Deprecation Details
We will deprecate Grok Code Fast 1 across all GitHub Copilot experiences (including Copilot Chat, inline edits, ask and agent modes, and code completions) on May 15 2026:
| Model | Deprecation date | Suggested alternative |
|---|---|---|
| Grok Code Fast 1 | 2026-05-15 | GPT‑5 mini / Claude Haiku 4.5 |
The deprecation date is accelerated due to the model provider deprecation.
Required Actions
Please update your workflows and integrations to use supported models before this date. Copilot Enterprise administrators may need to enable access to alternative models through their model policies in Copilot settings.
- Verify availability by checking your individual Copilot settings and confirming that the policy is enabled for the specific model.
- Once enabled, the model will appear in the Copilot Chat model selector in VS Code and on github.com.
- No action is required to remove the models once they have been deprecated.
Support
GitHub Enterprise customers with questions or concerns should reach out to their account manager for assistance.
