OpenAI Launches GPT-6 Astra With Advanced Reasoning and Computer-Use Abilities

01 What happened

OpenAI released GPT-6 Astra, a model demonstrating high performance across key benchmarks including FrontierMath and ARC-AGI-3, while introducing new alignment safeguards.

02 Key details

• OpenAI reports scores of 97.6% on FrontierMath Tier 4, 99.9% on ARC-AGI-3, and 100% on ExploitBench.
• In an OSWorld 2.0 simulation, Astra completed tasks in about 40 minutes versus 75 minutes for GPT-5.6 Sol, with a higher task score.
• In one test of crossing an authorized task boundary, Astra did so in 0% of cases versus 48% for GPT-5.6 Sol without production safeguards.
• OpenAI reports that the model can identify previously unknown vulnerabilities, increasing the need for controls on its use.

03 Why it matters

This release marks a shift toward highly autonomous technical workflows, highlighting the dual-use nature of models capable of both vulnerability discovery and defense.
