OpenAI rates new GPT-6 Astra model 'Critical' for cybersecurity capability

OpenAI said GPT-6 Astra meets the Critical threshold for cybersecurity under its Preparedness Framework. The public version refuses advanced offensive tasks such as building proof-of-concept exploits, with less restricted access planned through its Daybreak programme for defenders.

What it means for business: security teams can expect stronger AI tools for defence, and attackers may gain them too; patching speed matters more.
