About GPT-6 Astra
Astra is the top of OpenAI’s GPT-6 family and the model OpenAI calls its most capable. Its launch numbers are strongest in maths and science — 96.0% on GPQA Diamond and 97.6% on FrontierMath Tier 4 — and in operating software, with 92.7% on ScreenSpot-Pro. OpenAI says it gets there with roughly 70% fewer tokens than GPT-5.6 Sol on the same tasks.
It is also the first model OpenAI has rated “Critical” for cybersecurity, and it went to defensive-security programmes first. It always reasons, from low to max effort. A week after it launched, GPT-6.1 Sol came within a point or two of it on most agent tests at a fraction of the price, so try Sol before you pay for Astra.
What is GPT-6 Astra good for?
- Advanced maths and science problems.
- The hardest end-to-end agent tasks.
- Operating software through its interface — reading screens, clicking, typing.
- Problems where a cheaper model’s answer is not good enough.
Where to be careful
- Slower to answer than the Sol and Luna tiers, and it cannot be told not to reason.
- On Humanity’s Last Exam it trails Claude Fable 5.1, 57.2% against 65.0%.
- GPT-6.1 Sol matches it on many agent tasks at a much lower rate. Test both.
