feat: Add Amazon Nova 2 Lite model to Bedrock provider #9830

roomote · 2025-12-04T16:40:23Z

This PR attempts to address Issue #9802. Feedback and guidance are welcome!

Summary

Added support for Amazon Nova 2 Lite model in the Bedrock provider, as requested in issue #9802.

Changes

Added amazon.nova-lite-v2:0 model definition to packages/types/src/providers/bedrock.ts
Configured with 300k context window and image support (matching Nova Lite v1 capabilities)
Set pricing slightly higher than Nova Lite v1 but still competitive with Claude Haiku 4.5
Enabled prompt caching and native tools support

Testing

✅ Type checking passes
✅ All existing tests pass
✅ Linting passes

Notes

The model configuration is based on the issue description mentioning that Nova 2 Lite is comparable to Claude Haiku 4.5. The exact pricing and capabilities may need adjustment once official AWS documentation is available.

Fixes #9802

All issues resolved. The model has been correctly configured with the right model ID, pricing, context window, and maxTokens.

Move nova-lite-v2 definition to be placed immediately after nova-lite-v1 for better code organization
Update maxTokens to 65_535 (per reviewer suggestion)

+	"amazon.nova-lite-v2:0": {
+		maxTokens: 5000,
+		contextWindow: 300_000,
+		supportsImages: true,
+		supportsPromptCache: true,

+	},


The nova-lite-v2 model should be placed immediately after nova-lite-v1 (line 70) rather than after nova-micro-v1 (line 84). This maintains the logical grouping of model versions together (Pro v1, Pro latency-optimized, Lite v1, Lite v2, Micro v1) which improves code readability and makes it easier to compare related models.

_{Fix it with Roo Code or mention @roomote and request a fix.}

@roomote
Input Price = $0.33
OutputPrice = $2.75
Cache read input tokens will be 75% less than on-demand input token price
Context Window = 1M

This seems to work. However, according to the official documentation, the model ID is us.amazon.nova-2-lite-v1:0

When new_task triggers delegation, the parent is disposed before these pending results are saved, causing 400 errors when the parent resumes (missing tool_result for tool_use). This fix: - Adds flushPendingToolResultsToHistory() method in Task.ts that saves pending userMessageContent to API history - Calls this method in delegateParentAndOpenChild() before disposing the parent task - Safe for both native/XML protocols and sequential/parallel execution (returns early if there's nothing to flush) * Better IPC error logging (RooCodeInc#9727) * chore: add changeset for v3.35.1 (RooCodeInc#9728) * Changeset version bump (RooCodeInc#9729) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Matt Rubens <[email protected]> * Pass app version to provider (RooCodeInc#9730) * Allow models to contain default temperature (RooCodeInc#9734) * Look for a tag in the Roo provider to default the model to native tool calling (RooCodeInc#9735) * Assume all LiteLLM models support native tools (RooCodeInc#9736) * chore: add changeset for v3.35.2 (RooCodeInc#9737) * Changeset version bump (RooCodeInc#9738) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Matt Rubens <[email protected]> * Merge remote-tracking branch 'upstream/main' into roo-to-main * Switch to new welcome view (RooCodeInc#9741) * web: Homepage changes (RooCodeInc#9675) Co-authored-by: roomote[bot] <219738659+roomote[bot]@users.noreply.github.com> Co-authored-by: ellipsis-dev[bot] <65095814+ellipsis-dev[bot]@users.noreply.github.com> * Add vendor confidentiality section to the system prompt for stealth models (RooCodeInc#9742) Co-authored-by: roomote[bot] <219738659+roomote[bot]@users.noreply.github.com> * chore: add changeset for v3.35.3 (RooCodeInc#9743) * Changeset version bump (RooCodeInc#9745) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Matt Rubens <[email protected]> * Refactor: Remove line_count parameter from write_to_file tool (RooCodeInc#9667) * fix: remove reasoning toggles for GLM-4.5 and GLM-4.6 on z.ai provider (RooCodeInc#9752) Co-authored-by: Roo Code <[email protected]> * fix: handle malformed native tool calls to prevent hanging (RooCodeInc#9758) Co-authored-by: Matt Rubens <[email protected]> * chore: add changeset for v3.35.4 (RooCodeInc#9763) * Changeset version bump (RooCodeInc#9764) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Matt Rubens <[email protected]> * Convert the Roo provider tools for OpenAI (RooCodeInc#9769) * Update the evals keygen command (RooCodeInc#9754) * feat: Add provider routing selection for OpenRouter embeddings (
