[BUG] Bedrock models "minimax.minimax-m2.5" and "moonshotai.kimi-k2.5" unavailable and fallback to Claude Sonnet

[gianlucacandiotti]

Problem (one or two sentences)

When using RooCode with Amazon Bedrock, I am unable to select or use the Bedrock models minimax.minimax-m2.5 and moonshotai.kimi-k2.5. These models are available in my Bedrock model catalog and work with other tools (such as Open Code), but do not show up for selection in RooCode. Attempting to add them as a custom model fails, and when enabling "Global inference" as suggested by the fallback message, RooCode silently switches to an Anthropic Claude Sonnet 4.5 model instead. This resulted in much higher AWS billing, as the fallback model is significantly more expensive.

Context (who is affected and when)

I would assume everyone trying to use these models through Amazon Bedrock.

Reproduction steps

Environment

• Platform: Cursor Version: 3.3.27 (Universal) / VSCode Version: 1.105.1
• Operating system: macOS Tahoe 26.4
• Region configured in Bedrock: I've tried eu-north-1 and us-east-1
• Models attempted: minimax.minimax-m2.5, moonshotai.kimi-k2.5

Steps to Reproduce

1. Configure RooCode to use Amazon Bedrock as the provider, with a supported region.
2. Attempt to select either minimax.minimax-m2.5 or moonshotai.kimi-k2.5 as the agent/model.
3. Observe that these models do not appear in the model selection dropdown, despite being available in AWS Bedrock.
4. Attempt to add the model as a custom model.
5. Receive an error, possibly suggesting "enable Global inference."
6. When "Global inference" is enabled, RooCode selects/antrhopic.claude-sonnet-4.5 instead.
7. Usage of this fallback results in unexpected, high AWS Bedrock billing.

Expected result

The models minimax.minimax-m2.5 and moonshotai.kimi-k2.5 should appear as selectable agents when they are visible and available via AWS Bedrock.

Actual result

These Bedrock models are missing from the agent selection and attempting to add them as custom models does not work.

I've analyzed this issue and here's my proposed implementation plan:

The Bedrock model definitions in packages/types/src/providers/bedrock.ts currently include moonshot.kimi-k2-thinking and minimax.minimax-m2, but are missing the two models you need: minimax.minimax-m2.5 and moonshotai.kimi-k2.5.

Proposed changes:

1. Add minimax.minimax-m2.5 to the bedrockModels object in packages/types/src/providers/bedrock.ts with appropriate specs (context window, max tokens, pricing based on AWS Bedrock pricing docs)
2. Add moonshotai.kimi-k2.5 to the same bedrockModels object (note: the existing Kimi model uses the moonshot. prefix -- I'll verify the correct Bedrock model ID, which may be moonshot.kimi-k2.5 rather than moonshotai.kimi-k2.5)
3. Update related tests to cover the new model entries

A quick question: Could you confirm the exact model IDs as they appear in your AWS Bedrock console? The existing Kimi model in the codebase uses the moonshot. prefix (e.g. moonshot.kimi-k2-thinking), but you mentioned moonshotai.kimi-k2.5. If you can share the exact IDs from your Bedrock model catalog, that would help ensure we add the right entries.

Please mention @roomote in a comment saying that you approve this plan, and I'll proceed with the implementation.

[gianlucacandiotti]

• MiniMax M2.5 model ID is "minimax.minimax-m2.5".
• Kimi K2.5 model ID is "moonshotai.kimi-k2.5".

[gianlucacandiotti]

@roomote your plan sounds good, please proceed.

[roomote-v0]

I've seen your approval and will proceed with the implementation. I'll add both minimax.minimax-m2.5 and moonshotai.kimi-k2.5 to the Bedrock model definitions and open a PR to share progress.

[roomote-v0]

Opened PR #12299 with my attempt at addressing this. It adds both minimax.minimax-m2.5 and moonshotai.kimi-k2.5 to the Bedrock model definitions. Feedback welcome!
