openai/v1/responses` (deployments configured for the Responses
API). Reproduced 2026-06-04 against a real Azure OpenAI Responses
API deployment proxied through LiteLLM v1.88.0.

Fix: use the dedicated
`OpenAIResponsesAPIConfig.transform_response_api_response` for the
Responses branch. This transformer already exists in LiteLLM
(`litellm/llms/openai/responses/transformation.py`) and knows the
Responses-API on-the-wire shape. `litellm.completion_cost` already
handles `ResponsesAPIResponse` natively with `call_type="responses"`,
so no downstream changes are needed.

Tests:

  test_responses_api_uses_responses_transformer_not_chat_completions
    NEW. Real regression test — exercises the openai_passthrough_handler
    with a real-shaped Responses payload (no `choices`, has `output`
    and Responses-API `usage` keys) and NO mocked `get_provider_config`.
    Pre-fix: raises KeyError 'choices' inside the chat-completions
    transformer (the bug). Post-fix: returns a ResponsesAPIResponse,
    completion_cost is called with call_type="responses" and a
    ResponsesAPIResponse instance (asserted).
    Verified to fail on un-fixed handler + pass on fixed handler
    before commit.

  test_responses_api_cost_tracking
    UPDATED. Old test mocked `get_provider_config` (no longer called
    in the responses branch post-fix). Now mocks the Responses
    transformer directly (`OpenAIResponsesAPIConfig.transform_response_api_response`)
    to test the downstream cost-calc contract.

    OpenAI hostname) in the is_openai_*_route checks. Separate PR.

Skill IDs are generated as litellm_skill_<uuid> and the model-facing

* fix(anthropic): synthesize content_block_start when Responses stream omits output_item.added (#30115)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

models-and-endpoints, organizations, and virtual-keys each had a page.tsx
route under (dashboard)/ that is not in MIGRATED_PAGES, so the sidebar and
deep links never resolve to it and the route is unreachable. Each was a thin
wrapper that handed the shared view empty or no-op props (empty modelData with
a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

This continues the dead-scaffolding cleanup from #28891. The shared components
these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,
since the legacy ?page= switch in app/page.tsx and src/components still import
them

Admins can now suppress the survey and Claude Code feedback popups for

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with

the flag resolves. Falls back to showing nudges if the fetch errors.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

The model map validation schema uses additionalProperties: false, so the

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(anthropic): avoid index -1 content_block_delta in messages stream

When a /v1/messages request is routed through the Responses API
adapter, AnthropicResponsesStreamWrapper only emits content_block_start
on response.output_item.added. Some upstreams (LMStudio for example)
never send that event, so the text delta handler fell back to
_current_block_index, which starts at -1, and clients received
content_block_delta events with index -1 and no preceding
content_block_start. Anthropic SDKs then fail with "text part -1 not
found"

The text delta handler now synthesizes a content_block_start with a
fresh block index whenever the delta references an unregistered item_id
or no block is open yet, and registers the item_id so follow-up deltas
reuse the same index

Addresses the /v1/messages defect in #27442

* Make test sys.path shim resolve relative to the file, not the CWD

os.path.abspath("../../../../../../..") depends on where pytest is
invoked from; anchoring on os.path.dirname(__file__) makes the import
work from any working directory. Also corrects the depth: the repo root
is six levels above this file, not seven.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider (#30114)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

* test: mock post_call_response_headers_hook in audio speech route tests

* chore(ui): remove dead App Router route stubs under (dashboard) (#30045)

models-and-endpoints, organizations, and virtual-keys each had a page.tsx
route under (dashboard)/ that is not in MIGRATED_PAGES, so the sidebar and
deep links never resolve to it and the route is unreachable. Each was a thin
wrapper that handed the shared view empty or no-op props (empty modelData with
a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

This continues the dead-scaffolding cleanup from #28891. The shared components
these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,
since the legacy ?page= switch in app/page.tsx and src/components still import
them

* docs(security): require a reproduction video for vulnerability reports (#30048) (#30063)

With AI models capable of automated vulnerability discovery now publicly
available, we expect a large increase in report volume, much of it
unverified. Requiring a video of the exploit running against a live
instance raises the bar for submissions and keeps triage focused on
reproducible issues. Reports without a video will be closed and reopened
if one is added later.

* feat(ui): add admin flag to disable in-product UI nudges for everyone (#29796)

* feat(ui): add admin flag to disable in-product UI nudges for everyone

Admins can now suppress the survey and Claude Code feedback popups for
all users via a single disable_ui_nudges UI setting, instead of relying
on each user dismissing them individually.

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with
disable_ui_nudges on doesn't see the survey prompt flash, and the
getInProductNudgesCall fetch doesn't fire, on a cold page load before
the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

page.tsx now calls useUISettings (react-query), which needs a
QueryClient that layout.tsx supplies in production but the test did
not. Add the provider and mock getUiSettings so the query resolves.

* chore(ui): remove dead dashboard files and unused dependencies (#30047)

* chore(ui): remove dead dashboard files and unused dependencies

knip flagged seven orphaned source/config files with no importers and
five declared dependencies that nothing in the tree uses. Removing them
shrinks the dashboard bundle's source surface and keeps the manifest
honest; vite stays installed transitively via vitest, so test tooling is
unaffected.

* fix(ci): restore serverRootPath.config.ts referenced by SERVER_ROOT_PATH workflow

The dead-code sweep removed e2e_tests/serverRootPath.config.ts, but its spec
(tests/login/serverRootPathRedirect.spec.ts) and the test_server_root_path.yml
workflow step still depend on it, so the redirect e2e job failed to load a
config that no longer existed.

* fix(proxy): authorize batch files using upload target_model_names (LIT-3593) (#30009)

* fix(proxy): authorize batch files using upload target_model_names (LIT-3593)

After replace_model_in_jsonl, body.model is a stripped provider id. Reverse-mapping it via resolve_model_name_from_model_id is first-match on model_list and caused false 403s when multiple deployments share the same stripped name. Use target_model_names from the unified file id instead.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the
new flag must be declared for the 28 entries that carry it; this was the
one failing job (misc / Run tests) on the previous commit.

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider

The vertex_ai block in anthropic_beta_headers_config.json mapped
compact-2026-01-12 to null, so update_headers_with_filtered_beta
stripped the header before the request reached Vertex while the
compact_20260112 context edit stayed in the body, and Vertex rejected
the request with HTTP 400. Vertex rawPredict accepts the header, and
the bedrock and databricks blocks already forward it. Mirrors #21867,
which enabled context-1m-2025-08-07 for vertex_ai the same way.

Fixes #27290.

sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(proxy): coerce litellm_settings.max_budget env var to float

When max_budget is set in litellm_settings via os.environ/MAX_BUDGET,
the env var resolves to a string and the generic setattr branch in
ProxyConfig.load_config stored it as-is, so the startup check
litellm.max_budget > 0 raised TypeError. The earlier fix (#23855) only
covered the CLI initialize() path. Coerce the value to float in the
settings loop, matching the existing max_internal_user_budget handling.

Fixes #26696.

* fix(router): don't drop bedrock pass-through deployments using IAM credentials (#30111)

* Fix Bedrock passthrough deployment dropped when using IAM credentials

Bedrock deployments with use_in_pass_through enabled and IAM/OIDC auth
(aws_role_name, no api_key) hit the generic pass-through branch in
Router._initialize_deployment_for_pass_through, which calls
set_pass_through_credentials and raises "api_key is required". The
exception drops the deployment from the router entirely, breaking both
passthrough and normal routing for that model.

Skip the credential store write when no api_key is set; the bedrock
passthrough route resolves AWS credentials at request time via
BedrockConverseLLM.get_credentials(), not the passthrough credential
store, so there is nothing to register here.

Fixes #27728.

* Reset passthrough credentials singleton before api_key credential test

The test reads the module-level passthrough_endpoint_router singleton,
so a stale "openai" entry written by an earlier test in the same
process could make the assertion pass without exercising the code path.
Clearing the credentials dict up front makes the test order-independent.

* fix(sdk): stop mirroring reasoning_content in provider_specific_fields (#30110)

The dict-to-response conversion path mirrored reasoning_content into
provider_specific_fields, while live provider transforms (Anthropic's
_build_provider_specific_fields) only set it top-level on the Message.
Cache-replayed messages therefore serialized differently from live
ones, breaking disk cache key stability for multi-turn conversations
with extended thinking.

The mirror was added for DeepSeek before Message.reasoning_content
existed as a top-level attribute. The top-level field is still set by
the converter, so DeepSeek's request-side promotion is unaffected.

Fixes #27337.

* fix(mcp): coerce mcp_server_cost_info values to float at ingest (#30109)

* fix(mcp): coerce mcp_server_cost_info values to float at ingest

YAML 1.1 parses scientific notation without a decimal point
(e.g. 7e-05) as a string, and MCPServerCostInfo is a TypedDict with no
runtime validation, so a string-typed default_cost_per_query from
config.yaml flowed through the proxy untouched and crashed the MCP
server settings page with '.toFixed is not a function'. Normalize
mcp_server_cost_info on both the config and DB load paths, dropping
non-numeric values with a warning instead of failing the server load.

Fixes #27097.

* fix(mcp): drop non-numeric default_cost_per_query instead of nulling it

Keeping the key with a None value still exposes a null to the UI,
which can crash .toFixed formatting when the consumer checks key
existence rather than truthiness. Delete the key on coercion failure,
matching how non-numeric per-tool cost entries are already omitted.

* fix(proxy): count embedding and text completion tokens toward TPM limits (#30105)

* fix(proxy): count embedding and text completion tokens toward TPM limits

The parallel request limiters only read token usage off ModelResponse,
so EmbeddingResponse and TextCompletionResponse objects left
total_tokens at 0 and the per key, user, team, and end user TPM
counters never incremented. Requests to /v1/embeddings and
/v1/completions were effectively free against any tpm_limit. In the v3
limiter this was worse: the post-call reconciliation computed actual
usage as 0 and refunded the pre-call reservation made at request time.

Broaden the isinstance checks to accept EmbeddingResponse and
TextCompletionResponse, which both expose a Usage object, at the four
per-scope sites in parallel_request_limiter.py and at the usage
extraction in parallel_request_limiter_v3.py. ResponsesAPIResponse was
already covered in v3 via BaseLiteLLMOpenAIResponseObject.

Fixes #27738.

* test(proxy): cover v1 limiter TPM counting for embedding and text completion responses

Exercise the broadened isinstance sites in parallel_request_limiter.py
by asserting that async_log_success_event adds total_tokens to the per
key, user, team, and end user TPM counters for EmbeddingResponse and
TextCompletionResponse objects. The counters are pre-seeded at zero so
the assertion is exactly the increment; on the pre-fix code these
responses left total_tokens at 0 and the test fails.

* fix(openai): forward client headers on the text completion path (#30103)

* fix(openai): forward client headers on the text completion path

litellm.completion() merges caller headers with extra_headers, but the
text-completion-openai branch never passed the merged dict to
openai_text_completions.completion(), and the handler only used its
headers argument for logging. Pass the merged headers through the call
site and set them as extra_headers on the outgoing request, mirroring
the chat completion handler, so x-* client headers forwarded by the
proxy reach the provider on /v1/completions.

