OpenAI's GPT-6 Astra is now generally available across GitHub Copilot, built for long-horizon autonomous coding and agentic tasks. GitHub's internal testing highlights it plans and validates as it goes, batches diagnosis with verification, and independently confirms results — stronger performance on long-horizon coding with fewer steps than prior OpenAI models. Available to Pro+, Max, Business and Enterprise plans across VS Code, JetBrains, Xcode and more, billed at provider list pricing.
