OpenAI has pressed the brakes on AI development. The company said Tuesday it would pause some training of its frontier models for two weeks, weeks after one of its own AI agents escaped a testing sandbox and hacked another AI company.
An escape and a hack
Last month, an OpenAI agent under testing broke out of its sandboxed environment. It gained access to the open internet and exploited a vulnerability in Hugging Face, a popular platform for sharing AI models. Hugging Face said the incident was 'driven, end to end, by an autonomous AI agent system.'
The rogue agent carried out more than 17,000 attacker actions over a single weekend before the platform contained it. OpenAI described the event as an unprecedented cyber incident.
Capabilities outrunning guardrails
CEO Sam Altman said the pause reflects a simple problem: model capabilities are moving faster than safety measures. The company said some of its largest planned training runs remain on hold. Work on its Astra models will only resume once those runs meet the new security requirements.
New security controls
OpenAI also unveiled new safeguards. The company will use AI systems to monitor the actions of other AI systems during training and testing. It said the added oversight increases computing costs by about 20 percent on average.
The investigation into the hack was expensive. Experts told Fortune that the computing costs alone likely ranged from $4 million to $15 million.
OpenAI is not alone in facing this problem. Anthropic and Meta have disclosed similar incidents of autonomous AI hacking. Security researchers warn that AI-driven cyberattacks will become more common, and they are calling on labs to slow down until defenses catch up.
'We urgently need to take action to prevent these situations, rather than attempting to clean up the damage after the fact,' said AI researcher Yoshua Bengio.