Fixes #27410.

* Drop redundant extra_headers assignment and fix test module collision

completion() merges extra_headers into headers before the
text-completion-openai branch, and the handler now sets the merged
headers as extra_headers on the request, so the branch-local
optional_params["extra_headers"] assignment was a dead duplicate.
Removing it keeps the assignment in one place while both entry paths
(litellm.text_completion and direct handler callers) still forward
headers; a new regression test pins the extra_headers kwarg path.

Also rename the test module to test_completion_handler.py since its
basename collided with tests/test_litellm/llms/bedrock/batches/
test_handler.py and broke pytest collection.

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel and base64-encode the body (#30102)

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel

POST /v1/messages/count_tokens with Anthropic content blocks
({"type": "text"|"tool_use"|...}) was routed to the Converse input of
the Bedrock CountTokens API. The Converse transform copies list content
through verbatim, so Bedrock rejected the request with a 400 and the
caller silently fell back to the local tokenizer, returning counts that
can be off by ~50% on tool-heavy payloads.

_detect_input_type now routes messages whose content blocks carry a
"type" key (Anthropic shape) to the invokeModel input, which forwards
the body verbatim. The invokeModel body is now base64-encoded as the
CountTokens API requires (InvokeModelTokensRequest.body is a
base64-encoded blob), and Anthropic Messages bodies get the
anthropic_version and max_tokens fields Bedrock validates against.

Fixes #27632.

* fix(ui): show newest session logs first

* test(ui): keep session log pagination coverage

* fix(ui): show all session logs in the drawer, not just the first page

The session detail drawer fetched session logs via sessionSpendLogsCall
without page/page_size, so it only ever received the backend default of one
page (50 rows). Sessions with more than 50 calls had the rest unreachable in
the UI (#29153).

sessionSpendLogsCall now takes page/page_size, and the drawer fetches the
first page, reads total_pages, then fetches the remaining pages and
accumulates them before the existing client-side sort. This keeps the single
continuous list (and the selected-log lookup and keyboard navigation, which
all assume the full session) correct. Fetching is bounded by a page cap, and
the sidebar shows a "showing most recent N" note if a session exceeds it.

The rows are lightweight metadata (the endpoint excludes messages/response),
so the full set is small; request/response bodies are still loaded per log on
demand.

* fix(ui): default session drawer to most recent log, newest first

Open a session with its most recent log selected, and order the sidebar
newest-first to match the all-sessions logs overview. MCP calls stay
grouped last. The latest log by time is computed explicitly, since the
MCP grouping means it is not always the first row.

Context caching built the cachedContents URL as
https://{location}-aiplatform.googleapis.com, which is an invalid host for the
eu/us multi-region endpoints and returns 404. The inference path already
resolves these to the REP host (https://aiplatform.{geo}.rep.googleapis.com)
via get_vertex_base_url(); reuse that helper in
_get_token_and_url_context_caching so caching uses the same host as inference.

Adds tests covering the eu/us multi-region cachedContents URLs (v1 and

* fix(proxy): allow clearing budget_duration and team_member fields by sending null on /key/update and /team/update

Fixes #27734

Sending null for budget_duration, team_member_budget,
team_member_budget_duration, team_member_rpm_limit, or
team_member_tpm_limit via /key/update or /team/update returned 200 OK
but silently ignored the null value. The fields remained unchanged in
the database.

Root causes:
- /key/update: prepare_key_update_data() popped budget_duration from the
  update dict but never re-added it (or budget_reset_at) when the value
  was None.
- /team/update: _set_budget_reset_at() only acted when budget_duration
  was non-None, leaving a stale budget_reset_at in the DB.
- /team/update: team_member_* null values bypassed the budget table
  update entirely because should_create_budget() requires at least one
  non-None field.

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes (#30028)

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes

When output_parse_pii=true on the Anthropic native path (anthropic/claude-*),
response chunks arrive as raw bytes in SSE format. _stream_pii_unmasking was
yielding those bytes unchanged, so <PERSON_1> tokens were never replaced with
the original values before reaching the caller.

Add _unmask_sse_bytes_chunk to parse each data: line, find content_block_delta
/ text_delta events, and apply _unmask_pii_text before re-encoding. Wire it
into _stream_pii_unmasking so bytes chunks are unmasked when pii_tokens exist.

* fix(presidio): handle CRLF line endings and non-ASCII PII in SSE unmask

Strip trailing \r before the [DONE] guard so CRLF-terminated SSE chunks
don't bypass it and silently swallow a JSONDecodeError. Add
ensure_ascii=False to json.dumps so non-ASCII replacement values like
accented names are preserved as UTF-8 on the wire rather than being
\uXXXX-escaped. Add regression tests for both cases.

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses) (#29925)

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses)

Bedrock Mantle serves the Responses API on two upstream paths:
  - gpt frontier models (gpt-5.5 / gpt-5.4) on /openai/v1/responses
  - every other Responses-capable model (e.g. gpt-oss) on the standard /v1/responses

BedrockMantleResponsesAPIConfig gains a `use_openai_path` flag; the provider gate in
utils.py picks the path per model: openai.gpt-* (non gpt-oss) -> /openai/v1/responses;
any model declared mode=responses (price-map entry or user model_info) -> /v1/responses;
everything else returns None and keeps the existing chat-completions emulation.

Adds gpt-5.5 / gpt-5.4 price-map entries, registry wiring, and the routing-matrix tests.

* feat(bedrock_mantle): data-driven frontier routing via use_openai_responses_path

Addresses the Greptile review point that frontier detection should be a
price-map field rather than a hardcoded name match. The gate now routes a
model to /openai/v1/responses when its price-map entry declares
use_openai_responses_path, so a frontier model whose name does not follow the
openai.gpt- convention can be onboarded by JSON alone. The name-convention
check is kept as a fallback that needs no price-map entry, which preserves
zero-change routing for a future gpt-6 before its entry loads. gpt-5.5 / gpt-5.4
get the flag in both price maps. Adds tests for the data-driven flag path and
for the flag presence on the gpt-5.x entries; both branches are mutation-tested.

* test(model_prices): allow use_openai_responses_path in price-map schema

The model_prices_and_context_window.json schema validator
(test_aaamodel_prices_and_context_window_json_is_valid) enforces
additionalProperties: false, so the new use_openai_responses_path flag on the
gpt-5.5 / gpt-5.4 entries failed validation. Add it to the schema as a boolean,
alongside the other supports_* / capability flags.

* fix(proxy): use Responses-API transformer in pass-through cost tracking (#29728)

The `elif is_responses:` branch of `openai_passthrough_handler` was
calling the chat-completions `transform_response` on a Responses API
payload. The chat-completions transformer expects `choices: [...]`
in the raw response; the Responses API uses `output: [...]` and
`usage.input_tokens` / `usage.output_tokens` (not
`prompt_tokens` / `completion_tokens`). The result was a
KeyError 'choices' deep inside `convert_to_model_response_object`,
swallowed by the surrounding `except Exception` in the handler, and
the SpendLogs row was written by the fallback path with zeroed-out
tokens, spend, and model.

This bug silently undercounts cost for every successful pass-through
call to either OpenAI's `/v1/responses` or Azure's
`/openai/v1/responses` (deployments configured for the Responses
API). Reproduced 2026-06-04 against a real Azure OpenAI Responses
API deployment proxied through LiteLLM v1.88.0.

Fix: use the dedicated
`OpenAIResponsesAPIConfig.transform_response_api_response` for the
Responses branch. This transformer already exists in LiteLLM
(`litellm/llms/openai/responses/transformation.py`) and knows the
Responses-API on-the-wire shape. `litellm.completion_cost` already
handles `ResponsesAPIResponse` natively with `call_type="responses"`,
so no downstream changes are needed.

Tests:

  test_responses_api_uses_responses_transformer_not_chat_completions
    NEW. Real regression test — exercises the openai_passthrough_handler
    with a real-shaped Responses payload (no `choices`, has `output`
    and Responses-API `usage` keys) and NO mocked `get_provider_config`.
    Pre-fix: raises KeyError 'choices' inside the chat-completions
    transformer (the bug). Post-fix: returns a ResponsesAPIResponse,
    completion_cost is called with call_type="responses" and a
    ResponsesAPIResponse instance (asserted).
    Verified to fail on un-fixed handler + pass on fixed handler
    before commit.

  test_responses_api_cost_tracking
    UPDATED. Old test mocked `get_provider_config` (no longer called
    in the responses branch post-fix). Now mocks the Responses
    transformer directly (`OpenAIResponsesAPIConfig.transform_response_api_response`)
    to test the downstream cost-calc contract.

* fix(anthropic): synthesize content_block_start when Responses stream omits output_item.added (#30115)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

* chore(ui): remove dead dashboard files and unused dependencies

knip flagged seven orphaned source/config files with no importers and
five declared dependencies that nothing in the tree uses. Removing them
shrinks the dashboard bundle's source surface and keeps the manifest
honest; vite stays installed transitively via vitest, so test tooling is
unaffected.

The dead-code sweep removed e2e_tests/serverRootPath.config.ts, but its spec
(tests/login/serverRootPathRedirect.spec.ts) and the test_server_root_path.yml
workflow step still depend on it, so the redirect e2e job failed to load a
config that no longer existed.

After replace_model_in_jsonl, body.model is a stripped provider id. Reverse-mapping it via resolve_model_name_from_model_id is first-match on model_list and caused false 403s when multiple deployments share the same stripped name. Use target_model_names from the unified file id instead.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the
new flag must be declared for the 28 entries that carry it; this was the
one failing job (misc / Run tests) on the previous commit.

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(anthropic): avoid index -1 content_block_delta in messages stream

When a /v1/messages request is routed through the Responses API
adapter, AnthropicResponsesStreamWrapper only emits content_block_start
on response.output_item.added. Some upstreams (LMStudio for example)
never send that event, so the text delta handler fell back to
_current_block_index, which starts at -1, and clients received
content_block_delta events with index -1 and no preceding
content_block_start. Anthropic SDKs then fail with "text part -1 not
found"

The text delta handler now synthesizes a content_block_start with a
fresh block index whenever the delta references an unregistered item_id
or no block is open yet, and registers the item_id so follow-up deltas
reuse the same index

Addresses the /v1/messages defect in #27442

* Make test sys.path shim resolve relative to the file, not the CWD

os.path.abspath("../../../../../../..") depends on where pytest is
invoked from; anchoring on os.path.dirname(__file__) makes the import
work from any working directory. Also corrects the depth: the repo root
is six levels above this file, not seven.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider (#30114)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

models-and-endpoints, organizations, and virtual-keys each had a page.tsx

setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

With AI models capable of automated vulnerability discovery now publicly

instance raises the bar for submissions and keeps triage focused on
reproducible issues. Reports without a video will be closed and reopened
if one is added later.

