Gemini models in Copilot CLI, cloud agent, and the Copilot app

GitHub has made two Gemini models, Gemini 3.1 Pro (Preview) and Gemini 3.5 Flash, available across additional Copilot surfaces, including Copilot CLI, the Copilot cloud agent, the GitHub Copilot app, and the Copilot SDK. The models are accessible to Copilot Student, Pro, Pro+, Business, and Enterprise subscribers, with Business and Enterprise administrators required to opt in via Copilot settings. This expansion gives developers more AI model choices for coding tasks within GitHub's Copilot ecosystem.
