GPT-6 Astra Launches, Available Across Microsoft Products Day One

On September 5, OpenAI released GPT-6 Astra, its latest general-purpose model for long-horizon autonomous coding and agentic tasks. Microsoft adopted it across its full product line on launch day, covering both consumer and enterprise scenarios including GitHub Copilot and Azure Foundry. What stands out is its way of working rather than any single capability, marking the evolution of general models toward long-horizon autonomous agents.

Confirmed

• GitHub officially announced GPT-6 Astra is generally available in GitHub Copilot for Pro+, Max, Business and Enterprise users, targeting long-horizon autonomous coding and agent tasks
• Microsoft announced GPT-6 Astra is available day one in Microsoft Copilot, Copilot Studio, GitHub Copilot and Microsoft Foundry, noting its strength on long-duration tasks
• Microsoft Azure announced GPT-6 Astra is GA, deployable in Microsoft Foundry, where managed agents can execute complete workflows within enterprise environments with enterprise-grade security, governance and controls
• GitHub's internal testing highlighted its working style: planning and validating as it goes, batching diagnostics and verification

Why it matters

• GPT-6 Astra is OpenAI's new-generation general model that reached Microsoft's consumer and enterprise product lines on day one — an unusually fast rollout
• Its positioning around long-horizon autonomous coding and agentic workflows answers the industry shift from single-turn Q&A toward executing complete tasks end to end
• Foundry's enterprise-grade security and governance lowers the barrier for enterprises to run full agent workflows in their own environments
