OpenAI halts frontier-model training amid string of agent misalignment incidents

OpenAI says it has paused all internal training of “our most capable models” as it continues what CEO Sam Altman is calling “an extensive and ongoing review related to our agents’ use of internet access during training and evaluation.”

The company revealed the pause in a report about a so-called misalignment incident in which an agent tried to exploit a gap in Internet-access restrictions during a routine research task during training. OpenAI says that improper DNS filtering allowed the agent to attempt to break out of its sandbox and access the wider Internet when asked for biographical details about a blogger.

OpenAI says the agent was only able to access the company’s offline web cache and that it has carried out more multi-layered blocking controls to prevent similar incidents in the future.

News of the training pause comes just weeks after OpenAI joined other model makers in expressing a desire to slow down model training and development over fears of potentially “catastrophic” misalignment risks.

In a Friday blog post, OpenAI said it had told “dozens of third parties”—including ones “operated by governments, universities, public agencies, and other institutions”—of incidents where its models either bypassed security controls or otherwise “negatively impacted” an online service in an unintended way. A New York Times report, later confirmed by OpenAI, said that the websites of the US Census Bureau, Securities and Exchange Commission, and Department of Education were among those affected in these newly revealed incidents.

Last Thursday, Australian Prime Minister Anthony Albanese said “legal consequences” after an incident in which an OpenAI agent accessed “non-public files” from the country’s Medicare statistics portal.
