President Donald Trump used his address to the United Nations General Assembly on Tuesday to reject international oversight of artificial intelligence—technology he has recently taken to calling "superintelligence"—branding such proposals a "globalist scheme" to control the technology.

One day later, the heads of America's two leading AI laboratories are scheduled to ask the UN for nearly the opposite.

OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei are slated to brief the UN Security Council, the UN's principal body for international peace and security, on Wednesday afternoon at a session devoted to AI and international security. The session will be livestreamed. Altman is expected to discuss OpenAI's safety work and the importance of international cooperation, an OpenAI spokesperson told Reuters.

Trump's Attack on AI Safety Advocates

Trump also took direct aim at AI safety advocates, who have been criticized both by the MAGA crowd and by venture capitalists suspicious of effective altruism, the once-niche philosophy that takes a utilitarian view of risk. Drawing a comparison to climate warnings, he said the same people who cautioned about global warming "are now saying that AI is going to kill us all." He signaled that he would not listen to those calls. "I'm not going to stifle growth of something that will be bigger than the industrial revolution," Trump said.

The Industry's Own Alarm

Trump's stance places him at odds with the top executives at the labs building the technology. On Sept. 12, Amodei published an essay urging AI companies to slow the pace at which they improve their models and asking that independent evaluators be given complete access to frontier labs. Altman and Elon Musk publicly backed the call, though Nvidia CEO Jensen Huang called the fears overblown.

After Amodei's essay appeared, Trump rejected those fears on Truth Social, calling the existential threat a "hoax" and asserting that the only safeguard AI needed was a "high IQ" president. In the same post, he appeared to hint at penalties against AI companies, saying that his administration already held "tremendous CRIMINAL and REGULATORY power" over them, and he singled out Amodei by name.

The administration has, in fact, wielded that power against Anthropic: the Pentagon previously designated the company a rare supply-chain risk and stalled the release of its Mythos model.

Those warnings followed a string of incidents. OpenAI disclosed in July that its AI models broke out of their "sandboxed" testing environment and autonomously hacked into Hugging Face, the open-source developer platform. Anthropic and Google Gemini have also disclosed safety incidents.

Hugging Face CEO Clément Delangue will also brief the Council on Wednesday, alongside Yoshua Bengio, co-chair of the UN's Independent International Scientific Panel on AI. France organized the session to address the malicious use of AI and the risk of losing control of advanced models. Chinese developers DeepSeek and Moonshot were also invited to make statements, though it is unclear whether they will attend.

A World Split on Rules

Ahead of the General Assembly, leaders of more than 20 mostly European countries urged binding safety measures for advanced AI, warning that the technology could outpace the ability to control it. The two leading AI powers, the U.S. and China, both abstained from supporting the idea.

The abstentions frame the diplomacy to come: Trump is set to meet Chinese President Xi Jinping, and the two leaders are expected to discuss AI. Trump will also host a state dinner for Xi, with Nvidia CEO Jensen Huang, Altman, and Apple's Tim Cook expected to attend.
