Selected models in GitHub Copilot deprecated

GitHub deprecated four models across all GitHub Copilot experiences on October 2, 2026: Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7. GitHub recommends Gemini 3.8 Flash for both Gemini models, Kimi K3 for Kimi K2.7 Code, and Claude Opus 5.5 for Claude Opus 4.7, and advises users to update workflows and integrations to supported models. Copilot Enterprise administrators may need to enable access to the alternative models through model policies in Copilot settings, though no action is required to remove the deprecated models.
