OpenAI says Astra is its first Critical cybersecurity model

OpenAI says Astra is the first model it has designated at the Critical cybersecurity capability threshold under its Preparedness Framework. The company says Astra can find unknown flaws and build exploits across hardened systems without step-by-step human guidance, and that stronger safeguards plus limited alpha access come with the release. Capability numbers and safeguard scores are OpenAI's own claims. Separately, Lauren shipped Dr Eggbot v0.2 with routine health checks for Grok Bots.
