GitHub Copilot: GPT-6.1 Sol Now Generally Available

GitHub CopilotView original changelog

GitHub made OpenAI's GPT-6.1 Sol generally available in GitHub Copilot. The model is aimed at agentic coding and terminal workflows, with strong multistep coding performance and noticeably fewer tokens and steps than earlier models. It is rolling out gradually to Copilot Pro+, Max, Business, and Enterprise users across most Copilot surfaces, billed at provider list pricing under usage-based billing.

Key Takeaways

  • GPT-6.1 Sol is now generally available in GitHub Copilot as of September 29, 2026, following the GPT-6 Sol release a week earlier.
  • The model is tuned for agentic coding and terminal workflows, with strong multistep coding performance.
  • GitHub says it uses noticeably fewer tokens and steps than earlier models, which matters for long autonomous runs.
  • It is available on Pro+, Max, Business, and Enterprise plans, with a gradual rollout so some users may not see it right away.
  • The model shows up in the picker across VS Code, Visual Studio, Copilot CLI, the coding agent, GitHub.com, Mobile, JetBrains, Xcode, and Eclipse.
  • Pricing follows provider list pricing under usage-based billing, and admins can allow or block it via the Copilot model policy, where new models are on by default.

GPT-6.1 Sol Arrives in GitHub Copilot

GitHub announced on September 29, 2026 that OpenAI's GPT-6.1 Sol is now generally available in GitHub Copilot. According to GitHub, the model excels at agentic coding and terminal workflows, delivering strong multistep coding performance while using noticeably fewer tokens and steps than earlier models. For developers who lean on Copilot to carry out longer, autonomous tasks, that combination of capability and efficiency is the main draw.

Where It Is Available

GPT-6.1 Sol can be selected from the model picker across a wide range of Copilot surfaces: Visual Studio Code, Visual Studio, Copilot CLI, the GitHub Copilot coding agent, GitHub.com, GitHub Mobile on iOS and Android, JetBrains IDEs, Xcode, and Eclipse. Access is limited to paid tiers, specifically Copilot Pro+, Max, Business, and Enterprise. GitHub notes that the rollout is gradual, so the model may not appear for every user immediately.

Pricing and Billing

The model is billed at provider list pricing under Copilot's usage-based billing. Detailed rates are published in GitHub's models and pricing documentation, so teams planning heavy agentic use can estimate costs before switching their default model.

Administrator Controls

Copilot Business and Enterprise administrators manage access through the model policy in Copilot settings. New models are enabled automatically unless an administrator has turned off the global default or explicitly disabled this specific model. Organizations that want tighter control over which models developers can use should review that policy before the rollout reaches their users.

Feedback

GitHub invited developers to share feedback on the model through GitHub Community discussions.
