GitHub adds Gemini 4 Carbon to Copilot for four paid plans

Developers using GitHub Copilot are getting another model choice for complex coding and security-focused work, without leaving their existing development tools. GitHub announced general availability of Google’s Gemini 4 Carbon on November 10, 2026. Access covers four paid plans, but a gradual rollout means eligible subscribers may not see it immediately.

GitHub describes Carbon as designed for complex coding, reasoning and tasks involving AI agents, with an emphasis on secure code generation and security-focused work. That is the company’s description of the model’s intended role, not a quantified claim about how much safer its code will be.

From editors to mobile

The eligible subscriptions are Copilot Pro+, Max, Business and Enterprise. Users select Carbon through Copilot’s model picker, rather than through a separate Carbon application. GitHub lists availability across editor-based development, command-line work, its coding agent and apps:

• Editors and development environments: Visual Studio Code, Visual Studio, JetBrains IDEs, Xcode and Eclipse.
• Copilot tools: Copilot CLI, the command-line interface; GitHub Copilot coding agent; and the GitHub Copilot app.
• Web and mobile: github.com and GitHub Mobile on iOS and Android.

General availability does not mean simultaneous access across every eligible account. GitHub tells users who cannot yet find Carbon to check back as the rollout progresses. Subscription eligibility and the model’s appearance in the picker are therefore separate practical checks.

Team access and usage charges

Business and Enterprise administrators can manage Carbon through the model policy in Copilot settings. Those controls let an organization decide whether the model is available to its teams. An eligible workplace subscription alone does not override an administrator’s decision to disable it.

Carbon is billed at provider list pricing under usage-based billing. GitHub directs users to its Copilot models-and-pricing documentation for the details. The eligible-plan list establishes who can access the model; the billing terms separately establish how its use is charged.
