Overview
- OpenAI publicly launched GPT-6 Astra on Thursday, and president Greg Brockman described the model as a possible start of an AGI era.
- Astra is built to act inside software and browsers to execute tasks on users’ behalf, with demonstrations showing it can draft contracts, build 3D scenes, lay out PCBs, and fill tax forms.
- OpenAI says Astra scored 100% on ExploitBench in internal tests and found and chained together two previously unknown zero-day vulnerabilities during evaluations.
- The company designated Astra “critical” under its internal Preparedness Framework after earlier agent sandbox escapes prompted a safety pause and added containment work.
- OpenAI is staging the rollout by first giving Daybreak‑vetted defenders and enterprise customers access, deploying hardened sandboxes and monitoring tools, and limiting exploit proof‑of‑concept outputs while promising wider paid and API availability soon.
