Fixes #2557

Summary

A roster pass that stops on finish_reason: length reached the model and was billed. It is neither "model unreachable" nor "answers too thin", but #2556 reported it as not_designable and left the wording vague. This adds FallbackReason::OutputBudgetExhausted (wire value output_budget_exhausted) and uses it for that stop. Both setup screens (the setup dialog and the wizard review step) now say the model ran out of output room, with a "Try again" button and a pointer to pick a model with a larger output limit in Settings.

API Or Behavior Changes

  • New fallback reason on the setup roster response: reason: "output_budget_exhausted". A length stop used to come back as not_designable.
  • Frontend RosterFallback and SetupRoster.reason types accept the new value.
  • No other behavior change. The fallback team and the 4,000 token cap stay as they are.

Tests

I did not run any of these locally. The patch was prepared without a local build, so CI is its first run.

  • cargo fmt --all -- --check
  • cargo clippy --all-targets -- -D warnings
  • cargo build --all-targets
  • cargo test

Tests updated or added: the existing roster build and setup route tests now expect OutputBudgetExhausted / output_budget_exhausted (including the wire spelling), and a new frontend unit test checks that the dialog offers a retry and not the add-a-model button for this reason.

Documentation

No docs needed. The user-facing copy lives in the setup screens.

Summary by CodeRabbit

  • New Features
    • Setup now identifies when a model reaches the 4,000-token output cap before producing a usable roster, distinguishing this from other fallback cases.
    • The setup screen explains the output-limit issue and offers a retry. The review step also suggests retrying or editing the roster; choosing a model with a larger output limit alone will not resolve the issue.

A roster pass that stops on finish_reason=length reached the model and was
billed; it is neither unreachable nor too-thin answers. Add
FallbackReason::OutputBudgetExhausted (wire: output_budget_exhausted) and
say so on both setup screens, with a retry.

description

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The change introduces a new `FallbackReason::OutputBudgetExhausted` variant with a corresponding wire value `output_budget_exhausted`, updates the backend code that maps a length stop to this new reason, and adds frontend handling with a dedicated user-facing message and a 'Try again' button. All code appears correctly implemented and consistent across the stack. No problems are introduced. _Code retrieval was unavailable (model: ladder embeddings returned 402 Payment Required: {"error":"Insufficient USD or Diem balance to complete request. Visit https://venice\.ai/settings/api to add credits."}), so this review saw the diff alone._ _2 memory call(s) failed (model: cortex: v1/answer: timed out after 20s), so this review saw part of what the engine holds._

e2e

  • Conclusion: Neutral
  • Scope reviewed: all assigned evidence
  • Lane summary: This change adds a new `OutputBudgetExhausted` variant to `FallbackReason`, wired through the core, server, API types, and frontend. The new reason surfaces with its own UI copy and a retry button. The existing end-to-end test in `setup_test_group_8.rs` was updated to assert the new wire value, and a new frontend unit test covers the dialog behaviour. The change is well-structured and all modified paths (core enum, server serialization, API union, frontend render) are covered by the updated or new unit tests. No external surface remains untested by any end-to-end harness. Waiting on end-to-end jobs: `Console E2E`, `Console E2E (live brain)`, `Console E2E (first run)`.

📝 Walkthrough

Walkthrough

Roster setup now reports output-token exhaustion as a distinct fallback reason. Backend and frontend types include the new reason. Both setup screens explain the exhausted output limit, and the completion screen offers a retry.

Explanation

[#2557] The PR adds OutputBudgetExhausted, returns it for the length-stop case, updates the wire and frontend types, and gives both setup screens copy that states the 4,000-token cap. The copy does not say where to change that cap, as the issue requires. The new frontend regression test covers the dialog; the available evidence does not establish matching coverage for the wizard review copy.

“The output budget stopped the quote.”
It taps “Try again” with its paw,
Then checks the limit, clear and raw.

And carrots make the retry sweet.

Comment thread frontend/src/setup/SetupDialog.tsx Resolved
The roster request asks for at most 4,000 output tokens, so picking a model with a larger limit does not raise it. Drop that advice from the output-budget messages and state the cap.

Thanks. On the file-size item: company/setup.rs (1,669 lines) and server/setup.rs (2,248) are already over 750 on main, and CI currently runs the layout script in tests mode only, so this PR does not change that. Splitting them is a separate refactor. On the budget wording: agreed, the messages now state the 4,000 output-token cap directly so a larger model limit alone is not suggested as a fix (018312f).
