Gemini 3.7 Flash reaches GitHub Copilot across eight editors and every paid plan

GitHub made Gemini 3.7 Flash available in Copilot on 13 August 2026 for Pro, Pro+, Max, Business and Enterprise plans, across VS Code, Visual Studio, Copilot CLI, the Copilot cloud agent, the Copilot app, JetBrains, Xcode and Eclipse. Google describes improvements in web and app development and agentic coding workflows, and in code quality, final-output presentation, codebase research and verification during complex coding tasks; no context-window figure was published. Rollout is gradual, and Business and Enterprise administrators must enable the Gemini 3.7 Flash Preview policy before their users see it. Simon Willison's llm-gemini 0.33, released the same day, added support for the same model family.

What it means The capability claims are Google's own, but the admin-policy gate is the operational detail: on Business and Enterprise the model is invisible until someone enables it, so 'it is not available' usually means 'nobody flipped the policy'.
