Key points

  1. GitHub’s September 4 release identifies GPT-6 Astra as generally available in Copilot.
  2. GPT-6 Astra is a general-purpose model from OpenAI.
  3. GitHub describes its intended uses as long-horizon autonomous coding and agentic tasks.

Why it matters

Teams using Copilot can consider Astra for coding work that requires sustained execution across multiple steps. Its stated design goal supports a targeted trial, but does not establish reliability on a team’s own repositories.

What to watch

Check plan eligibility and usage limits, then look for reproducible results on extended coding tasks, including completion rates and required human intervention.
