OpenAI found more cases where autonomous agents escaped testing environments, expanding a probe into a Hugging Face hack that drew global attention this month.
OpenAI has uncovered additional instances where autonomous agents broke out of their testing environments, as the company expands an investigation into a hacking incident at Hugging Face that became public this month, two people familiar with the matter said Friday. The new breakouts surfaced during the company's probe into how one of its agents escaped a contained testing environment earlier in July, the two people said. OpenAI is now examining those cases as well.
One of the sources said the escapes were limited and that none of the agents were believed to have left OpenAI's network. An OpenAI spokesperson referred to a Tuesday statement saying the company was reviewing "broader activity from our models" beyond the Hugging Face intrusion.
The discovery of additional rogue behavior, even if contained, could fuel calls for regulation coming from the White House and elsewhere, the people said. The expanded investigation began shortly before OpenAI's primary rival, Anthropic, disclosed that its own models were responsible for a series of break-ins at three other companies dating back to April, according to the two sources and a third person familiar with the matter. The earlier breakouts at OpenAI have not previously been reported.
AI safety experts said the disclosures paint a picture of labs whose ability to develop dangerous autonomous hacking agents outstrips their ability to control them.
"We have a whole industry where the people designing, developing and putting out these tools aren't keeping up themselves to responsibly develop these things and keep them safe," said Maurice Chiodo, a mathematician at Cambridge University's Centre for the Study of Existential Risk.
Reuters could not establish how many incidents OpenAI investigators found, or the timing and circumstances. The three sources said OpenAI and outside experts were examining log data from earlier in the year to understand what happened.
OpenAI first launched the investigation after the early July intrusion at Hugging Face, where an OpenAI agent went haywire inside another company's network in a botched effort to cheat on an internal test. As part of that hacking spree, OpenAI said four accounts at four other companies were compromised. One was New York-based Modal, corporate officials there said.
Chiodo said his concerns grew from indications that neither OpenAI nor Anthropic were watching the agents as they went rogue. Reuters has reported that OpenAI realized its agent had broken into Hugging Face only after the company contained the hack, contacted the FBI and went public. OpenAI has said the Reuters account contained inaccuracies but has not responded when asked what those were.
In a Thursday statement disclosing how its own agents hacked victims online, Anthropic suggested it had not been watching them in real time, saying that "real-time monitoring of the evaluation logs would have helped to surface the problem sooner." Chiodo said that pointed to a lack of proper scrutiny. "It seems like they weren't even looking," he said.
Anthropic said it did have real-time monitoring in place, but that it had not been used "for this threat surface" due to a misunderstanding between the AI company and a partner.
The widening scope of the runaway AI agents story has heightened pressure from lawmakers and officials across the United States and Europe to push for new government oversight. "We're looking at controls," President Donald Trump told reporters Thursday. On Friday, the European Commission said it held talks with OpenAI and Anthropic over the hacking incidents.
Senator Mark Warner, the top Democrat on the Senate Intelligence Committee, said Friday that the Anthropic incident "tells me that legislatively we're correct to require mandatory capabilities testing of these advanced models."
