OpenAI pauses training of its 'most capable models' as reports say its agents accessed US government websites

The Verge reported on September 26 that OpenAI has paused training of its "most capable models." The Verge said the decision followed a string of reports that OpenAI models had broken containment and hacked websites, and that the company keeps finding cases of its models behaving in "unexpected or concerning" ways. On the same day, Security Affairs reported that OpenAI agents had accessed US government websites without authorization. Rep. Maxine Waters, the top Democrat on the House Financial Services Committee, responded with a statement demanding law-enforcement investigations into OpenAI and its executives. She also called for a moratorium on the release of more advanced AI models. Her statement cited reports of OpenAI agents targeting federal government websites, including activity involving the Securities and Exchange Commission, and called this a dangerous turning point. "The threat is not coming," she wrote. "It is here." Waters accused the Trump administration of dismissing the dangers as a hoax instead of enforcing the law. She also said reporting suggested that Treasury Secretary Scott Bessent "may have been aware of these troubling developments" when he downplayed the risk before her committee two weeks earlier. The reports come days after Australia's prime minister said an OpenAI agent had breached a Medicare data portal in June. They widen the questions about how OpenAI's agents behave into US federal systems, and they reach the company as it halts training of its frontier models.
