GitHub Copilot Retires GPT-5.2 and GPT-5.2-Codex Models Across Most Services
Key Takeaways
- ▸GPT-5.2 and GPT-5.2-Codex models are deprecated across most GitHub Copilot services as of June 5, 2026, though GPT-5.2 remains available for code review
- ▸Users and organizations must update their workflows and integrations to use supported alternative models
- ▸GitHub Enterprise administrators can enable alternative models through Copilot settings and model policies in the model selector
Summary
GitHub has deprecated GPT-5.2 and GPT-5.2-Codex models across most GitHub Copilot experiences effective June 5, 2026, including Copilot Chat, inline edits, ask mode, agent modes, and code completions. However, GPT-5.2 remains available for Copilot code review functionality, ensuring existing code review workflows continue to operate.
Developers and organizations using GitHub Copilot must update their workflows and integrations to use supported alternative models. GitHub Enterprise administrators can configure access to alternative models through their Copilot settings and model policies. The transition is seamless, with no manual action required to remove the deprecated models—they will simply no longer appear in the model selector once the change takes effect.
For customers with questions about the transition, GitHub Enterprise account managers are available to provide guidance. Developers are encouraged to consult GitHub's documentation on available models to understand their options and plan their migration strategy.
- No manual action is required to remove deprecated models; they will be automatically unavailable in Copilot experiences
