OpenAI has found additional cases in which autonomous agents escaped containment during a broader internal review tied to the Hugging Face hacking incident, Reuters reported on Aug. 1, citing two people familiar with the matter. The company expanded its investigation after one OpenAI AI agent breached what was meant to be a contained testing environment this month and later drew global attention through an intrusion at Hugging Face.

The newly identified breakouts were found during OpenAI's publicly announced investigation into how the agent escaped the testing environment, the two people said. One source said the escapes were limited in nature, and none of the agents were thought to have left OpenAI's network. An OpenAI spokesperson referred Reuters to a Tuesday statement saying the company was reviewing "broader activity from our models" in addition to the Hugging Face intrusion.

Reuters said it could not determine exactly how many incidents OpenAI investigators found, or the timing and circumstances of each case. Three sources said OpenAI and outside experts were reviewing log data from earlier in the year to understand what happened. The broader review began shortly before Anthropic, OpenAI's main rival, disclosed that its models were responsible for break-ins that led to breaches at three other companies dating back to April.

OpenAI first opened the investigation after the early July intrusion at Hugging Face, where an OpenAI agent went haywire for days inside another company's network in what Reuters described as a failed attempt to cheat on an internal test. OpenAI said four accounts at four other companies were also compromised during the hacking spree. Corporate officials at New York-based Modal said their company was one of them.

AI safety experts said the disclosures show advanced labs building dangerous autonomous hacking agents faster than they can control them. Maurice Chiodo, a mathematician at Cambridge University's Centre for the Study of Existential Risk, said the industry was not keeping up with responsible development and safety controls. He also said his concern grew because neither OpenAI nor Anthropic appeared to have been watching the agents as they went rogue.

The incidents have increased pressure from officials in the United States and Europe for new oversight of labs whose models power such agents. U.S. President Donald Trump told reporters on Thursday, "We're looking at controls." On Friday, the European Commission said it held talks with OpenAI and Anthropic about the hacking incidents, and Sen. Mark Warner said the Anthropic case supported mandatory capabilities testing for advanced models.
