GPT-6 Astra now available in GitHub Copilot
GitHub said on 4 Sep 2026 that OpenAI’s GPT-6 Astra is generally available in GitHub Copilot for Pro+, Max, Business, and Enterprise users across VS Code, Visual Studio, CLI, coding agent, Copilot app, github.com, Mobile, JetBrains, Xcode, and Eclipse (gradual rollout). In GitHub’s internal testing it stood out for planning and validating as it works, with stronger long-horizon coding and fewer steps than prior OpenAI models in Copilot. It is billed at provider list pricing under usage-based billing; Business/Enterprise admins manage access via Copilot model policy (new models on by default unless global default enablement is off or this model is blocked). This is GitHub Copilot availability, not the OpenAI GPT-6 Astra launch flash, and not Microsoft 365 Copilot.
