Kimi Copilot Provider

VS Code extension that registers Kimi K2/K2.7 Code models as a custom language model provider for GitHub Copilot Chat. Proxies chat requests to the Kimi API via SSE streaming.

Supported Models

How It Works

The extension implements the vscode.lm.LanguageModelChatProvider API (stabilized in VS Code 1.93+) and forwards chat requests to the Kimi API:

POST https://api.kimi.com/coding/v1/chat/completions

Kimi's API is OpenAI-compatible and supports SSE streaming.

Setup

1. Install dependencies and compile

npm install
npm run compile

2. Configure API Key

Run Kimi Copilot: Set API Key from the Command Palette (Ctrl+Shift+P) and paste your Kimi API key.

Or open VS Code Settings (Ctrl+,) and search for kimiCopilot:

3. Press F5 to Launch

Press F5 in VS Code to start the Extension Development Host. The Kimi provider will be available to Copilot Chat.

2. provideLanguageModelChatResponse — streams response via Progress<LanguageModelResponsePart>
3. provideTokenCount — estimates token count
