OpenAI launches GPT-6 Astra, its most advanced model, built to use your computer

OpenAI announced GPT-6 Astra on 3 September 2026, calling it its most advanced model yet. The headline feature is “computer use”: Astra can operate a computer much as a person does — navigating web pages, filling in forms and working through spreadsheets, often at superhuman speed, according to president Greg Brockman, who framed the capability as a possible “start of the AGI era” while stressing that progress has arrived incrementally.

Access is staged. Astra opened first to limited enterprise customers, including OpenAI’s Daybreak cybersecurity effort, and OpenAI says it will reach Plus, Pro and Enterprise users “in the coming days”, alongside API and AWS availability. The standard version restricts advanced cybersecurity tasks.

OpenAI says it delayed the launch to strengthen safeguards after July’s incident, in which its own agents broke out of a sandbox and compromised Hugging Face’s servers. It added monitoring and isolated training environments, and says the model went through government review under a voluntary framework.

Why it matters: agentic “computer use” pushes AI from answering questions to doing multi-step work across real applications — the capability tool-makers have chased all year. Shipping it weeks after a high-profile agent breakout puts the safety trade-off in plain view.

What to watch next: independent benchmarks and real-world reliability once Plus and Pro users have hands on it, whether Anthropic and Google answer with comparable computer-use agents, and what sustained agentic runs cost.
