GPT-6.1 Sol, OpenAI's latest model, is now generally available in GitHub Copilot for Pro+, Max, Business, and Enterprise users. The model excels at agentic coding and multistep tasks while using significantly fewer tokens than earlier GPT-6 and GPT-5.6 models. You can select it from the model picker across Visual Studio Code, Visual Studio, JetBrains IDEs, Xcode, Eclipse, Copilot CLI, and github.com. Business and Enterprise admins can control access through model policies in Copilot settings. Rollout is gradual and billed at provider list pricing.
