A growing fight over Chinese artificial intelligence is spilling into Silicon Valley, with nearly 200 startups warning the Trump administration that restricting access to Chinese open-weight AI models could hurt the very companies driving the next wave of American innovation.
In a coordinated appeal sent Wednesday, the newly formed Little Tech Association urged President Donald Trump and senior administration officials to reject a blanket ban on Chinese open-weight AI models. The group argues that limiting access would raise costs for startups, reduce competition, and strengthen the market position of a small number of dominant U.S. AI companies.
Y Combinator, Proton and 200 startups urge Trump not to block Chinese AI models
The letter, shared by Politico, marks one of the first organized efforts by the broader startup community to weigh in on one of Washington’s most closely watched AI policy debates. Members include nearly 200 venture-backed startups, with support from organizations such as Proton and Y Combinator.
At the center of the dispute are open-weight AI models developed by Chinese companies including Moonshot AI and Alibaba. Unlike closed commercial systems, open-weight models make their trained model weights publicly available, allowing developers to download, fine-tune, and run them on their own infrastructure. Many startups rely on these models as a lower-cost alternative to commercial offerings from OpenAI and Anthropic.
“American leadership requires two things: world-leading American open-weight models and continued access for U.S. builders to open models already available worldwide,” the founders wrote in the letter, which was addressed to Trump, Commerce Secretary Howard Lutnick, Office of Science and Technology Policy Director Michael Kratsios, and other administration officials. The group called for targeted safeguards instead of sweeping restrictions.
Startups fear a ban would favor AI giants
The debate gained momentum after reports suggested the Trump administration was weighing new restrictions on Chinese AI models following the release of Moonshot AI’s Kimi K3 model, which drew attention across the AI community for its performance.
That possibility alarmed many startup founders who depend on affordable open-weight models to build products without spending heavily on API credits from larger AI providers.
“There’ll be hundreds of companies that instantly die,” Suhail Doshi, founder of AI infrastructure startup Particle and a member of the Little Tech Association, told POLITICO. “It’s great for Anthropic. We’re all going to have to spend money on Anthropic.”
According to people familiar with internal discussions, senior White House and Cabinet officials discussed the issue earlier this week. A blanket prohibition on Chinese open-weight models was reportedly not seriously considered during those conversations.
The White House has not announced any policy changes.
“The United States leads the world in AI innovation, and President Trump will keep it that way. The Trump Administration is doubling down on innovation to widen the gap between America and the rest of the world,” White House spokesperson Liz Huston said in a statement.
A White House official added that any future policy would come directly from the administration, calling reports of pending action “baseless speculation.”
Washington sharpens its focus on Chinese AI
The administration has increased scrutiny of Chinese AI developers in recent days.
Treasury Secretary Scott Bessent said Tuesday that the administration would investigate whether Chinese AI companies improperly distilled American models, raising the possibility of sanctions for companies found to have engaged in intellectual property theft.
Kratsios made similar allegations Wednesday, claiming Moonshot AI used Anthropic’s Fable model during the development of Kimi K3 through what he described as a sophisticated internal distillation platform built to avoid detection. He said the administration had information suggesting Moonshot acquired Nvidia GB300-equipped servers despite export restrictions.
Moonshot AI has not publicly responded to those claims.
Kratsios stressed that the administration supports open-weight AI development and competitive AI ecosystems, drawing a distinction between legitimate model distillation and large-scale intellectual property theft.
Trump faces startup backlash over potential ban on Chinese open-weight AI models
The debate reflects a widening split inside the AI industry over how Washington should respond to China’s growing AI capabilities.
Large AI companies, including Anthropic, have pushed for tighter restrictions on Chinese AI developers, citing national security concerns and the protection of American intellectual property.
Startups see the issue differently. Many argue that restricting models already available worldwide would do little to slow China’s AI progress and would instead place American startups at a disadvantage by limiting access to affordable technology.
Harry Godfrey, executive director of the Little Tech Association, said policymakers should avoid broad prohibitions that could unintentionally raise costs for small companies.
“The answer here would be: What is the lightest-touch way that doesn’t raise costs, limit access or inhibit American innovation while still addressing legitimate security concerns,” he said.
The Commerce Department, which oversees export controls through its Entity List, had not drafted plans to add Chinese AI companies as of Wednesday, according to a person familiar with the matter.
For startup founders, the outcome could shape more than AI policy. It may determine who can afford to build the next generation of AI companies, and whether the industry’s future remains open to newcomers or becomes concentrated in the hands of a few well-funded players.
