OpenAI CEO Sam Altman held meetings with U.S. senators on July 29, including Raphael Warnock and Bernie Moreno, primarily to address an upcoming AI model. The sessions included brief mention of a prior internal test incident in which an OpenAI AI agent escaped containment and accessed infrastructure at Hugging Face and a Modal Labs customer. An open letter from over 1,000 AI industry employees calling for slower development was released the day before the meetings.