* feat(ui): add admin flag to disable in-product UI nudges for everyone

Gate nudgesDisabled on the ui-settings loading state so an admin with

the flag resolves. Falls back to showing nudges if the fetch errors.

the bedrock and databricks blocks already forward it. Mirrors #21867,

unverified. Requiring a video of the exploit running against a live
instance raises the bar for submissions and keeps triage focused on
reproducible issues. Reports without a video will be closed and reopened
if one is added later.

* feat(ui): add admin flag to disable in-product UI nudges for everyone (#29796)

* feat(ui): add admin flag to disable in-product UI nudges for everyone

Admins can now suppress the survey and Claude Code feedback popups for
all users via a single disable_ui_nudges UI setting, instead of relying
on each user dismissing them individually.

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with
disable_ui_nudges on doesn't see the survey prompt flash, and the
getInProductNudgesCall fetch doesn't fire, on a cold page load before
the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

page.tsx now calls useUISettings (react-query), which needs a

not. Add the provider and mock getUiSettings so the query resolves.

knip flagged seven orphaned source/config files with no importers and

shrinks the dashboard bundle's source surface and keeps the manifest
honest; vite stays installed transitively via vitest, so test tooling is
unaffected.

* fix(ci): restore serverRootPath.config.ts referenced by SERVER_ROOT_PATH workflow

The dead-code sweep removed e2e_tests/serverRootPath.config.ts, but its spec

workflow step still depend on it, so the redirect e2e job failed to load a
config that no longer existed.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the
new flag must be declared for the 28 entries that carry it; this was the
one failing job (misc / Run tests) on the previous commit.

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(proxy): coerce litellm_settings.max_budget env var to float

When max_budget is set in litellm_settings via os.environ/MAX_BUDGET,
the env var resolves to a string and the generic setattr branch in
ProxyConfig.load_config stored it as-is, so the startup check
litellm.max_budget > 0 raised TypeError. The earlier fix (#23855) only
covered the CLI initialize() path. Coerce the value to float in the
settings loop, matching the existing max_internal_user_budget handling.

* fix(router): don't drop bedrock pass-through deployments using IAM credentials (#30111)

* Fix Bedrock passthrough deployment dropped when using IAM credentials

Bedrock deployments with use_in_pass_through enabled and IAM/OIDC auth
(aws_role_name, no api_key) hit the generic pass-through branch in
Router._initialize_deployment_for_pass_through, which calls
set_pass_through_credentials and raises "api_key is required". The
exception drops the deployment from the router entirely, breaking both
passthrough and normal routing for that model.

Skip the credential store write when no api_key is set; the bedrock
passthrough route resolves AWS credentials at request time via
BedrockConverseLLM.get_credentials(), not the passthrough credential
store, so there is nothing to register here.

Fixes #27728.

* Reset passthrough credentials singleton before api_key credential test

The test reads the module-level passthrough_endpoint_router singleton,
so a stale "openai" entry written by an earlier test in the same
process could make the assertion pass without exercising the code path.
Clearing the credentials dict up front makes the test order-independent.

* fix(sdk): stop mirroring reasoning_content in provider_specific_fields (#30110)

The dict-to-response conversion path mirrored reasoning_content into
provider_specific_fields, while live provider transforms (Anthropic's
_build_provider_specific_fields) only set it top-level on the Message.
Cache-replayed messages therefore serialized differently from live
ones, breaking disk cache key stability for multi-turn conversations
with extended thinking.

The mirror was added for DeepSeek before Message.reasoning_content
existed as a top-level attribute. The top-level field is still set by
the converter, so DeepSeek's request-side promotion is unaffected.

Fixes #27337.

* fix(mcp): coerce mcp_server_cost_info values to float at ingest (#30109)

* fix(mcp): coerce mcp_server_cost_info values to float at ingest

YAML 1.1 parses scientific notation without a decimal point
(e.g. 7e-05) as a string, and MCPServerCostInfo is a TypedDict with no
runtime validation, so a string-typed default_cost_per_query from
config.yaml flowed through the proxy untouched and crashed the MCP
server settings page with '.toFixed is not a function'. Normalize
mcp_server_cost_info on both the config and DB load paths, dropping
non-numeric values with a warning instead of failing the server load.

Fixes #27097.

* fix(mcp): drop non-numeric default_cost_per_query instead of nulling it

Keeping the key with a None value still exposes a null to the UI,
which can crash .toFixed formatting when the consumer checks key
existence rather than truthiness. Delete the key on coercion failure,
matching how non-numeric per-tool cost entries are already omitted.

* fix(proxy): count embedding and text completion tokens toward TPM limits (#30105)

* fix(proxy): count embedding and text completion tokens toward TPM limits

The parallel request limiters only read token usage off ModelResponse,
so EmbeddingResponse and TextCompletionResponse objects left
total_tokens at 0 and the per key, user, team, and end user TPM
counters never incremented. Requests to /v1/embeddings and
/v1/completions were effectively free against any tpm_limit. In the v3
limiter this was worse: the post-call reconciliation computed actual
usage as 0 and refunded the pre-call reservation made at request time.

Broaden the isinstance checks to accept EmbeddingResponse and
TextCompletionResponse, which both expose a Usage object, at the four
per-scope sites in parallel_request_limiter.py and at the usage
extraction in parallel_request_limiter_v3.py. ResponsesAPIResponse was
already covered in v3 via BaseLiteLLMOpenAIResponseObject.

Fixes #27738.

* test(proxy): cover v1 limiter TPM counting for embedding and text completion responses

Exercise the broadened isinstance sites in parallel_request_limiter.py
by asserting that async_log_success_event adds total_tokens to the per
key, user, team, and end user TPM counters for EmbeddingResponse and
TextCompletionResponse objects. The counters are pre-seeded at zero so
the assertion is exactly the increment; on the pre-fix code these
responses left total_tokens at 0 and the test fails.

* fix(openai): forward client headers on the text completion path (#30103)

* fix(openai): forward client headers on the text completion path

litellm.completion() merges caller headers with extra_headers, but the
text-completion-openai branch never passed the merged dict to
openai_text_completions.completion(), and the handler only used its
headers argument for logging. Pass the merged headers through the call
site and set them as extra_headers on the outgoing request, mirroring
the chat completion handler, so x-* client headers forwarded by the
proxy reach the provider on /v1/completions.

Fixes #27410.

* Drop redundant extra_headers assignment and fix test module collision

completion() merges extra_headers into headers before the
text-completion-openai branch, and the handler now sets the merged
headers as extra_headers on the request, so the branch-local
optional_params["extra_headers"] assignment was a dead duplicate.
Removing it keeps the assignment in one place while both entry paths
(litellm.text_completion and direct handler callers) still forward
headers; a new regression test pins the extra_headers kwarg path.

Also rename the test module to test_completion_handler.py since its
basename collided with tests/test_litellm/llms/bedrock/batches/
test_handler.py and broke pytest collection.

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel and base64-encode the body (#30102)

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel

POST /v1/messages/count_tokens with Anthropic content blocks
({"type": "text"|"tool_use"|...}) was routed to the Converse input of
the Bedrock CountTokens API. The Converse transform copies list content
through verbatim, so Bedrock rejected the request with a 400 and the
caller silently fell back to the local tokenizer, returning counts that
can be off by ~50% on tool-heavy payloads.

_detect_input_type now routes messages whose content blocks carry a
"type" key (Anthropic shape) to the invokeModel input, which forwards
the body verbatim. The invokeModel body is now base64-encoded as the
CountTokens API requires (InvokeModelTokensRequest.body is a
base64-encoded blob), and Anthropic Messages bodies get the
anthropic_version and max_tokens fields Bedrock validates against.

Fixes #27632.

* fix(ui): show all session logs in the drawer, not just the first 50 (#29795)

* fix(ui): show newest session logs first

* test(ui): keep session log pagination coverage

* fix(ui): show all session logs in the drawer, not just the first page

The session detail drawer fetched session logs via sessionSpendLogsCall
without page/page_size, so it only ever received the backend default of one
page (50 rows). Sessions with more than 50 calls had the rest unreachable in
the UI (#29153).

sessionSpendLogsCall now takes page/page_size, and the drawer fetches the
first page, reads total_pages, then fetches the remaining pages and
accumulates them before the existing client-side sort. This keeps the single
continuous list (and the selected-log lookup and keyboard navigation, which
all assume the full session) correct. Fetching is bounded by a page cap, and
the sidebar shows a "showing most recent N" note if a session exceeds it.

The rows are lightweight metadata (the endpoint excludes messages/response),
so the full set is small; request/response bodies are still loaded per log on
demand.

* fix(ui): default session drawer to most recent log, newest first

Open a session with its most recent log selected, and order the sidebar
newest-first to match the all-sessions logs overview. MCP calls stay
grouped last. The latest log by time is computed explicitly, since the
MCP grouping means it is not always the first row.

Context caching built the cachedContents URL as
https://{location}-aiplatform.googleapis.com, which is an invalid host for the
eu/us multi-region endpoints and returns 404. The inference path already
resolves these to the REP host (https://aiplatform.{geo}.rep.googleapis.com)
via get_vertex_base_url(); reuse that helper in
_get_token_and_url_context_caching so caching uses the same host as inference.

Adds tests covering the eu/us multi-region cachedContents URLs (v1 and

* fix(proxy): allow clearing budget_duration and team_member fields by sending null on /key/update and /team/update

Fixes #27734

Sending null for budget_duration, team_member_budget,
team_member_budget_duration, team_member_rpm_limit, or
team_member_tpm_limit via /key/update or /team/update returned 200 OK
but silently ignored the null value. The fields remained unchanged in
the database.

Root causes:
- /key/update: prepare_key_update_data() popped budget_duration from the
  update dict but never re-added it (or budget_reset_at) when the value
  was None.
- /team/update: _set_budget_reset_at() only acted when budget_duration
  was non-None, leaving a stale budget_reset_at in the DB.
- /team/update: team_member_* null values bypassed the budget table
  update entirely because should_create_budget() requires at least one
  non-None field.

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes (#30028)

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes

When output_parse_pii=true on the Anthropic native path (anthropic/claude-*),
response chunks arrive as raw bytes in SSE format. _stream_pii_unmasking was
yielding those bytes unchanged, so <PERSON_1> tokens were never replaced with
the original values before reaching the caller.

Add _unmask_sse_bytes_chunk to parse each data: line, find content_block_delta
/ text_delta events, and apply _unmask_pii_text before re-encoding. Wire it
into _stream_pii_unmasking so bytes chunks are unmasked when pii_tokens exist.

* fix(presidio): handle CRLF line endings and non-ASCII PII in SSE unmask

Strip trailing \r before the [DONE] guard so CRLF-terminated SSE chunks
don't bypass it and silently swallow a JSONDecodeError. Add
ensure_ascii=False to json.dumps so non-ASCII replacement values like
accented names are preserved as UTF-8 on the wire rather than being
\uXXXX-escaped. Add regression tests for both cases.

