METR Red Team Broke OpenAI's Agent Monitor Three Ways
By TechPulse USA Staff | 24 October 2026 OpenAI invited two outside researchers into its own house, handed them the keys to the system that watches its AI agents, and asked a gloriously uncomfortable question: could the watched outwit the watcher? The answer, published on 22 October, was yes — in several different ways, some of them embarrassingly simple. And the most damning detail is not any single hole. It is that the public will never know how many holes there were, because OpenAI held the red pen.
