GitHub Copilot: GPT-6.1 Terra Now Generally Available

GitHub CopilotView original changelog

GitHub made OpenAI's GPT-6.1 Terra generally available in GitHub Copilot, aimed at everyday agentic coding and terminal work at a lower cost than GPT-6.1 Sol. In early testing, GitHub reports that the model solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra, and that it works in focused, consolidated steps on well-scoped tasks. It is billed at provider list pricing under usage-based billing and is rolling out gradually across Copilot Pro, Pro+, Max, Business and Enterprise.

Key Takeaways

  • GPT-6.1 Terra is now generally available in GitHub Copilot, positioned for everyday agentic coding and terminal work.
  • It costs less than GPT-6.1 Sol, making it the cheaper option within the GPT-6.1 family.
  • In GitHub's early testing, it solved noticeably more terminal and C# tasks than GPT-5.6 Terra.
  • The model tends to work in focused, consolidated steps on well-scoped tasks, which fits routine features and bug fixes.
  • It is billed at provider list pricing under usage-based billing, and is available on Pro, Pro+, Max, Business and Enterprise.
  • It appears in the model picker across ten surfaces, from VS Code and JetBrains to Xcode, Eclipse and GitHub Mobile, with a gradual rollout and admin control through model policy.

A Lower-Cost GPT-6.1 Model for Everyday Agentic Work

GitHub made GPT-6.1 Terra, OpenAI's newest model in the Terra tier, generally available in GitHub Copilot. The model is aimed at everyday agentic coding and terminal work, and it sits below GPT-6.1 Sol on cost. That makes it a natural default for developers who want a capable agentic model without paying for the top of the GPT-6.1 line.

Early Results

GitHub reports that in early testing GPT-6.1 Terra solved noticeably more terminal and C# coding tasks than GPT-5.6 Terra, the previous model in the same tier. GitHub also describes the model as working in focused, consolidated steps on well-scoped tasks, which suits routine feature work and bug fixes where a developer already knows what they want done.

Availability

GPT-6.1 Terra is available on Copilot Pro, Pro+, Max, Business and Enterprise plans. Developers can pick it in the model picker in:

  • Visual Studio Code
  • Visual Studio
  • Copilot CLI
  • The GitHub Copilot cloud agent
  • The GitHub Copilot app
  • github.com
  • GitHub Mobile (iOS and Android)
  • JetBrains IDEs
  • Xcode
  • Eclipse

The rollout is gradual, so developers who do not see the model yet should check back soon.

Pricing and Billing

The model is billed at provider list pricing under usage-based billing. GitHub points developers to its "Models and pricing for GitHub Copilot" documentation for the exact rates.

Admin Access

Enterprise and Business administrators manage access through the model policy in Copilot settings. Under default model enablement, new models are enabled automatically unless an administrator has turned off the global default or explicitly disabled this specific model.
