Upcoming deprecation of Gemini 2.5 Pro and Gemini 3 Flash

We will deprecate Gemini 2.5 Pro and Gemini 3 Flash across all GitHub Copilot experiences (including Copilot Chat, inline edits, ask and agent modes, and code completions) on July 31st, 2026:

Model	Deprecation date	Suggested alternative
Gemini 2.5 Pro	7-31-2026	Gemini 3.1 Pro
Gemini 3 Flash	7-31-2026	Gemini 3.5 Flash

Please update your workflows and integrations to use the supported models before these dates. Copilot Enterprise administrators may need to enable access to the alternative models through their model policies in Copilot settings. As an administrator, you can verify availability by checking your individual Copilot settings and confirming that the policy is enabled for the specific model. Once enabled, you’ll see the model in the Copilot Chat model selector in VS Code and on github.com. No action is required to remove the older models once they have been deprecated.

GitHub Enterprise customers with questions or concerns are encouraged to reach out to their account manager for further assistance.
