Key point

GitHub Copilot will end support for Grok Code Fast 1 on May 15.

Details

Support for Grok Code Fast 1 across GitHub Copilot will end on 2026-05-15.

The scope of this change covers Copilot Chat, inline edits, ask/agent mode, and code completions.

The replacement models are GPT-5 mini and Claude Haiku 4.5. This schedule was moved up due to deprecation on the model provider's side, and Copilot Enterprise admins may need to enable access to the replacement models in advance via model policies.

Once enabled, these models will appear in the Copilot Chat model picker in VS Code and on github.com. No separate removal action is needed after the retirement. If there are issues, users can contact their GitHub Enterprise account administrator.