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses)

Bedrock Mantle serves the Responses API on two upstream paths:
  - gpt frontier models (gpt-5.5 / gpt-5.4) on /openai/v1/responses
  - every other Responses-capable model (e.g. gpt-oss) on the standard /v1/responses

BedrockMantleResponsesAPIConfig gains a `use_openai_path` flag; the provider gate in
utils.py picks the path per model: openai.gpt-* (non gpt-oss) -> /openai/v1/responses;
any model declared mode=responses (price-map entry or user model_info) -> /v1/responses;
everything else returns None and keeps the existing chat-completions emulation.

Adds gpt-5.5 / gpt-5.4 price-map entries, registry wiring, and the routing-matrix tests.

* feat(bedrock_mantle): data-driven frontier routing via use_openai_responses_path

Addresses the Greptile review point that frontier detection should be a
price-map field rather than a hardcoded name match. The gate now routes a
model to /openai/v1/responses when its price-map entry declares
use_openai_responses_path, so a frontier model whose name does not follow the
openai.gpt- convention can be onboarded by JSON alone. The name-convention
check is kept as a fallback that needs no price-map entry, which preserves
zero-change routing for a future gpt-6 before its entry loads. gpt-5.5 / gpt-5.4
get the flag in both price maps. Adds tests for the data-driven flag path and
for the flag presence on the gpt-5.x entries; both branches are mutation-tested.

* test(model_prices): allow use_openai_responses_path in price-map schema

The model_prices_and_context_window.json schema validator
(test_aaamodel_prices_and_context_window_json_is_valid) enforces
additionalProperties: false, so the new use_openai_responses_path flag on the
gpt-5.5 / gpt-5.4 entries failed validation. Add it to the schema as a boolean,
alongside the other supports_* / capability flags.

* fix(proxy): use Responses-API transformer in pass-through cost tracking (#29728)

The `elif is_responses:` branch of `openai_passthrough_handler` was
calling the chat-completions `transform_response` on a Responses API
payload. The chat-completions transformer expects `choices: [...]`
in the raw response; the Responses API uses `output: [...]` and
`usage.input_tokens` / `usage.output_tokens` (not
`prompt_tokens` / `completion_tokens`). The result was a
KeyError 'choices' deep inside `convert_to_model_response_object`,
swallowed by the surrounding `except Exception` in the handler, and
the SpendLogs row was written by the fallback path with zeroed-out
tokens, spend, and model.

This bug silently undercounts cost for every successful pass-through
call to either OpenAI's `/v1/responses` or Azure's
`/openai/v1/responses` (deployments configured for the Responses
API). Reproduced 2026-06-04 against a real Azure OpenAI Responses
API deployment proxied through LiteLLM v1.88.0.

Fix: use the dedicated
`OpenAIResponsesAPIConfig.transform_response_api_response` for the
Responses branch. This transformer already exists in LiteLLM
(`litellm/llms/openai/responses/transformation.py`) and knows the
Responses-API on-the-wire shape. `litellm.completion_cost` already
handles `ResponsesAPIResponse` natively with `call_type="responses"`,
so no downstream changes are needed.

Tests:

  test_responses_api_uses_responses_transformer_not_chat_completions
    NEW. Real regression test — exercises the openai_passthrough_handler
    with a real-shaped Responses payload (no `choices`, has `output`
    and Responses-API `usage` keys) and NO mocked `get_provider_config`.
    Pre-fix: raises KeyError 'choices' inside the chat-completions
    transformer (the bug). Post-fix: returns a ResponsesAPIResponse,
    completion_cost is called with call_type="responses" and a
    ResponsesAPIResponse instance (asserted).
    Verified to fail on un-fixed handler + pass on fixed handler
    before commit.

  test_responses_api_cost_tracking
    UPDATED. Old test mocked `get_provider_config` (no longer called
    in the responses branch post-fix). Now mocks the Responses
    transformer directly (`OpenAIResponsesAPIConfig.transform_response_api_response`)
    to test the downstream cost-calc contract.

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

* chore(ui): remove dead App Router route stubs under (dashboard) (#30045)

models-and-endpoints, organizations, and virtual-keys each had a page.tsx
route under (dashboard)/ that is not in MIGRATED_PAGES, so the sidebar and
deep links never resolve to it and the route is unreachable. Each was a thin
wrapper that handed the shared view empty or no-op props (empty modelData with
a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

This continues the dead-scaffolding cleanup from #28891. The shared components
these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,
since the legacy ?page= switch in app/page.tsx and src/components still import
them

* feat(ui): add admin flag to disable in-product UI nudges for everyone

Admins can now suppress the survey and Claude Code feedback popups for
all users via a single disable_ui_nudges UI setting, instead of relying
on each user dismissing them individually.

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with
disable_ui_nudges on doesn't see the survey prompt flash, and the
getInProductNudgesCall fetch doesn't fire, on a cold page load before
the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

page.tsx now calls useUISettings (react-query), which needs a
QueryClient that layout.tsx supplies in production but the test did
not. Add the provider and mock getUiSettings so the query resolves.

* chore(ui): remove dead dashboard files and unused dependencies

knip flagged seven orphaned source/config files with no importers and

shrinks the dashboard bundle's source surface and keeps the manifest
honest; vite stays installed transitively via vitest, so test tooling is
unaffected.

* fix(ci): restore serverRootPath.config.ts referenced by SERVER_ROOT_PATH workflow

The dead-code sweep removed e2e_tests/serverRootPath.config.ts, but its spec
(tests/login/serverRootPathRedirect.spec.ts) and the test_server_root_path.yml
workflow step still depend on it, so the redirect e2e job failed to load a

After replace_model_in_jsonl, body.model is a stripped provider id. Reverse-mapping it via resolve_model_name_from_model_id is first-match on model_list and caused false 403s when multiple deployments share the same stripped name. Use target_model_names from the unified file id instead.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the
new flag must be declared for the 28 entries that carry it; this was the
one failing job (misc / Run tests) on the previous commit.

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(anthropic): avoid index -1 content_block_delta in messages stream

When a /v1/messages request is routed through the Responses API
adapter, AnthropicResponsesStreamWrapper only emits content_block_start
on response.output_item.added. Some upstreams (LMStudio for example)
never send that event, so the text delta handler fell back to
_current_block_index, which starts at -1, and clients received
content_block_delta events with index -1 and no preceding
content_block_start. Anthropic SDKs then fail with "text part -1 not
found"

The text delta handler now synthesizes a content_block_start with a
fresh block index whenever the delta references an unregistered item_id
or no block is open yet, and registers the item_id so follow-up deltas
reuse the same index

Addresses the /v1/messages defect in #27442

* Make test sys.path shim resolve relative to the file, not the CWD

os.path.abspath("../../../../../../..") depends on where pytest is
invoked from; anchoring on os.path.dirname(__file__) makes the import
work from any working directory. Also corrects the depth: the repo root
is six levels above this file, not seven.

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider

The vertex_ai block in anthropic_beta_headers_config.json mapped
compact-2026-01-12 to null, so update_headers_with_filtered_beta
stripped the header before the request reached Vertex while the
compact_20260112 context edit stayed in the body, and Vertex rejected
the request with HTTP 400. Vertex rawPredict accepts the header, and
the bedrock and databricks blocks already forward it. Mirrors #21867,
which enabled context-1m-2025-08-07 for vertex_ai the same way.

Fixes #27290.

* fix(proxy): coerce litellm_settings.max_budget env var to float (#30113)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

* chore(ui): remove dead App Router route stubs under (dashboard) (#30045)

models-and-endpoints, organizations, and virtual-keys each had a page.tsx
route under (dashboard)/ that is not in MIGRATED_PAGES, so the sidebar and
deep links never resolve to it and the route is unreachable. Each was a thin
wrapper that handed the shared view empty or no-op props (empty modelData with
a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

This continues the dead-scaffolding cleanup from #28891. The shared components
these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,
since the legacy ?page= switch in app/page.tsx and src/components still import
them

instance raises the bar for submissions and keeps triage focused on
reproducible issues. Reports without a video will be closed and reopened
if one is added later.

* feat(ui): add admin flag to disable in-product UI nudges for everyone

Admins can now suppress the survey and Claude Code feedback popups for
all users via a single disable_ui_nudges UI setting, instead of relying
on each user dismissing them individually.

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with
disable_ui_nudges on doesn't see the survey prompt flash, and the
getInProductNudgesCall fetch doesn't fire, on a cold page load before
the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

page.tsx now calls useUISettings (react-query), which needs a
QueryClient that layout.tsx supplies in production but the test did
not. Add the provider and mock getUiSettings so the query resolves.

unaffected.

The dead-code sweep removed e2e_tests/serverRootPath.config.ts, but its spec

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

* fix(proxy): coerce litellm_settings.max_budget env var to float

When max_budget is set in litellm_settings via os.environ/MAX_BUDGET,
the env var resolves to a string and the generic setattr branch in

litellm.max_budget > 0 raised TypeError. The earlier fix (#23855) only
covered the CLI initialize() path. Coerce the value to float in the
settings loop, matching the existing max_internal_user_budget handling.

* fix(router): don't drop bedrock pass-through deployments using IAM credentials (#30111)

* Fix Bedrock passthrough deployment dropped when using IAM credentials

Bedrock deployments with use_in_pass_through enabled and IAM/OIDC auth
(aws_role_name, no api_key) hit the generic pass-through branch in
Router._initialize_deployment_for_pass_through, which calls
set_pass_through_credentials and raises "api_key is required". The
exception drops the deployment from the router entirely, breaking both
passthrough and normal routing for that model.

Skip the credential store write when no api_key is set; the bedrock
passthrough route resolves AWS credentials at request time via
BedrockConverseLLM.get_credentials(), not the passthrough credential
store, so there is nothing to register here.

Fixes #27728.

* Reset passthrough credentials singleton before api_key credential test

The test reads the module-level passthrough_endpoint_router singleton,
so a stale "openai" entry written by an earlier test in the same
process could make the assertion pass without exercising the code path.
Clearing the credentials dict up front makes the test order-independent.

* fix(sdk): stop mirroring reasoning_content in provider_specific_fields (#30110)

The dict-to-response conversion path mirrored reasoning_content into
provider_specific_fields, while live provider transforms (Anthropic's
_build_provider_specific_fields) only set it top-level on the Message.
Cache-replayed messages therefore serialized differently from live
ones, breaking disk cache key stability for multi-turn conversations
with extended thinking.

The mirror was added for DeepSeek before Message.reasoning_content
existed as a top-level attribute. The top-level field is still set by
the converter, so DeepSeek's request-side promotion is unaffected.

Fixes #27337.

* fix(mcp): coerce mcp_server_cost_info values to float at ingest (#30109)

* fix(mcp): coerce mcp_server_cost_info values to float at ingest

YAML 1.1 parses scientific notation without a decimal point
(e.g. 7e-05) as a string, and MCPServerCostInfo is a TypedDict with no
runtime validation, so a string-typed default_cost_per_query from
config.yaml flowed through the proxy untouched and crashed the MCP
server settings page with '.toFixed is not a function'. Normalize
mcp_server_cost_info on both the config and DB load paths, dropping
non-numeric values with a warning instead of failing the server load.

Fixes #27097.

* fix(mcp): drop non-numeric default_cost_per_query instead of nulling it

Keeping the key with a None value still exposes a null to the UI,
which can crash .toFixed formatting when the consumer checks key
existence rather than truthiness. Delete the key on coercion failure,
matching how non-numeric per-tool cost entries are already omitted.

