US President Donald Trump released a one-page artificial intelligence (AI) accord on Sept. 29 that he said had been signed by him and technology executives he met in Washington. Posted on Truth Social, the document calls for four layers of corporate controls: independent external assessments, board-level oversight, internal monitoring of AI models during training and deployment, and an internal team responsible for checking that controls operate as intended. The document was signed by Trump and the bosses of Google, Anthropic, Meta, OpenAI, social media platform X and Nvidia. The White House said the measures could eventually be codified into laws or regulations and described audits and controls as critical to a safe future. Participating companies will meet regularly to establish safety standards and best practices.
