Key Takeaways

  • Gemini 4 Carbon is now generally available in GitHub Copilot, giving developers another frontier model choice from Google.
  • GitHub positions the model for complex coding, agentic and reasoning tasks, with an emphasis on secure code generation.
  • Access covers Copilot Pro+, Max, Business and Enterprise plans, so Free and Pro users do not get it.
  • The model shows up in the picker across VS Code, Visual Studio, Copilot CLI, the Copilot app, github.com, GitHub Mobile, JetBrains, Xcode and Eclipse.
  • Usage is billed at the provider's list price under usage-based billing, so heavier use directly affects cost.
  • Rollout is gradual, and Business and Enterprise admins can control availability through the model policy in Copilot settings.

A New Google Model in the Copilot Model Picker

GitHub made Google's Gemini 4 Carbon generally available in GitHub Copilot on November 10, 2026. Google's latest model targets complex coding, agentic and reasoning tasks, and GitHub highlights its emphasis on secure code generation. It adds another frontier option for developers who like to choose a model per task instead of relying on a single default.

Where and How to Use It

Gemini 4 Carbon is selectable from the model picker across a wide range of Copilot surfaces. These include Visual Studio Code, Visual Studio, Copilot CLI, the Copilot coding agent, the Copilot app, github.com, GitHub Mobile on iOS and Android, JetBrains IDEs, Xcode and Eclipse. Because the rollout is gradual, some users may not see the model in their picker right away.

Plans and Pricing

The model is available to users on Copilot Pro+, Max, Business and Enterprise plans. It is billed at the provider's list price under usage-based billing, so the cost of a session depends on how much the model is used. GitHub's models and pricing documentation lists the specific rates.

Access for Business and Enterprise

Business and Enterprise administrators control access through the model policy in Copilot settings. Under default model enablement, new models are turned on automatically unless an administrator has disabled the global default or has disabled this model specifically. Users on those plans who cannot see Gemini 4 Carbon should check with their administrator.
