Grok for GitHub Copilot Chat

Use xAI Grok models directly from the GitHub Copilot Chat model picker in Visual Studio Code.

This extension is a native VS Code LanguageModelChatProvider. It authenticates with xAI, discovers available models, and streams responses from api.x.ai into Copilot Chat without a local proxy.

Highlights

• Browser/PKCE and device-code xAI sign-in with token refresh
• Live Grok model discovery
• Streaming text and reasoning
• Agent mode tool calls and image inputs
• Usage and cost metadata when returned by xAI
