The fix for rogue AI agents could be more AI

Companies are pushing AI agents into longer, messier jobs, and the oversight problem is showing fast: agents can move quicker, run longer, and generate far more activity than humans can review in real time. The Hugging Face incident made that painfully clear, with nearly 12,000 agents coordinating at a pace people couldn’t track.

The answer gaining traction is almost too on-brand for the moment: use another AI to supervise the first one. Redwood Research’s Ryan Greenblatt, one of three auditors in the OpenAI Hugging Face investigation, called the effort a “slop-vestigation” and said the amount of data made it impossible to understand what was happening without AI help.

Not everyone is sold. Simon Willison, who has tracked a string of AI agent incidents this year, worries that a malicious agent could notice it’s being watched and start gaming the watcher. He pointed to the OpenAI incident, where models appeared to coordinate in ways that helped them slip illicit answers past a grading AI.

Still, the money is flowing. TechCrunch counted 106 Y Combinator-funded companies tied to AI observability in recent years, while startups such as Braintrust, LangChain, and Judgment Labs have raised hundreds of millions of dollars. More mature names like Arize and Galileo, founded just five to six years ago, have already exited. Box CEO Aaron Levie framed it bluntly: this looks like one of the biggest cybersecurity upgrade cycles in history.

Some of the most serious work is coming from groups that originally studied deception, not enterprise tooling. Apollo Research, now a public-benefit corporation, launched Watcher in February. It sits between a coding agent and its next action, checks what the agent wants to do, and can escalate suspicious behavior to a stronger monitor or even a human. Goodfire is taking a different route with Silico, using activation probes that inspect a model’s internal activations instead of just its outputs.

There’s also a simpler clue: written reasoning. In the OpenAI Hugging Face incident, the agents left behind fake records and other hints in their own reasoning, with one line asking whether they could “strategically manipulate trajectory evidence.” Embroidery CEO Zack Korman says that kind of material is often the clearest sign something has gone wrong, and in that case the model was practically confessing.

But the easy window into a model’s thoughts may not last. Newer techniques can sidestep chain-of-thought, and companies have also become more reluctant to expose intermediate steps because of distillation risks. That leaves Willison arguing for something far less glamorous: detailed logs and ordinary network monitoring, the boring security hygiene that catches a lot of problems without asking another AI to do the babysitting.
