[zortos293]

This pull request introduces improvements to Copilot model handling, including updating the list of available models, refining model ordering logic, and enhancing alias mapping and normalization. The changes ensure that model pickers display Copilot models in a preferred order, new models and aliases are supported, and tests are added to verify these behaviors.

Copilot Model Options and Aliases

• Added new Copilot models (gpt-5.4-mini, gemini-3.1-pro, raptor-mini) to MODEL_OPTIONS_BY_PROVIDER, and updated MODEL_SLUG_ALIASES_BY_PROVIDER to support aliases like "5.4-mini", "gemini-3.1", and "raptor" for these models. [1] [2] [3] [4] [5]

• Updated tests in model.test.ts to verify normalization and resolution of new Copilot model aliases and options. [1] [2]

Model Picker Ordering Logic

• Implemented orderCopilotBuiltInModelOptions in ChatView.logic.ts to reorder runtime Copilot models to match the preferred built-in picker order, and integrated it into the ChatView.tsx model picker logic. [1] [2] [3]

• Added unit tests for orderCopilotBuiltInModelOptions to ensure correct ordering and handling of unknown models. [1] [2]

Dependency Updates

📝 Walkthrough

Walkthrough

This pull request updates GitHub Copilot integration by bumping dependency versions, adding three new model options (gpt-5.4-mini, gemini-3.1-pro, raptor-mini) with corresponding slug aliases, and introducing an orderCopilotBuiltInModelOptions function to reorder model choices. The function sorts Copilot models by a preferred order before display in the UI. Test coverage is added for the new function and slug alias handling. Changes span dependency updates, model configuration, UI logic, and comprehensive test additions across multiple packages.
