An article summarized by CNBC:
More than 20 major technology companies, including Nvidia, Microsoft, Meta, and Palantir, signed a letter urging U.S. policymakers not to impose broad restrictions on open-weight AI models. The companies argued that allowing developers to download, modify, and run these models promotes competition, innovation, and wider access to AI, warning that overly restrictive regulations could push AI development overseas and concentrate power among a small number of companies.
The letter comes as concerns grow over the rapid advancement of Chinese AI models, particularly Moonshot AI's recently released Kimi K3, which has outperformed some leading U.S. models on industry benchmarks. U.S. officials have raised questions about whether Chinese firms have improperly used American intellectual property, but the companies signing the letter argued that concerns over AI model theft should be addressed through targeted legal action rather than sweeping limits on open AI technologies.
Notably, OpenAI and Anthropic did not sign the letter, although OpenAI President Greg Brockman said he supports broad access to AI and has not participated in discussions about banning Chinese open-weight models. The signatories concluded that America's long-term AI leadership will depend not only on building powerful frontier models but also on fostering an open AI ecosystem that encourages innovation across the economy.
