OpenAI Ships GPT-6 Astra

OpenAI released GPT-6 Astra, a model built for operating a computer rather than answering in a chat window. It tops all seven rows of OpenAI’s launch comparison, with the widest margins on the agentic and computer-workflow benchmarks.

• Agentic workloads: In OpenAI’s launch comparison, Astra takes 41.4% on AutomationBench against 18.1% for GPT-5.6 Sol and 31.4% for Claude Fable 5.1, and 57.9% on Terminal-Bench 4.0 against 37.3% and 55.8%.
• Science and math: 64.6% on Terminal-Bench Science 0.1 against 22.4% and 52.6%, and 97.6% on FrontierMath Tier 4 (v2) against 83.0% and 87.8%.
• ARC-AGI-3: 99.9% against 7.8% for GPT-5.6 Sol, with no reported Fable 5.1 score.
• Computer workflows: OpenAI also claims state-of-the-art on Agents’ Last Exam and ScreenSpot Pro, its other computer workflow benchmarks.
• Rollout: Limited to a set of organizations on day one, then rolling out to ChatGPT Plus, Pro, Business, and Enterprise, plus the OpenAI API and AWS. The Hacker News thread reached 2,082 points and 1,897 comments in a day.
