Administrator Guidance
Copilot Enterprise administrators may need to enable access to alternative models through their model policies in Copilot settings. As an administrator, you can verify availability by:
- Checking your individual Copilot settings.
- 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 are encouraged to reach out to their account manager for further assistance.
