President Donald Trump said he would postpone the release of an executive order that would set up a 90-day testing and vetting regime for frontier AI models, hours before the White House was set to publicly announce the signing. Speaking to reporters in the Oval Office Thursday, Trump said he opted to delay the order “because I didn’t like certain aspects of it” and expressed concerns that it could harm U.S. AI industry competition with countries like China. According to multiple sources, a draft version of the order circulating in the last 24 hours would have set up a voluntary testing regime between the U.S. federal government and frontier AI companies that would allow the government to study new models for 90 days before they’re publicly released. In addition to the government, the draft order would also facilitate access to the models for cybersecurity testers in critical infrastructure sectors, like finance and healthcare.
