Silicon Valley Is Completely Divided Over Chinese AI

Chinese AI">

A huge debate is brewing in Silicon Valley over the proliferation of Chinese-made artificial intelligence tools, particularly “open-weight” AI systems that, by some measures, can compete with or even outperform some of the best US models. My WIRED colleague Hugo Lowell has written about the Trump administration’s internal debate on how to handle these Chinese models. Among AI companies in the Valley, the issue is proving even more divisive.

A top concern in both DC and the Valley relates to distillation, in which a less capable AI model is trained on the outputs of a more powerful one. In June, Anthropic accused the Chinese tech giant Alibaba of illicitly stealing its IP through distillation attacks. Then, earlier this week, the White House said that it believes the Beijing-based Moonshot AI had developed its Kimi K3 model by distilling Anthropic’s Fable 5 model.

Another big concern is how quickly China’s models are appearing and spreading. An open-weight AI model has its core components made public, so that it can be fine-tuned to suit a user’s needs. But they don’t have the kinds of guardrails on which Anthropic has been building its reputation. Yasir Atalan, deputy director and data fellow at the Center for International and Strategic Studies, points out that the main benefit of open-weight AI models is their speed of diffusion . They can spread especially easily “through Hugging Face, GitHub, cloud providers, local deployments, and third-party inference platforms,” he writes . If you’re Anthropic, and you’ve built a cult around safety and charge for access to your big expensive proprietary models, you have every reason to want to regulate this.

But some Silicon Valley startups—not the trillion-dollar ones like OpenAI and Anthropic—really don’t want the US government to put restrictions on these AI models. On Wednesday a group of over 200 startups called the Little Tech Association sent a letter to Michael Kratsios, science adviser to President Donald Trump, and US Commerce Secretary Howard Lutnick lobbying against an outright ban of open-weight AI models. The group, which includes famed startup incubator YCombinator, has argued in favor of certain safeguards but says that denying Americans access to AI models abroad would weaken US startups and create a monopoly among the AI giants.

Bill Gurley, the legendary tech investor and longtime partner at Benchmark Capital, has publicly argued in favor of letting “ the free market work .” In a lengthy blog that offers a nice little history of open-source software, Gurley writes that open-weight models avoid lock-in, encourage true academic research, and are critical for capital-constrained startups.
