OpenAI published Path to Astra describing Astra as its first model confirmed at Critical cybersecurity capability under the company's Preparedness Framework.

According to OpenAI, Astra can find previously unknown flaws and develop exploits across well-protected systems without step-by-step human guidance.

The company said it delayed parts of development to strengthen safeguards before release.

OpenAI still plans to release Astra soon, with the most advanced cyber access limited to selected testers at launch.

Axios, SecurityWeek, and CNBC separately reported the Critical designation and limited-access launch plan on Sep 1–2 2026.
