Mistral Models for Copilot Chat

Mistral Models extension for seamless integration with Copilot Chat

Mistral AI • Mistral API Docs • Get Mistral API Key

Based on selfagency/mistral-models-vscode, which was based on OEvortex/vscode-mistral-copilot-chat (now discontinued). Substantially rewritten.

What is this?

Model Selection

Tooling Integration

Real-time Data Display

Why?

The idea is great. Implementation lacked elements I wanted, so I polished and reworked the codebase into modular, thoroughly tested, and maintainable architecture. Big thanks for the idea and inspiration to selfagency and OEvortex.

Need more?

Open an issue for any feature you want which i will evaluate on a case by case basis. I will try to keep the extension as simple as possible, and as feature-perfect to the Copilot Chat experience as possible, but i am open to suggestions.
