As US weighs response to Chinese AI, industry urges against broad open-weight restrictions

Several AI companies, including Hugging Face, Meta, Microsoft, Mistral, and Nvidia, have signed an open letter urging policymakers against broad “premature restrictions” on open-weight AI models. This comes as the U.S. debates its response to allegations of Chinese AI labs stealing intellectual property. Replit CEO Amjad Masad stated that banning Chinese open models is akin to banning open models generally, highlighting the interconnected ecosystem, as seen with Thinking Machines Lab's Inkling model trained with Moonshot’s Kimi 2.5.
