OpenAI Plans to Release First Model to Meet Its ‘Critical' Cybersecurity Threshold
OpenAI has confirmed that its upcoming model Astra meets the Critical cybersecurity threshold under its Preparedness Framework. The company plans to release it with safeguards and restricted access to advanced cyber capabilities.
Astra is the first model OpenAI has placed at that tier. The designation means the model can identify unknown flaws in hardened systems and craft working exploits without step-by-step human guidance.
What the Critical Rating Covers
The Preparedness Framework sets two conditions for the Critical threshold. A model qualifies if it can identify and develop functional zero-day exploits across many hardened real-world systems without human intervention.
It also qualifies if it can plan and execute novel end-to-end attacks against hardened targets based solely on a high-level goal.
Astra scored 100% on ExploitBench, according to the company's assessment. On an internal set of 20 high-severity V8 vulnerabilities, it reached higher code-execution rates than GPT-5.6 Sol while using far fewer tokens.