* fix(proxy): count embedding and text completion tokens toward TPM limits (#30105)

* fix(proxy): count embedding and text completion tokens toward TPM limits

The parallel request limiters only read token usage off ModelResponse,
so EmbeddingResponse and TextCompletionResponse objects left
total_tokens at 0 and the per key, user, team, and end user TPM
counters never incremented. Requests to /v1/embeddings and
/v1/completions were effectively free against any tpm_limit. In the v3
limiter this was worse: the post-call reconciliation computed actual
usage as 0 and refunded the pre-call reservation made at request time.

Broaden the isinstance checks to accept EmbeddingResponse and
TextCompletionResponse, which both expose a Usage object, at the four
per-scope sites in parallel_request_limiter.py and at the usage
extraction in parallel_request_limiter_v3.py. ResponsesAPIResponse was
already covered in v3 via BaseLiteLLMOpenAIResponseObject.

Fixes #27738.

* test(proxy): cover v1 limiter TPM counting for embedding and text completion responses

Exercise the broadened isinstance sites in parallel_request_limiter.py
by asserting that async_log_success_event adds total_tokens to the per
key, user, team, and end user TPM counters for EmbeddingResponse and
TextCompletionResponse objects. The counters are pre-seeded at zero so
the assertion is exactly the increment; on the pre-fix code these
responses left total_tokens at 0 and the test fails.

* fix(openai): forward client headers on the text completion path (#30103)

* fix(openai): forward client headers on the text completion path

litellm.completion() merges caller headers with extra_headers, but the
text-completion-openai branch never passed the merged dict to
openai_text_completions.completion(), and the handler only used its
headers argument for logging. Pass the merged headers through the call
site and set them as extra_headers on the outgoing request, mirroring
the chat completion handler, so x-* client headers forwarded by the
proxy reach the provider on /v1/completions.

Fixes #27410.

* Drop redundant extra_headers assignment and fix test module collision

completion() merges extra_headers into headers before the
text-completion-openai branch, and the handler now sets the merged
headers as extra_headers on the request, so the branch-local
optional_params["extra_headers"] assignment was a dead duplicate.
Removing it keeps the assignment in one place while both entry paths
(litellm.text_completion and direct handler callers) still forward
headers; a new regression test pins the extra_headers kwarg path.

Also rename the test module to test_completion_handler.py since its
basename collided with tests/test_litellm/llms/bedrock/batches/
test_handler.py and broke pytest collection.

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel and base64-encode the body (#30102)

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel

POST /v1/messages/count_tokens with Anthropic content blocks
({"type": "text"|"tool_use"|...}) was routed to the Converse input of
the Bedrock CountTokens API. The Converse transform copies list content
through verbatim, so Bedrock rejected the request with a 400 and the
caller silently fell back to the local tokenizer, returning counts that
can be off by ~50% on tool-heavy payloads.

_detect_input_type now routes messages whose content blocks carry a
"type" key (Anthropic shape) to the invokeModel input, which forwards
the body verbatim. The invokeModel body is now base64-encoded as the
CountTokens API requires (InvokeModelTokensRequest.body is a
base64-encoded blob), and Anthropic Messages bodies get the
anthropic_version and max_tokens fields Bedrock validates against.

Fixes #27632.

* fix(ui): show newest session logs first

* test(ui): keep session log pagination coverage

* fix(ui): show all session logs in the drawer, not just the first page

The session detail drawer fetched session logs via sessionSpendLogsCall
without page/page_size, so it only ever received the backend default of one
page (50 rows). Sessions with more than 50 calls had the rest unreachable in
the UI (#29153).

sessionSpendLogsCall now takes page/page_size, and the drawer fetches the
first page, reads total_pages, then fetches the remaining pages and
accumulates them before the existing client-side sort. This keeps the single
continuous list (and the selected-log lookup and keyboard navigation, which
all assume the full session) correct. Fetching is bounded by a page cap, and
the sidebar shows a "showing most recent N" note if a session exceeds it.

The rows are lightweight metadata (the endpoint excludes messages/response),
so the full set is small; request/response bodies are still loaded per log on
demand.

* fix(ui): default session drawer to most recent log, newest first

Open a session with its most recent log selected, and order the sidebar
newest-first to match the all-sessions logs overview. MCP calls stay
grouped last. The latest log by time is computed explicitly, since the
MCP grouping means it is not always the first row.

Context caching built the cachedContents URL as

eu/us multi-region endpoints and returns 404. The inference path already
resolves these to the REP host (https://aiplatform.{geo}.rep.googleapis.com)
via get_vertex_base_url(); reuse that helper in
_get_token_and_url_context_caching so caching uses the same host as inference.

team_member_tpm_limit via /key/update or /team/update returned 200 OK
but silently ignored the null value. The fields remained unchanged in
the database.

Root causes:
- /key/update: prepare_key_update_data() popped budget_duration from the
  update dict but never re-added it (or budget_reset_at) when the value
  was None.
- /team/update: _set_budget_reset_at() only acted when budget_duration
  was non-None, leaving a stale budget_reset_at in the DB.
- /team/update: team_member_* null values bypassed the budget table
  update entirely because should_create_budget() requires at least one
  non-None field.

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes (#30028)

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes

When output_parse_pii=true on the Anthropic native path (anthropic/claude-*),
response chunks arrive as raw bytes in SSE format. _stream_pii_unmasking was
yielding those bytes unchanged, so <PERSON_1> tokens were never replaced with
the original values before reaching the caller.

Add _unmask_sse_bytes_chunk to parse each data: line, find content_block_delta
/ text_delta events, and apply _unmask_pii_text before re-encoding. Wire it
into _stream_pii_unmasking so bytes chunks are unmasked when pii_tokens exist.

* fix(presidio): handle CRLF line endings and non-ASCII PII in SSE unmask

Strip trailing \r before the [DONE] guard so CRLF-terminated SSE chunks
don't bypass it and silently swallow a JSONDecodeError. Add
ensure_ascii=False to json.dumps so non-ASCII replacement values like
accented names are preserved as UTF-8 on the wire rather than being
\uXXXX-escaped. Add regression tests for both cases.

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses) (#29925)

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses)

Bedrock Mantle serves the Responses API on two upstream paths:
  - gpt frontier models (gpt-5.5 / gpt-5.4) on /openai/v1/responses
  - every other Responses-capable model (e.g. gpt-oss) on the standard /v1/responses

BedrockMantleResponsesAPIConfig gains a `use_openai_path` flag; the provider gate in
utils.py picks the path per model: openai.gpt-* (non gpt-oss) -> /openai/v1/responses;
any model declared mode=responses (price-map entry or user model_info) -> /v1/responses;
everything else returns None and keeps the existing chat-completions emulation.

Adds gpt-5.5 / gpt-5.4 price-map entries, registry wiring, and the routing-matrix tests.

* feat(bedrock_mantle): data-driven frontier routing via use_openai_responses_path

Addresses the Greptile review point that frontier detection should be a
price-map field rather than a hardcoded name match. The gate now routes a
model to /openai/v1/responses when its price-map entry declares
use_openai_responses_path, so a frontier model whose name does not follow the
openai.gpt- convention can be onboarded by JSON alone. The name-convention
check is kept as a fallback that needs no price-map entry, which preserves
zero-change routing for a future gpt-6 before its entry loads. gpt-5.5 / gpt-5.4
get the flag in both price maps. Adds tests for the data-driven flag path and
for the flag presence on the gpt-5.x entries; both branches are mutation-tested.

* test(model_prices): allow use_openai_responses_path in price-map schema

The model_prices_and_context_window.json schema validator
(test_aaamodel_prices_and_context_window_json_is_valid) enforces
additionalProperties: false, so the new use_openai_responses_path flag on the
gpt-5.5 / gpt-5.4 entries failed validation. Add it to the schema as a boolean,
alongside the other supports_* / capability flags.

* fix(proxy): use Responses-API transformer in pass-through cost tracking (#29728)

The `elif is_responses:` branch of `openai_passthrough_handler` was
calling the chat-completions `transform_response` on a Responses API
payload. The chat-completions transformer expects `choices: [...]`
in the raw response; the Responses API uses `output: [...]` and
`usage.input_tokens` / `usage.output_tokens` (not
`prompt_tokens` / `completion_tokens`). The result was a
KeyError 'choices' deep inside `convert_to_model_response_object`,
swallowed by the surrounding `except Exception` in the handler, and
the SpendLogs row was written by the fallback path with zeroed-out
tokens, spend, and model.

This bug silently undercounts cost for every successful pass-through
call to either OpenAI's `/v1/responses` or Azure's
`/openai/v1/responses` (deployments configured for the Responses
API). Reproduced 2026-06-04 against a real Azure OpenAI Responses
API deployment proxied through LiteLLM v1.88.0.

Fix: use the dedicated
`OpenAIResponsesAPIConfig.transform_response_api_response` for the
Responses branch. This transformer already exists in LiteLLM
(`litellm/llms/openai/responses/transformation.py`) and knows the
Responses-API on-the-wire shape. `litellm.completion_cost` already
handles `ResponsesAPIResponse` natively with `call_type="responses"`,
so no downstream changes are needed.

Tests:

  test_responses_api_uses_responses_transformer_not_chat_completions
    NEW. Real regression test — exercises the openai_passthrough_handler
    with a real-shaped Responses payload (no `choices`, has `output`
    and Responses-API `usage` keys) and NO mocked `get_provider_config`.
    Pre-fix: raises KeyError 'choices' inside the chat-completions
    transformer (the bug). Post-fix: returns a ResponsesAPIResponse,
    completion_cost is called with call_type="responses" and a
    ResponsesAPIResponse instance (asserted).
    Verified to fail on un-fixed handler + pass on fixed handler
    before commit.

  test_responses_api_cost_tracking
    UPDATED. Old test mocked `get_provider_config` (no longer called
    in the responses branch post-fix). Now mocks the Responses
    transformer directly (`OpenAIResponsesAPIConfig.transform_response_api_response`)
    to test the downstream cost-calc contract.

    OpenAI hostname) in the is_openai_*_route checks. Separate PR.

Skill IDs are generated as litellm_skill_<uuid> and the model-facing

in SkillsInjectionHook only ran tools whose name starts with "skill_",
so DB skills were silently returned to the client as raw tool calls.

