President Donald Trump and the heads of six of the world's biggest technology companies signed a voluntary agreement on Tuesday pledging new safety controls for advanced artificial intelligence, as the president also signed an executive order directing the federal government to stop calling the technology "artificial intelligence" and use "super intelligence" instead. The one-page document, titled the "White House Accord on Super Intelligence: Joint Commitment on Frontier Responsibilities," was posted by Trump on Truth Social following a lunch meeting at the White House with the tech leaders. Trump described the pact as "morally binding," acknowledging that it is not legally enforceable. The signatories are Sundar Pichai of Google, Dario Amodei of Anthropic, Mark Zuckerberg of Meta, Greg Brockman of OpenAI, Elon Musk of xAI, and Jensen Huang of Nvidia. Under the accord, the companies commit to four layers of controls and audits for how their most advanced AI models are built and deployed. The first layer calls for strong internal controls to monitor what AI systems can do during training and deployment, covering threats in cybersecurity, biosecurity, and chemical security, and making sure models do not access outside systems in unintended ways. The second layer requires a dedicated internal team to check that those controls and detection tools are working properly and to fix problems that surface. The third layer brings in independent outside auditors or evaluators to review the controls. The fourth layer assigns an independent board committee to oversee the safety teams and auditors and to make sure identified problems are addressed. The companies also agreed to meet regularly to develop shared safety standards and best practices as AI systems grow more capable. The text of the accord notes that it may eventually make sense to write some of these steps into laws or regulations, but the commitments themselves remain voluntary. Hours later, Trump signed a separate executive order titled "Inaugurating the Era of Super Intelligence," directing every federal agency to replace the terms "artificial intelligence" and "AI" with "super intelligence" and "SI" in official correspondence, public communications, websites, and reports, to the maximum extent permitted by law. The order argues that the word "artificial" undersells the technology's capabilities and that "super intelligence" better captures its promise and rapid advance. It gives the president's science and technology adviser 60 days to propose legislative language that would formally define the new term. Speaking to reporters after the meeting, Trump made clear the administration intends to keep the United States ahead in the global race for AI leadership, and he rejected calls for Washington to cooperate with China on AI safety. "Whoever wins superintelligence wins. You're gonna have a winner and a loser, and you're probably not gonna have a second place," he said. "We're leading now over China and everyone else, and I want to keep it that way." He argued that a joint effort with Beijing could hand over American secrets, and said industry self-policing would be enough. The White House event also saw the launch of America.gov, a new AI-powered government portal pitched as a single point of access for federal services, where the renaming was announced. The announcements arrive at a moment of growing concern about frontier AI systems. In recent weeks, there have been calls for the United States and China to work together on safeguards against misuse of advanced AI, including fears that the technology could be turned toward cyberattacks or biological weapons, following a string of high-profile incidents involving American companies. Trump's stance — voluntary commitments at home, no partnership with Beijing — sets the tone for how his administration plans to handle those pressures in the months ahead.
