OpenAI Astra: All about the quantum math-solving model with critical hacking skills

Do you understand quantum parallel repetition? What about quantum complexity, lattice cryptography, or extremal combinatorics? The new OpenAI model Astra knows all about them.

On Aug.

1, OpenAI confirmed the existence of Astra , calling it "our next major model." And on Sept.

1, OpenAI confirmed in a blog post that Astra has reached a "critical" cyber threat level, but that it will also be "available soon." For safety reasons, the company plans to restrict its most advanced cybersecurity capabilities to a closed group of select testing partners.

Everything we know about the OpenAI Astra model We first learned about Astra when OpenAI announced that a mysterious new model had made some notable breakthroughs in research-level mathematics.

On Aug.

1, the ChatGPT-maker revealed that an internal model named Astra had solved 10 major open math problems, some of which had been unresolved for decades.

Then, on Aug.

7, OpenAI announced that Astra had developed such advanced cyber capabilities that new security controls were necessary and that some internal development work would be paused.

At the time, OpenAI said it couldn't "rule out critical cyber capabilities under our Preparedness Framework ," meaning the model could have existential-threat-level cybersecurity capabilities. (OpenAI's Preparedness Framework tracks risk levels in three categories: biological and chemical, cybersecurity, and AI self-improvement.) Finally, on Sept.

1, OpenAI confirmed that not only is Astra coming soon, but that it does, in fact, meet the "critical" threshold for cyber capabilities.

Previously, OpenAI deemed GPT-5.6-Sol a "high" cybersecurity risk, making Astra the first OpenAI model to be classified as a genuine "critical" risk.

"Under our Preparedness Framework, a model reaches the Critical cybersecurity threshold if it can identify and develop functional zero-day exploits of all severity levels in many hardened real-world critical systems without human intervention, or can devise and execute end-to-end novel strategies for cyberattacks against hardened targets given only a high level desired goal," an OpenAI blog post stated.

How is OpenAI tightening security around Astra? Until recently, the prospect of swarms of AI agents conducting relatively autonomous cyber attacks on critical infrastructure was mostly hypothetical.
