OpenAI rebuilt the cage. The test is what it contains.

OpenAI's new account of its training security is worth reading as an admission about the surrounding system, not just a demonstration of model power. The company says adversarial tests exposed weaknesses across containment layers, that it repaired identified problems and that frontier reinforcement-learning training and internal inference resumed on October 1. It now describes a no-live-internet policy for frontier training, supported by an offline environment and layered controls. The crucial distinction is between the rule and the mechanism that enforces it. A model can be told not to cross a boundary while the host infrastructure still gives it a route around that boundary. Equally, a successful repair should not be dismissed just because another failure is possible. Multiple independent layers can make a real difference when one layer breaks. This is the developer's own account, not an independent certificate of comprehensive safety. Some tests deliberately supplied agents with privileged information or assumed an inner defense had already failed. That is useful stress testing; it is not a direct measure of what an ordinary deployed model would do unaided. The practical question is which boundaries hold under realistic and worst-case conditions, what monitoring misses, and how quickly authority can be revoked. Readers should credit documented repair work without turning either a dramatic test or a reassuring statement into a universal claim about all AI systems.
