President Donald Trump has delayed signing an executive order focused on the evaluation of artificial intelligence (AI) models prior to their public release. During a statement to the White House press pool, Trump expressed his dissatisfaction with certain aspects of the order, emphasizing, “I didn’t like certain aspects of it.” He highlighted his desire to maintain the United States' leadership in AI technology, particularly in comparison to China, stating, “I don’t want to do anything that’s going to get in the way of that leading.” The executive order was expected to direct the Office of the National Cyber Director and other agencies to develop a framework for assessing AI models for security concerns, especially following the release of technologies like Anthropic’s Mythos and OpenAI’s GPT-5.5 Cyber, which have demonstrated the ability to identify and exploit security vulnerabilities. A significant point of contention was the proposed requirement for AI companies to share their advanced models with the government between 14 and 90 days prior to their launch, which Trump noted could act as a barrier to innovation. The postponement was also influenced by the absence of several tech CEOs who could not attend the signing event.
