support o3-mini

[shpigunov]

Description

This PR adds support for OpenAI’s new o3-mini model to Roo Code by updating its model configuration. The changes update the o3-mini entry to reflect the correct settings as per the latest OpenAI API documentation. Specifically, the configuration now sets:

• maxTokens to 100,000,
• contextWindow to 200,000,
• supportsImages to false (since o3-mini does not support vision),
• supportsPromptCache remains false,
• and pricing at $1.10 per 1M input tokens and $4.40 per 1M output tokens.

No modifications were needed in the handler’s logic because the existing routing and streaming code already correctly supports models outside of the o1 series.

Type of change

• New feature

How Has This Been Tested?

• Tests have been added to openai-native.test.ts
• Ensured that the tests pass by updating the expected response from o3-mini

Checklist:

• My code follows the patterns of this project
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation

Additional context

The primary change is within the shared model configuration file where the o3-mini entry is updated. The handler logic remains unchanged because o3-mini falls under the default branch (streaming with system prompt) and is correctly managed by the existing implementation. This update ensures consistency with the latest OpenAI pricing and feature specifications.

Important

Add support for OpenAI's o3-mini model with updated configuration and test case.

• Behavior:
  • Add support for o3-mini model in openAiNativeModels in api.ts with maxTokens 100,000, contextWindow 200,000, supportsImages false, supportsPromptCache false, inputPrice $1.10, outputPrice $4.40.
  • No changes to handler logic as existing code supports non-o1 models.
• Testing:
  • Add test case in openai-native.test.ts to verify completePrompt with o3-mini model.
