OpenAI CEO Sam Altman will meet with senior Trump administration officials, lawmakers and economists in Washington, D.C., this week to preview the capabilities of the company’s upcoming family of artificial intelligence models. Altman has maintained a regular presence on Capitol Hill this year to alleviate policymakers’ concerns about the rapidly advancing technology. This visit lands during a debate over whether to restrict Chinese open-weight AI models. Altman is expected to field questions about cybersecurity and the company’s stance on open-weight models, according to a source. Chinese open-weight models from startups like Moonshot AI have rapidly caught up with leading American offerings, sparking anxiety about the U.S. lead. A coalition including Nvidia, Microsoft, Meta and Palantir released a letter on Friday urging policymakers to avoid “premature restrictions” on open-weight models. OpenAI signed the letter after it was initially published, but its allies have lobbied for restrictions. Nvidia CEO Jensen Huang is also meeting with lawmakers this week to discuss open models and “American leadership in AI.”
