OpenAI's Astra becomes first model to hit 'Critical' cyber threshold after finding zero-days
MarcoFigueroa · x · 2026-09-03
Per SecurityWeek, OpenAI says its newest model Astra is the first of its models to reach the 'Critical' cybersecurity capability level under its Preparedness Framework.
- What Critical means: the model can independently find and exploit zero-day vulnerabilities across many well-defended systems, or run a complete cyberattack on a hardened target from a high-level instruction; extra safeguards are required before release
- Benchmarks: Astra scored a perfect ExploitBench (turning known vulns into working exploits) and demonstrated zero-day discovery in a separate evaluation
- Commenter MarcoFigueroa notes that AI-found zero-days went from controversial to industry norm in about a year
