GitHub began rolling out xAI’s reasoning model Grok 4.6 in GitHub Copilot on August 14, 2026 ¹. It covers the Copilot Pro, Pro+, Max, Business, and Enterprise SKUs, billed at provider list pricing under usage-based billing ¹. It can be selected from the model picker in Visual Studio Code, Visual Studio, Copilot CLI, GitHub Copilot cloud agent, the GitHub Copilot app, JetBrains, Xcode, and Eclipse ¹. Rollout is gradual ¹.

GitHub says that in its internal testing, Grok 4.6 showed strong results across terminal-based coding tasks in VS Code and Copilot CLI, performing especially well on longer-horizon tasks requiring sustained reasoning and tool use ¹. Copilot Enterprise and Business administrators must enable the Grok 4.6 policy in Copilot settings; it is off by default ¹. Gemini 3.7 Flash was added the same way a day earlier, on August 13.
