Summary
Google has deprecated the Gemini 2.5 Pro and Gemini 3 Flash models across all GitHub Copilot experiences effective July 31, 2026. The deprecation affects Copilot Chat, inline edits, ask mode, agent mode, and code completions—requiring developers to migrate their workflows and integrations to supported models.
Copilot Enterprise administrators must proactively enable access to alternative models through model policies in Copilot settings. GitHub recommends verifying model availability in individual Copilot settings and confirming policy enablement for replacement models, which will then appear in the model selector in VS Code and github.com.
No manual intervention is required to remove the deprecated models from systems. The transition is designed to be seamless for users with supported alternatives enabled. GitHub Enterprise customers seeking assistance during the migration can contact their account managers.