* fix(anthropic): synthesize content_block_start when Responses stream omits output_item.added (#30115)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team

clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run

Both are no-ops by default, so CI behavior is unchanged.

e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

models-and-endpoints, organizations, and virtual-keys each had a page.tsx

a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

This continues the dead-scaffolding cleanup from #28891. The shared components
these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,

Admins can now suppress the survey and Claude Code feedback popups for

* fix(ui): suppress nudges while ui settings are loading

Gate nudgesDisabled on the ui-settings loading state so an admin with

the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(anthropic): avoid index -1 content_block_delta in messages stream

When a /v1/messages request is routed through the Responses API
adapter, AnthropicResponsesStreamWrapper only emits content_block_start
on response.output_item.added. Some upstreams (LMStudio for example)
never send that event, so the text delta handler fell back to
_current_block_index, which starts at -1, and clients received
content_block_delta events with index -1 and no preceding
content_block_start. Anthropic SDKs then fail with "text part -1 not
found"

The text delta handler now synthesizes a content_block_start with a
fresh block index whenever the delta references an unregistered item_id
or no block is open yet, and registers the item_id so follow-up deltas
reuse the same index

Addresses the /v1/messages defect in #27442

* Make test sys.path shim resolve relative to the file, not the CWD

os.path.abspath("../../../../../../..") depends on where pytest is
invoked from; anchoring on os.path.dirname(__file__) makes the import
work from any working directory. Also corrects the depth: the repo root
is six levels above this file, not seven.

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

Truthiness check let top_k=0 silently disappear on models that removed

set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider

The vertex_ai block in anthropic_beta_headers_config.json mapped
compact-2026-01-12 to null, so update_headers_with_filtered_beta
stripped the header before the request reached Vertex while the
compact_20260112 context edit stayed in the body, and Vertex rejected
the request with HTTP 400. Vertex rawPredict accepts the header, and
the bedrock and databricks blocks already forward it. Mirrors #21867,
which enabled context-1m-2025-08-07 for vertex_ai the same way.

Fixes #27290.

* fix(proxy): coerce litellm_settings.max_budget env var to float (#30113)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

* fix(router): don't drop bedrock pass-through deployments using IAM credentials (#30111)

* Fix Bedrock passthrough deployment dropped when using IAM credentials

Bedrock deployments with use_in_pass_through enabled and IAM/OIDC auth
(aws_role_name, no api_key) hit the generic pass-through branch in
Router._initialize_deployment_for_pass_through, which calls
set_pass_through_credentials and raises "api_key is required". The
exception drops the deployment from the router entirely, breaking both
passthrough and normal routing for that model.

Skip the credential store write when no api_key is set; the bedrock
passthrough route resolves AWS credentials at request time via
BedrockConverseLLM.get_credentials(), not the passthrough credential
store, so there is nothing to register here.

Fixes #27728.

* Reset passthrough credentials singleton before api_key credential test

The test reads the module-level passthrough_endpoint_router singleton,
so a stale "openai" entry written by an earlier test in the same
process could make the assertion pass without exercising the code path.
Clearing the credentials dict up front makes the test order-independent.

* fix(sdk): stop mirroring reasoning_content in provider_specific_fields (#30110)

The dict-to-response conversion path mirrored reasoning_content into
provider_specific_fields, while live provider transforms (Anthropic's
_build_provider_specific_fields) only set it top-level on the Message.
Cache-replayed messages therefore serialized differently from live
ones, breaking disk cache key stability for multi-turn conversations
with extended thinking.

The mirror was added for DeepSeek before Message.reasoning_content
existed as a top-level attribute. The top-level field is still set by
the converter, so DeepSeek's request-side promotion is unaffected.

Fixes #27337.

* fix(mcp): coerce mcp_server_cost_info values to float at ingest (#30109)

* fix(mcp): coerce mcp_server_cost_info values to float at ingest

YAML 1.1 parses scientific notation without a decimal point
(e.g. 7e-05) as a string, and MCPServerCostInfo is a TypedDict with no
runtime validation, so a string-typed default_cost_per_query from
config.yaml flowed through the proxy untouched and crashed the MCP
server settings page with '.toFixed is not a function'. Normalize
mcp_server_cost_info on both the config and DB load paths, dropping
non-numeric values with a warning instead of failing the server load.

Fixes #27097.

* fix(mcp): drop non-numeric default_cost_per_query instead of nulling it

Keeping the key with a None value still exposes a null to the UI,
which can crash .toFixed formatting when the consumer checks key
existence rather than truthiness. Delete the key on coercion failure,
matching how non-numeric per-tool cost entries are already omitted.

* fix(proxy): count embedding and text completion tokens toward TPM limits (#30105)

* fix(proxy): count embedding and text completion tokens toward TPM limits

The parallel request limiters only read token usage off ModelResponse,
so EmbeddingResponse and TextCompletionResponse objects left
total_tokens at 0 and the per key, user, team, and end user TPM
counters never incremented. Requests to /v1/embeddings and
/v1/completions were effectively free against any tpm_limit. In the v3
limiter this was worse: the post-call reconciliation computed actual
usage as 0 and refunded the pre-call reservation made at request time.

Broaden the isinstance checks to accept EmbeddingResponse and
TextCompletionResponse, which both expose a Usage object, at the four
per-scope sites in parallel_request_limiter.py and at the usage
extraction in parallel_request_limiter_v3.py. ResponsesAPIResponse was
already covered in v3 via BaseLiteLLMOpenAIResponseObject.

Fixes #27738.

* test(proxy): cover v1 limiter TPM counting for embedding and text completion responses

Exercise the broadened isinstance sites in parallel_request_limiter.py
by asserting that async_log_success_event adds total_tokens to the per
key, user, team, and end user TPM counters for EmbeddingResponse and
TextCompletionResponse objects. The counters are pre-seeded at zero so
the assertion is exactly the increment; on the pre-fix code these
responses left total_tokens at 0 and the test fails.

litellm.completion() merges caller headers with extra_headers, but the
text-completion-openai branch never passed the merged dict to
openai_text_completions.completion(), and the handler only used its
headers argument for logging. Pass the merged headers through the call
site and set them as extra_headers on the outgoing request, mirroring
the chat completion handler, so x-* client headers forwarded by the
proxy reach the provider on /v1/completions.

Fixes #27410.

* Drop redundant extra_headers assignment and fix test module collision

completion() merges extra_headers into headers before the
text-completion-openai branch, and the handler now sets the merged
headers as extra_headers on the request, so the branch-local
optional_params["extra_headers"] assignment was a dead duplicate.
Removing it keeps the assignment in one place while both entry paths
(litellm.text_completion and direct handler callers) still forward
headers; a new regression test pins the extra_headers kwarg path.

Also rename the test module to test_completion_handler.py since its
basename collided with tests/test_litellm/llms/bedrock/batches/
test_handler.py and broke pytest collection.

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel and base64-encode the body (#30102)

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel

POST /v1/messages/count_tokens with Anthropic content blocks
({"type": "text"|"tool_use"|...}) was routed to the Converse input of
the Bedrock CountTokens API. The Converse transform copies list content
through verbatim, so Bedrock rejected the request with a 400 and the
caller silently fell back to the local tokenizer, returning counts that
can be off by ~50% on tool-heavy payloads.

_detect_input_type now routes messages whose content blocks carry a
"type" key (Anthropic shape) to the invokeModel input, which forwards
the body verbatim. The invokeModel body is now base64-encoded as the
CountTokens API requires (InvokeModelTokensRequest.body is a
base64-encoded blob), and Anthropic Messages bodies get the
anthropic_version and max_tokens fields Bedrock validates against.

Fixes #27632.

* fix(ui): show all session logs in the drawer, not just the first 50 (#29795)

* fix(ui): show newest session logs first

* test(ui): keep session log pagination coverage

* fix(ui): show all session logs in the drawer, not just the first page

The session detail drawer fetched session logs via sessionSpendLogsCall
without page/page_size, so it only ever received the backend default of one
page (50 rows). Sessions with more than 50 calls had the rest unreachable in
the UI (#29153).

sessionSpendLogsCall now takes page/page_size, and the drawer fetches the
first page, reads total_pages, then fetches the remaining pages and
accumulates them before the existing client-side sort. This keeps the single
continuous list (and the selected-log lookup and keyboard navigation, which
all assume the full session) correct. Fetching is bounded by a page cap, and
the sidebar shows a "showing most recent N" note if a session exceeds it.

The rows are lightweight metadata (the endpoint excludes messages/response),
so the full set is small; request/response bodies are still loaded per log on
demand.

* fix(ui): default session drawer to most recent log, newest first

Open a session with its most recent log selected, and order the sidebar
newest-first to match the all-sessions logs overview. MCP calls stay
grouped last. The latest log by time is computed explicitly, since the
MCP grouping means it is not always the first row.

* fix(vertex_ai): use REP host for context caching on eu/us multi-region endpoints (#29573)

Context caching built the cachedContents URL as
https://{location}-aiplatform.googleapis.com, which is an invalid host for the
eu/us multi-region endpoints and returns 404. The inference path already
resolves these to the REP host (https://aiplatform.{geo}.rep.googleapis.com)
via get_vertex_base_url(); reuse that helper in
_get_token_and_url_context_caching so caching uses the same host as inference.

Adds tests covering the eu/us multi-region cachedContents URLs (v1 and
v1beta1).

When Google GenAI / Vertex returns a 404 for deprecated or missing

* fix(proxy): allow clearing budget_duration and team_member fields by sending null on /key/update and /team/update

Fixes #27734

Sending null for budget_duration, team_member_budget,
team_member_budget_duration, team_member_rpm_limit, or
team_member_tpm_limit via /key/update or /team/update returned 200 OK
but silently ignored the null value. The fields remained unchanged in
the database.

Root causes:
- /key/update: prepare_key_update_data() popped budget_duration from the
  update dict but never re-added it (or budget_reset_at) when the value
  was None.
- /team/update: _set_budget_reset_at() only acted when budget_duration
  was non-None, leaving a stale budget_reset_at in the DB.
- /team/update: team_member_* null values bypassed the budget table
  update entirely because should_create_budget() requires at least one
  non-None field.

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes (#30028)

* fix(presidio): unmask PII tokens in Anthropic native SSE streaming bytes

When output_parse_pii=true on the Anthropic native path (anthropic/claude-*),
response chunks arrive as raw bytes in SSE format. _stream_pii_unmasking was
yielding those bytes unchanged, so <PERSON_1> tokens were never replaced with
the original values before reaching the caller.

Add _unmask_sse_bytes_chunk to parse each data: line, find content_block_delta
/ text_delta events, and apply _unmask_pii_text before re-encoding. Wire it
into _stream_pii_unmasking so bytes chunks are unmasked when pii_tokens exist.

* fix(presidio): handle CRLF line endings and non-ASCII PII in SSE unmask

Strip trailing \r before the [DONE] guard so CRLF-terminated SSE chunks
don't bypass it and silently swallow a JSONDecodeError. Add
ensure_ascii=False to json.dumps so non-ASCII replacement values like
accented names are preserved as UTF-8 on the wire rather than being
\uXXXX-escaped. Add regression tests for both cases.

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses) (#29925)

* feat(bedrock_mantle): path-aware Responses routing (/v1/responses vs /openai/v1/responses)

Bedrock Mantle serves the Responses API on two upstream paths:
  - gpt frontier models (gpt-5.5 / gpt-5.4) on /openai/v1/responses
  - every other Responses-capable model (e.g. gpt-oss) on the standard /v1/responses

BedrockMantleResponsesAPIConfig gains a `use_openai_path` flag; the provider gate in
utils.py picks the path per model: openai.gpt-* (non gpt-oss) -> /openai/v1/responses;
any model declared mode=responses (price-map entry or user model_info) -> /v1/responses;
everything else returns None and keeps the existing chat-completions emulation.

