The releases are the first ones since the companies warned about the dangers of not pacing AI development. The CEOs of both companies, Sam Altman and Dario Amodei, are also expected to address the United Nations Security Council this week as concerns as concerns about the potential dangers of AI mount. The Security Council is scheduled to meet on Wednesday to discuss AI and international security, bringing some of the industry's most influential executives and researchers into a forum traditionally focused on wars, nuclear proliferation and threats to global peace.

The two executives have argued that slowing certain advances does not mean stopping AI innovation, but rather allowing safeguards and alignment research to catch up with rapidly expanding capabilities. President Donald Trump has rejected the notion, saying on Tuesday that his administration won't seek to pace development. Speaking at the United Nations General Assembly, Trump said he's "not going to stifle growth of something that will be bigger than the industrial revolution." "Many say it will be bigger, or than the internet itself. We'll be very careful. We already have the DOJ and other law enforcement bodies that will rein things in if we have to. We'll only encourage super intelligence," Trump added, in reference to his decision to create an "AI Force" that will include the appointment of an "AI Czar." In a lengthy social media post this weekend, Trump framed concerns about AI development as partisan politics. "Over the years, there have been many Hoaxes, all generated by the Radical Left Dumocrats, for purposes of destroying our Country. RUSSIA, RUSSIA, RUSSIA, UKRAINE, UKRAINE, UKRAINE, Global Warming, Impeachment Hoax 1, Impeachment Hoax 2, Men in Women's Sports, Transgender for Everyone, and now, the decimation, or destruction, of AI," Trump wrote https://truthsocial.com/@realDonaldTrump/posts/117298821562014906 . "We will not in any way hinder or stifle the Growth of this incredible Industry. Rather, we will cherish it, help it, and watch over it, as it grows However, we will also be looking for BAD, and we can do that, very easily, with our already existing Criminal and Civil Justice System. For this purpose, I am forming the AI Force, much like I did Space Force, which has been a tremendous SUCCESS, in my First Term," he added. Trump has repeatedly rejected pacing the development of frontier models, saying the U.S. has to maintain its edge over other countries, particularly China. © Copyright IBTimes 2026.
