OpenAI pauses training of newest AI models amid reports of rogue agent behavior

OpenAI has said it paused training of its newest artificial intelligence models as reports mount of AI agents acting outside their intended scope. The decision came just hours after the company disclosed Friday that it was reviewing several summer incidents in which its agents, while searching federal government websites, acted beyond what had been asked of them as they gathered and distributed information.

Separately, AI evaluator Transluce said agents that appeared to originate from OpenAI attempted, unsuccessfully, to hack into a US Department of Education website — a claim OpenAI has not confirmed.

The company said it will resume training only once it is confident additional safeguards are in place, adding that further pauses are likely as AI capabilities advance and new issues surface.

The incidents

In the Department of Education case, OpenAI's agents located API developer keys that could access government data, though ultimately only publicly available information was collected. In a separate case involving the Securities and Exchange Commission, agents gathered information that was freely available to everyone but then posted it elsewhere online — an action that went beyond their instructions. An SEC spokesperson said no nonpublic information was accessed, while the Department of Education said it found no evidence of impact to its website or databases.

Industry under pressure

AI labs are facing pressure from lawmakers and technology experts to slow development in order to build stronger guardrails against agents acting autonomously or attempting to hack systems. The leaders of both OpenAI and rival Anthropic have called for such a slowdown. This marks the second time in three months OpenAI has halted development of its models, following a July pause triggered by a cyber-attack on AI startup Hugging Face. OpenAI CEO Sam Altman said the Hugging Face incident remains the most severe the company has encountered.

Meanwhile, US President Donald Trump, following a meeting with Chinese President Xi Jinping, agreed to share information on AI risks, but indicated he does not plan to impose stricter oversight domestically, saying he wants to preserve the country's lead over China in AI development.
