OpenAI says a 250+ person internal effort used its cyber models to find and fix critical vulnerabilities across hundreds of its own systems—bugs it might never have caught otherwise.
The company is publishing the architecture, learnings, and a practical playbook so others can build a "Defense Factory": a continuous loop where AI agents discover vulnerabilities, validate them, and verify that fixes work, exploiting the defenders' window.
