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

Several major AI companies have signed an open letter urging policymakers against imposing broad restrictions on open-weight AI models, as the U.S. government considers how to respond to allegations that Chinese AI labs are stealing intellectual property and advancing their capabilities. The letter distinguishes between legitimate model-development techniques like distillation, which involves using one model's outputs to train another, and unlawful efforts to extract value from closed models. The signatories argue that open-weight models are important for AI innovation and cybersecurity defense, and that sweeping restrictions could stifle competition and drive innovation overseas. This reflects a divide in the AI industry, with closed-source AI companies notably absent from the letter having urged the administration to crack down on Chinese open-weight models that threaten their business models.
