Summary
GitHub announced that it will deprecate the GPT-5.2 and GPT-5.2-Codex models across most GitHub Copilot experiences (including Copilot Chat, inline edits, ask and agent modes, and code completions) on June 1st, 2026. Notably, GPT-5.2-Codex will continue to be available in Copilot Code Review. This deprecation requires developers to migrate their workflows and integrations to supported alternative models before the deadline.
Copilot Enterprise administrators will need to enable access to alternative models through their model policies in Copilot settings. Administrators can verify model availability by checking individual Copilot settings and confirming that policies are enabled for specific models. Once enabled, users will see alternative models in the Copilot Chat model selector in VS Code and on github.com.
No action is required to remove the deprecated models after the deadline passes. GitHub Enterprise customers with questions about the transition are encouraged to contact their account managers for further assistance.