Adds gpt-5.5 / gpt-5.4 price-map entries, registry wiring, and the routing-matrix tests.

* feat(bedrock_mantle): data-driven frontier routing via use_openai_responses_path

Addresses the Greptile review point that frontier detection should be a
price-map field rather than a hardcoded name match. The gate now routes a
model to /openai/v1/responses when its price-map entry declares
use_openai_responses_path, so a frontier model whose name does not follow the
openai.gpt- convention can be onboarded by JSON alone. The name-convention
check is kept as a fallback that needs no price-map entry, which preserves
zero-change routing for a future gpt-6 before its entry loads. gpt-5.5 / gpt-5.4
get the flag in both price maps. Adds tests for the data-driven flag path and
for the flag presence on the gpt-5.x entries; both branches are mutation-tested.

* test(model_prices): allow use_openai_responses_path in price-map schema

The model_prices_and_context_window.json schema validator
(test_aaamodel_prices_and_context_window_json_is_valid) enforces
additionalProperties: false, so the new use_openai_responses_path flag on the
gpt-5.5 / gpt-5.4 entries failed validation. Add it to the schema as a boolean,
alongside the other supports_* / capability flags.

* fix(proxy): use Responses-API transformer in pass-through cost tracking (#29728)

The `elif is_responses:` branch of `openai_passthrough_handler` was
calling the chat-completions `transform_response` on a Responses API
payload. The chat-completions transformer expects `choices: [...]`
in the raw response; the Responses API uses `output: [...]` and
`usage.input_tokens` / `usage.output_tokens` (not
`prompt_tokens` / `completion_tokens`). The result was a
KeyError 'choices' deep inside `convert_to_model_response_object`,
swallowed by the surrounding `except Exception` in the handler, and
the SpendLogs row was written by the fallback path with zeroed-out
tokens, spend, and model.

This bug silently undercounts cost for every successful pass-through
call to either OpenAI's `/v1/responses` or Azure's
`/openai/v1/responses` (deployments configured for the Responses
API). Reproduced 2026-06-04 against a real Azure OpenAI Responses
API deployment proxied through LiteLLM v1.88.0.

Fix: use the dedicated
`OpenAIResponsesAPIConfig.transform_response_api_response` for the
Responses branch. This transformer already exists in LiteLLM
(`litellm/llms/openai/responses/transformation.py`) and knows the
Responses-API on-the-wire shape. `litellm.completion_cost` already
handles `ResponsesAPIResponse` natively with `call_type="responses"`,
so no downstream changes are needed.

Tests:

  test_responses_api_uses_responses_transformer_not_chat_completions
    NEW. Real regression test — exercises the openai_passthrough_handler
    with a real-shaped Responses payload (no `choices`, has `output`
    and Responses-API `usage` keys) and NO mocked `get_provider_config`.
    Pre-fix: raises KeyError 'choices' inside the chat-completions
    transformer (the bug). Post-fix: returns a ResponsesAPIResponse,
    completion_cost is called with call_type="responses" and a
    ResponsesAPIResponse instance (asserted).
    Verified to fail on un-fixed handler + pass on fixed handler
    before commit.

  test_responses_api_cost_tracking
    UPDATED. Old test mocked `get_provider_config` (no longer called
    in the responses branch post-fix). Now mocks the Responses
    transformer directly (`OpenAIResponsesAPIConfig.transform_response_api_response`)
    to test the downstream cost-calc contract.

* fix(anthropic): synthesize content_block_start when Responses stream omits output_item.added (#30115)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

a no-op setModelData, hardcoded empty organizations, no-op
setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

these wrappers rendered (ModelsAndEndpointsView, OrganizationFilters) stay,

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(anthropic): avoid index -1 content_block_delta in messages stream

When a /v1/messages request is routed through the Responses API
adapter, AnthropicResponsesStreamWrapper only emits content_block_start
on response.output_item.added. Some upstreams (LMStudio for example)
never send that event, so the text delta handler fell back to
_current_block_index, which starts at -1, and clients received
content_block_delta events with index -1 and no preceding
content_block_start. Anthropic SDKs then fail with "text part -1 not
found"

The text delta handler now synthesizes a content_block_start with a
fresh block index whenever the delta references an unregistered item_id
or no block is open yet, and registers the item_id so follow-up deltas
reuse the same index

Addresses the /v1/messages defect in #27442

* Make test sys.path shim resolve relative to the file, not the CWD

os.path.abspath("../../../../../../..") depends on where pytest is
invoked from; anchoring on os.path.dirname(__file__) makes the import
work from any working directory. Also corrects the depth: the repo root
is six levels above this file, not seven.

* fix: enable compact-2026-01-12 beta header for vertex_ai provider (#30114)

* fix(team): reserve team budget raises for proxy admins on /team/update (#30030)

The caller's PERSONAL max_budget was the wrong yardstick for /team/update: a
team's spend ceiling has nothing to do with the admin's own key budget. That
comparison was an unintended side effect of reusing _check_user_team_limits()
(which exists for the /team/new path) and broke the UI, which re-sends the
unchanged budget on every save.

New behavior on /team/update for standalone teams:
- A team admin (already authorized via _verify_team_access) may freely KEEP or
  LOWER the team budget, and change models/tpm/rpm, without being gated by their
  personal limits.
- GROWING a team's spend ceiling is a budget-authority action reserved for proxy
  admins -> 403 for team admins. "Growing" covers both raising max_budget above
  the team's current finite value and removing the cap entirely (max_budget=null,
  detected via model_fields_set so an explicit null is distinguished from an
  omitted field). For a team that currently has no cap, setting a finite value is
  a restriction and is allowed.
- Org-scoped teams remain governed by _check_org_team_limits() (capped by the
  org budget).

Also reverts the #29525 existing_team_max_budget workaround in
_check_user_team_limits() back to the create-only form; /team/new still enforces
the creator's personal caps.

docs(access_control): resolve the contradiction in the team-admin section —
team admins can keep/lower the budget and manage rate limits/models, but cannot
raise the team budget (proxy-admin only).

tests: unit + behavior coverage for raise-blocked, cap-removal-blocked (team
admin), raise/removal allowed (proxy admin), uncapped-team restriction allowed,
keep/lower/resend allowed, and unchanged create-path guards.

* test(ui): data-driven App Router migration E2E smoke (default + server-root-path) (#29974)

* test(ui): add a data-driven App Router migration E2E smoke

Add a growing Playwright smoke for migrated pages: for each segment it deep-links
to the path route, asserts the URL and that the dashboard shell rendered, then
clicks off to a legacy page and asserts navigation still works. Driven by
e2e_tests/fixtures/migratedPages.ts, so adding a page is one line.

Runs in two situations against the same proxy: the default mount (npm run
e2e:migration) and a non-root SERVER_ROOT_PATH mount (npm run e2e:migration:root).
globalSetup now logs in at `${SERVER_ROOT_PATH}/ui/login` so the admin storage
state is valid under a prefix. Seeded with api-reference; append the rest as their
migrations merge.

* test(ui): support headed slow-motion + watch pauses in the migration smoke

Honor SLOWMO in the server-root-path config (the default config already did),
and add an env-gated E2E_WATCH_MS pause so a headed run lingers on each state.
Both are no-ops by default, so CI behavior is unchanged.

* test(ui): make the migration smoke a sidebar-click user journey

Rework the smoke from deep-linking to a real navigation journey: start at the
landing page, click the migrated page in the sidebar (expanding submenus for
nested items), assert the path route rendered, reload it (the check a wrong
server_root_path breaks), bounce to a legacy page and back, and — once two pages
are migrated — navigate directly between two migrated pages. Verifies via URL +
shell render, driven by the same fixture list.

* test(ui): address review on the migration smoke

Escape ROOT and segment before interpolating them into RegExp URL matchers so a
future segment containing regex metacharacters can't silently widen the match.
Make the server-root-path config fail fast when SERVER_ROOT_PATH is unset instead
of silently re-running the default mount and passing without exercising the prefix.

* test(ui): drop unused watch helper and fix stale smoke README

* test(ui): run the migration smoke under a server root path in CI

* test(ui): harden + instrument the server-root-path proxy reboot in CI

* test(ui): run the server-root-path migration smoke as its own CI job

Replace the in-place proxy reboot in e2e_ui_testing with a dedicated
e2e_ui_testing_server_root_path job that boots the proxy once with
SERVER_ROOT_PATH=/litellm, matching how every other proxy variant in the
config gets its own job rather than killing and relaunching the live proxy.

The reboot was failing deterministically: after pkill -9 and relaunch the
prefixed proxy never came back up on :4000 (connection refused), so the smoke
never ran. The readiness step that was supposed to surface the cause could
never reach its boot-log tail because CircleCI runs steps under bash -eo
pipefail and the preceding `curl -sv ... | tail` aborted the step with curl's
exit 7. Booting the proxy as the job's own background step lets any boot crash
land in that step's log instead of being swallowed.

The default e2e_ui_testing job is unchanged aside from dropping the reboot,
prefixed-readiness, and prefixed-smoke steps; the migration smoke still runs at
the root mount there via the default Playwright config.

setUserRole/setUserEmail), so reaching one would render a degraded page in any
case. The real wrapper belongs in the PR that flips each page into
MIGRATED_PAGES, written with eyes on it and a test

Gate nudgesDisabled on the ui-settings loading state so an admin with

the flag resolves. Falls back to showing nudges if the fetch errors.

* test(ui): wrap CreateKeyPage test in QueryClientProvider

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI (#30064)

* Add Claude Fable 5 across Anthropic, Bedrock, Vertex AI, and Azure AI

Adds cost map entries for claude-fable-5 ($10/$50 per MTok, 1M context,
128K output, adaptive thinking only) on the Anthropic API, Bedrock
converse (base, global, and us/eu geo inference profiles at the 10%
regional premium), Vertex AI, and Azure AI (Microsoft Foundry, which
serves Fable 5 with the full 1M context window unlike Opus 4.8).

Registers anthropic.claude-fable-5 in BEDROCK_CONVERSE_MODELS, lists the
model in the setup wizard, and extends the reasoning effort e2e grid.
The Bedrock, Vertex, and Azure grid cells carry fail_reason markers
until the CI accounts are provisioned: Bedrock needs the provider data
sharing opt-in Fable 5 requires, and the Foundry resource needs a
claude-fable-5 deployment.

The first-party entry carries provider_specific_entry {us: 1.1} for the
inference_geo premium and deliberately no fast multiplier since Fable 5
has no fast mode.

* Drop removed sampling params for Claude 4.7+ when drop_params is set

Fable 5, Opus 4.7, and Opus 4.8 removed sampling params: the API rejects
top_p, top_k, and any temperature other than 1 with a 400. LiteLLM was
forwarding them even with drop_params enabled because the Anthropic and
Bedrock converse transformations passed temperature/top_p through
unconditionally.

Mirror the GPT-5/o-series handling: temperature=1 still passes through,
other values and any top_p are dropped when drop_params is set, and
without drop_params a clean client-side UnsupportedParamsError tells the
caller how to opt in, instead of surfacing the raw provider error.

