Please update your workflows and integrations to use the supported models before these dates. Copilot Enterprise administrators may need to enable access to the alternative models through their model policies in Copilot settings. As an administrator, you can verify availability by checking your individual Copilot settings and confirming that the policy is enabled for the specific model. Once enabled, you’ll see the model in the Copilot Chat model selector in VS Code and on github.com. No action is required to remove the older models once they have been deprecated.
