Nvidia, Microsoft, Meta, Palantir and more than 20 other companies released a letter on Friday urging policymakers to avoid 'premature restrictions' on open-weight artificial intelligence models. The companies warned that such restrictions would 'stifle competition or drive innovation overseas.' The letter comes amid debate within the tech sector over Chinese open-weight AI models, which are gaining traction against offerings from American companies like OpenAI and Anthropic that primarily develop proprietary, closed models.
Tech Companies Warn Against Restricting Open-Weight AI Models
The group of U.S. tech companies stated in the letter that open-weight models strengthen competition and ensure that the benefits of the technology are 'broadly shared rather than concentrated in a few hands.' Open-weight AI models are available for users to download, modify and run on their own infrastructure.
The letter stated: 'Relying solely on closed models is not inherently safe: they can be breached, misused, or fail in ways that outsiders cannot detect. And concentrating advanced AI capabilities behind a small number of closed models compounds that risk.'
Nvidia CEO Jensen Huang and Microsoft CEO Satya Nadella both shared the letter on their personal social media accounts.
Moonshot AI's Kimi K3 Model Raises Concerns
Moonshot AI, a Chinese startup, released a model called Kimi K3 earlier this month that outperforms cutting-edge American offerings across some industry benchmarks. Officials and executives have been weighing whether or not to restrict access to Chinese models in the U.S.
White House advisor Michael Kratsios said Wednesday that Moonshot AI developed its Kimi K3 model by distilling Anthropic's technology. Distillation is a term for an AI training method where a smaller, less capable model is built using outputs from an existing, stronger model. Kratsios wrote in a post on X that 'large-scale, covert industrial distillation aimed at stealing proprietary U.S. technology' is 'unacceptable.'
Treasury Secretary and White House Respond to Chinese AI Development
U.S. Treasury Secretary Scott Bessent told CNBC on Tuesday that the Trump administration would look into whether Chinese companies were stealing American intellectual property. Bessent stated that the government has 'the ability to sanction them because of this theft.'
In the letter on Friday, the U.S. tech companies said that concerns about unlawful distillation should be addressed through 'targeted legal and commercial frameworks' instead of with 'sweeping restrictions on techniques that play an important role in AI innovation.'
The letter stated: 'Our AI leadership will be judged not by one frontier AI model, but by whether the United States builds a strong, open ecosystem that diffuses into every sector. This is essential for creating opportunities for innovation and prosperity across the country.'
OpenAI and Anthropic Did Not Sign Letter
OpenAI and Anthropic did not sign the letter. Both companies, which are each valued at nearly $1 trillion, are gearing up for potentially massive IPOs that could land as soon as this year. Anthropic confidentially filed its prospectus with the Securities and Exchange Commission in June, and OpenAI followed suit days later.
Greg Brockman, OpenAI's president, said Thursday that the company believes in broad access, and that he has not been involved in any conversations with the Trump administration about potentially banning Chinese open-weight models in the U.S.
Brockman told reporters during a briefing in New York City: 'I think that, that fundamentally, AI and AI usage is something that is actually very important to democratize. And so, for me, at a sort of deep level, I think that having more models, more usage, that is a good thing.'
