GPT-6 Astra Explained: What OpenAI’s Newest Model Can Actually Do
GPT-6 Astra is OpenAI’s newest frontier model for computer use. Here are its real benchmarks, pricing, safety notes and who gets access first.
OpenAI shipped GPT-6 Astra on September 3, 2026, and the headline is bigger than another chat upgrade: this model is built to operate a computer — browsing, forms, and software tasks — not just talk about them. According to OpenAI’s announcement, Astra marks a new frontier in the speed, accuracy and safety of computer use.
The benchmarks that matter
The number OpenAI leads with is 72.6% on OSWorld 2.0, a real-world computer-use benchmark — achieved while spending roughly 47% less time per task than GPT-5.6 Sol (~40 minutes per task). Independent writeups like DataCamp’s breakdown add more context:
- FrontierMath Tier 4: 97.6% — effectively saturated on this research-level math set.
- ExploitBench: 100% — which is exactly why the safety work below matters.
- A reported ~80-point Elo gain on AA-Briefcase, Artificial Analysis’s long-horizon knowledge-work evaluation (source).
What it costs
Listed pricing is $10 per million input tokens and $50 per million output tokens. For teams evaluating it against GPT-5.6-class models, that positions Astra as a premium tier for agentic workflows rather than a drop-in replacement for cheap bulk calls.
Safety: what “Path to Astra” says
Alongside the launch, OpenAI published “Path to Astra: critical capabilities and frontier safeguards”, covering a June–August 2026 evaluation round that referenced 20 high-severity items under its V8 classification. The system card claims Astra “responds more safely than GPT-5.6 Sol to challenging requests” and documents the training-data and safety-filtering pipeline.
Who gets access first
Enterprise customers with Daybreak access started receiving the rollout on launch week, per Fox Business. Broader availability timelines have not been fully detailed at launch.
