Summary
GitHub announced the deprecation of GPT-5.2 and GPT-5.2-Codex models across most GitHub Copilot experiences effective June 1st, 2026. The models will be retired from Copilot Chat, inline edits, ask and agent modes, and code completions, with GPT-5.2-Codex continuing to be available exclusively in Copilot Code Review.
Developers and organizations using these models must update their workflows and integrations to use alternative supported models before the deprecation deadline. GitHub Enterprise administrators are instructed to enable access to alternative models through their model policies in Copilot settings, ensuring all users have access to updated options through the Copilot Chat model selector in VS Code and on github.com.
The deprecation is part of GitHub's strategy to evolve its AI-powered development toolkit. Enterprise customers with concerns or questions are encouraged to reach out to their account managers for guidance on transitioning to supported models.
- No manual action is required to remove deprecated models once discontinued
