What changed

• Gemini 4 Carbon is now generally available in GitHub Copilot's model picker, positioned for complex coding, agentic and reasoning tasks with emphasis on secure code generation.
• Available to Copilot Pro+, Max, Business and Enterprise subscribers; not available on the Free or Pro tiers.
• Accessible across VS Code, Visual Studio, Copilot CLI, the Copilot coding agent, the Copilot app, github.com, GitHub Mobile, JetBrains IDEs, Xcode and Eclipse.

What it means for people who build with AI

Gemini 4 Carbon becomes a third frontier model from a major lab, alongside Claude and GPT, available in Copilot's picker. Its usage-based pricing, billed at provider list rates rather than Copilot's standard premium-request multiplier, gives developers a new cost and model-choice option when working inside Copilot.

Availability and rollout

The rollout is incremental, so availability may vary by region or account at first. Enterprise and Business admins can control access through Copilot's model policy, and new models like this one are enabled by default unless an admin turns them off.
