Please update your workflows and integrations to use the supported models before this date. Copilot Enterprise and Copilot Business administrators may need to enable access to the alternative models through their model policies in Copilot settings.

As an administrator, you can verify availability in your organization or enterprise Copilot model settings and confirm that the policy is enabled for the specific model. Once enabled, users will see the model in the Copilot Chat model selector in supported GitHub Copilot experiences.

No action is required to remove the models after they have been deprecated.

GitHub Enterprise customers with questions or concerns are encouraged to contact their account team for assistance.