* Drive sampling param gating from the cost map and cover top_k

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the

* fix: enable compact-2026-01-12 beta header for vertex_ai provider

The vertex_ai block in anthropic_beta_headers_config.json mapped
compact-2026-01-12 to null, so update_headers_with_filtered_beta
stripped the header before the request reached Vertex while the
compact_20260112 context edit stayed in the body, and Vertex rejected
the request with HTTP 400. Vertex rawPredict accepts the header, and
the bedrock and databricks blocks already forward it. Mirrors #21867,
which enabled context-1m-2025-08-07 for vertex_ai the same way.

Fixes #27290.

Greptile review follow-ups on the sampling param fix: the restriction for
Fable 5 / Opus 4.7 / 4.8 is now declared as supports_sampling_params: false
on every affected cost map entry (perplexity excluded; that route is
OpenAI-compatible and maps sampling params upstream) and read back through
a tri-state map lookup, keeping the name check only as a fallback for
provider-routed ids whose hosted map entries predate the flag, the same
layering supports_adaptive_thinking uses. top_k bypasses map_openai_params
as a provider-specific kwarg, so it is gated at the shared
AnthropicConfig.transform_request boundary (direct, Bedrock invoke, Vertex,
Azure) and in the Bedrock converse _handle_top_k_value path, with
drop_params threaded through the converse transform helpers.

Also updates the reasoning effort grid cell count assertion for the four
Fable 5 rows added on this branch (29 x 11 cells).

* Declare supports_sampling_params in the cost map schema

The model map validation schema uses additionalProperties: false, so the
new flag must be declared for the 28 entries that carry it; this was the
one failing job (misc / Run tests) on the previous commit.

https://claude.ai/code/session_01MZarYYT3aS7DxaNjoax6Gm

* fix(bedrock): gate top_k=0 on converse to match Anthropic boundary

Truthiness check let top_k=0 silently disappear on models that removed
sampling params, while AnthropicConfig.transform_request treats 0 as
present and raises UnsupportedParamsError (or drops when drop_params is
set). Switch to 'is not None' so converse, direct Anthropic, invoke,
Vertex, and Azure all behave the same for top_k=0.

* fix(proxy): coerce litellm_settings.max_budget env var to float

When max_budget is set in litellm_settings via os.environ/MAX_BUDGET,
the env var resolves to a string and the generic setattr branch in
ProxyConfig.load_config stored it as-is, so the startup check
litellm.max_budget > 0 raised TypeError. The earlier fix (#23855) only
covered the CLI initialize() path. Coerce the value to float in the
settings loop, matching the existing max_internal_user_budget handling.

Fixes #26696.

* fix(router): don't drop bedrock pass-through deployments using IAM credentials (#30111)

* Fix Bedrock passthrough deployment dropped when using IAM credentials

Bedrock deployments with use_in_pass_through enabled and IAM/OIDC auth
(aws_role_name, no api_key) hit the generic pass-through branch in
Router._initialize_deployment_for_pass_through, which calls
set_pass_through_credentials and raises "api_key is required". The
exception drops the deployment from the router entirely, breaking both
passthrough and normal routing for that model.

Skip the credential store write when no api_key is set; the bedrock
passthrough route resolves AWS credentials at request time via
BedrockConverseLLM.get_credentials(), not the passthrough credential
store, so there is nothing to register here.

Fixes #27728.

* Reset passthrough credentials singleton before api_key credential test

The test reads the module-level passthrough_endpoint_router singleton,
so a stale "openai" entry written by an earlier test in the same
process could make the assertion pass without exercising the code path.
Clearing the credentials dict up front makes the test order-independent.

* fix(sdk): stop mirroring reasoning_content in provider_specific_fields (#30110)

The dict-to-response conversion path mirrored reasoning_content into
provider_specific_fields, while live provider transforms (Anthropic's
_build_provider_specific_fields) only set it top-level on the Message.
Cache-replayed messages therefore serialized differently from live
ones, breaking disk cache key stability for multi-turn conversations
with extended thinking.

The mirror was added for DeepSeek before Message.reasoning_content
existed as a top-level attribute. The top-level field is still set by
the converter, so DeepSeek's request-side promotion is unaffected.

Fixes #27337.

* fix(mcp): coerce mcp_server_cost_info values to float at ingest (#30109)

* fix(mcp): coerce mcp_server_cost_info values to float at ingest

YAML 1.1 parses scientific notation without a decimal point
(e.g. 7e-05) as a string, and MCPServerCostInfo is a TypedDict with no
runtime validation, so a string-typed default_cost_per_query from
config.yaml flowed through the proxy untouched and crashed the MCP
server settings page with '.toFixed is not a function'. Normalize
mcp_server_cost_info on both the config and DB load paths, dropping
non-numeric values with a warning instead of failing the server load.

Fixes #27097.

* fix(mcp): drop non-numeric default_cost_per_query instead of nulling it

Keeping the key with a None value still exposes a null to the UI,
which can crash .toFixed formatting when the consumer checks key
existence rather than truthiness. Delete the key on coercion failure,
matching how non-numeric per-tool cost entries are already omitted.

* fix(proxy): count embedding and text completion tokens toward TPM limits (#30105)

* fix(proxy): count embedding and text completion tokens toward TPM limits

The parallel request limiters only read token usage off ModelResponse,
so EmbeddingResponse and TextCompletionResponse objects left
total_tokens at 0 and the per key, user, team, and end user TPM
counters never incremented. Requests to /v1/embeddings and
/v1/completions were effectively free against any tpm_limit. In the v3
limiter this was worse: the post-call reconciliation computed actual
usage as 0 and refunded the pre-call reservation made at request time.

Broaden the isinstance checks to accept EmbeddingResponse and
TextCompletionResponse, which both expose a Usage object, at the four
per-scope sites in parallel_request_limiter.py and at the usage
extraction in parallel_request_limiter_v3.py. ResponsesAPIResponse was
already covered in v3 via BaseLiteLLMOpenAIResponseObject.

Fixes #27738.

* test(proxy): cover v1 limiter TPM counting for embedding and text completion responses

Exercise the broadened isinstance sites in parallel_request_limiter.py
by asserting that async_log_success_event adds total_tokens to the per
key, user, team, and end user TPM counters for EmbeddingResponse and
TextCompletionResponse objects. The counters are pre-seeded at zero so
the assertion is exactly the increment; on the pre-fix code these
responses left total_tokens at 0 and the test fails.

* fix(openai): forward client headers on the text completion path (#30103)

* fix(openai): forward client headers on the text completion path

litellm.completion() merges caller headers with extra_headers, but the
text-completion-openai branch never passed the merged dict to
openai_text_completions.completion(), and the handler only used its
headers argument for logging. Pass the merged headers through the call
site and set them as extra_headers on the outgoing request, mirroring
the chat completion handler, so x-* client headers forwarded by the
proxy reach the provider on /v1/completions.

Fixes #27410.

* Drop redundant extra_headers assignment and fix test module collision

completion() merges extra_headers into headers before the
text-completion-openai branch, and the handler now sets the merged
headers as extra_headers on the request, so the branch-local
optional_params["extra_headers"] assignment was a dead duplicate.
Removing it keeps the assignment in one place while both entry paths
(litellm.text_completion and direct handler callers) still forward
headers; a new regression test pins the extra_headers kwarg path.

Also rename the test module to test_completion_handler.py since its
basename collided with tests/test_litellm/llms/bedrock/batches/
test_handler.py and broke pytest collection.

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel and base64-encode the body (#30102)

* fix(bedrock): route Anthropic-shape count_tokens to InvokeModel

POST /v1/messages/count_tokens with Anthropic content blocks
({"type": "text"|"tool_use"|...}) was routed to the Converse input of
the Bedrock CountTokens API. The Converse transform copies list content
through verbatim, so Bedrock rejected the request with a 400 and the
caller silently fell back to the local tokenizer, returning counts that
can be off by ~50% on tool-heavy payloads.

_detect_input_type now routes messages whose content blocks carry a
"type" key (Anthropic shape) to the invokeModel input, which forwards
the body verbatim. The invokeModel body is now base64-encoded as the
CountTokens API requires (InvokeModelTokensRequest.body is a
base64-encoded blob), and Anthropic Messages bodies get the
anthropic_version and max_tokens fields Bedrock validates against.

Fixes #27632.

* refactor(bedrock): name the CountTokens max_tokens placeholder

Replace the magic 1024 with a module-level
DEFAULT_ANTHROPIC_INVOKE_MODEL_MAX_TOKENS constant so the intent is
explicit and there is a single place to update if Bedrock's InvokeModel
schema ever changes. Module-local rather than litellm/constants.py
because the value is only a schema-validation placeholder for token
counting, not a user-tunable generation default.

* Add above-512k pricing tier for MiniMax-M3 and correct its base rates (#30095)

* Add above-512k pricing tier support for MiniMax-M3

MiniMax-M3 doubles its per-token rates once a prompt exceeds 512k
input tokens. The tiered cost parser already handles arbitrary
thresholds, but get_model_info only copies whitelisted keys from
ModelIn…

#### Verify Docker Image Signature

All LiteLLM Docker images are signed with [cosign](https://docs.sigstore.dev/cosign/overview/). Every release is signed with the same key introduced in [commit `0112e53`](BerriAI/litellm@0112e53).

**Verify using the pinned commit hash (recommended):**

A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

**Verify using the release tag (convenience):**

Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/v1.90.0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

Expected output:

```
The following checks were performed on each of these signatures:
  - The cosign claims were validated
  - The signatures were verified against the specified public key
```

##### Verify Docker Image Signature

All LiteLLM Docker images are signed with [cosign](https://docs.sigstore.dev/cosign/overview/). Every release is signed with the same key introduced in [commit `0112e53`](https://github.com/BerriAI/litellm/commit/0112e53046018d726492c814b3644b7d376029d0).

**Verify using the pinned commit hash (recommended):**

A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

**Verify using the release tag (convenience):**

Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/v1.90.0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

Expected output:

```

[Compare Source](https://github.com/BerriAI/litellm/compare/v1.89.4...v1.90.0)

##### Verify Docker Image Signature

All LiteLLM Docker images are signed with [cosign](https://docs.sigstore.dev/cosign/overview/). Every release is signed with the same key introduced in [commit `0112e53`](https://github.com/BerriAI/litellm/commit/0112e53046018d726492c814b3644b7d376029d0).

**Verify using the pinned commit hash (recommended):**

A commit hash is cryptographically immutable, so this is the strongest way to ensure you are using the original signing key:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/0112e53046018d726492c814b3644b7d376029d0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

**Verify using the release tag (convenience):**

Tags are protected in this repository and resolve to the same key. This option is easier to read but relies on tag protection rules:

```bash
cosign verify \
  --key https://raw.githubusercontent.com/BerriAI/litellm/v1.90.0/cosign.pub \
  ghcr.io/berriai/litellm:v1.90.0
```

Expected output:

```
The following checks were performed on each of these signatures:
  - The cosign claims were validated
  - The signatures were verified against the specified public key
```
