OpenAI’s Astra/GPT-6 classified 'Critical' for cyber capability in company documentation

An internal Preparedness Framework designation and evidence release reportedly show Astra can find and exploit zero-day vulnerabilities; OpenAI has gated access and added monitoring that can interrupt tasks but warns about new failure modes.

In this brief: 2 sections 1 min read
    • Anavem reports OpenAI published a designation and system card saying Astra discovered two zero-day vulnerabilities in evaluation.
    • The 'Critical' threshold is defined by the model's ability to find and exploit novel security flaws across hardened systems without step-by-step human guidance.
    • OpenAI said it is in the process of disclosing those vulnerabilities to maintainers.
    • Astra is off by default in Business and Enterprise workspaces and requires deliberate admin enablement.
    • OpenAI's monitoring can slow, pause or stop tasks (including legitimate defensive work) when safety checks trigger.
    • API usage reportedly exposes new failure modes where long-running agent tasks may be stopped mid-run.
