25 U.S. Tech Firms Defend Open AI Models Amid China Tensions

Major tech coalition opposes AI restrictions

Twenty-five leading American technology companies, including Microsoft, Meta, and Nvidia, signed an open letter Friday urging the U.S. government not to impose restrictions on certain forms of artificial intelligence, according to The Washington Post.

While the letter made no mention of China, the position directly benefits Chinese AI companies that some U.S. policymakers and industry voices argue should face stricter oversight. The signatories took their stand as the Trump administration considers penalties against Chinese firms for their AI development practices.

The open model debate

The letter specifically defended "open weights" AI models—systems that are freely available for anyone to download and use. Leading Chinese companies including DeepSeek and Alibaba distribute their best AI models under this open approach, creating free alternatives to paid American services from OpenAI and Google.

As Chinese open models have approached the performance of premium American offerings, national security officials and some tech executives have raised concerns about security risks and potential misuse of U.S. technology.

Treasury Secretary Scott Bessent said Tuesday that Chinese companies using "distillation"—a technique where AI systems learn from other models—could face sanctions. The tech coalition's letter explicitly defended distillation as a legitimate development method. "Policy makers should be careful not to conflate legitimate model-development techniques with misappropriation," the letter stated.

Why it matters

The letter reveals a significant split in Silicon Valley over how to compete with China in AI. Many of the signatories benefit commercially from using or offering low-cost open models, including those from Chinese sources. Their position puts them at odds with voices calling for a more protectionist approach to maintain American AI leadership. The debate will shape whether the U.S. pursues open innovation or restricted access as its core AI strategy.

Notable absences and support

Google, OpenAI, Anthropic (maker of Claude), and Elon Musk's SpaceX (which offers the Grok chatbot) did not sign the letter. However, both Musk and OpenAI CEO Sam Altman publicly welcomed the letter in posts on X. Google and Anthropic did not respond to requests for comment.

The diverse coalition of signatories and the public support from non-signers suggests broad industry concern about potential restrictions, even as companies compete intensely in the AI market.
