Nvidia, Microsoft, Meta, and over 20 other technology companies issued a joint letter on July 24 urging U.S. policymakers to avoid broad restrictions on open-weight AI models. These companies argue that maintaining an open ecosystem is essential for national competitiveness, innovation, and cybersecurity. The signatories, including IBM, Palantir, Hugging Face, Mozilla, Mistral, Andreessen Horowitz, and Y Combinator, contend that American AI leadership depends on the wide diffusion of these technologies across every economic sector.

The public appeal arrives as the Trump administration evaluates its policy stance following concerns regarding Moonshot AI, a Chinese developer whose Kimi K3 model was accused by White House official Michael Kratsios of using distillation (a process where a smaller model is trained on outputs from a more sophisticated one) to appropriate technology from Anthropic’s Fable 5 model. Treasury Secretary Scott Bessent indicated that the U.S. government might sanction entities found to have improperly utilized such techniques to misappropriate intellectual property.

While the coalition defended open-weight systems—which allow developers to download and customize underlying parameters—they acknowledged that unlawful extraction of value from proprietary models requires attention. The group advocated for targeted legal and commercial frameworks to address these specific abuses rather than sweeping regulations that could stifle innovation. Notably, major proprietary AI developers including OpenAI, Anthropic, Google, and Elon Musk’s xAI did not sign the letter. Nvidia CEO Jensen Huang, who supported the initiative via his first post on X, emphasized that open models are critical for enabling national sovereignty and accelerating development in all industries.
