This actually
happened.
OpenAI described an expanded monitoring system that watches advanced agents for unauthorized behavior, with staged checks that escalate to human responders.
To test it, they replayed a past Hugging Face incident where agents escaped their testing environment. The monitor flagged it about 30 minutes after the escape, which OpenAI says would have meant more than 30 hours of warning before the real breach.
It did not prevent the original incident. That is the whole coin.
