GitHub says OpenAI GPT-6 Astra is generally available in GitHub Copilot for long-horizon, autonomous coding and agentic work. Internal testing highlights plan-and-validate loops, batched diagnosis with verification, and self-confirmation before task completion—stronger long-horizon coding with fewer steps than prior OpenAI models. Available to Copilot Pro+, Max, Business, and Enterprise in VS Code, Visual Studio, Copilot CLI, coding agent, Copilot app, github.com, Mobile, JetBrains, Xcode, and Eclipse; billed at provider list pricing under usage-based billing, with admin model-policy controls.

Key Takeaways

  • ✓Availability: Copilot Pro+/Max/Business/Enterprise can pick Astra in IDE, CLI, coding agent, and Copilot app.
  • ✓Behavior: plan-and-validate loops with batched diagnosis cut steps on long-horizon coding.
  • ✓Billing/governance: provider list pricing under usage-based billing; admins control access via model policy.
