Nvidia, Microsoft and other technology companies have jointly called on US policymakers to support open-weight AI models and avoid regulatory measures they say could limit access and innovation. Multiple outlets report that more than 20, and up to 25, companies and organizations sign an open letter titled “Open Weights and American AI Leadership.” The signatories include direct rivals and a mix of firms and organizations such as Meta, IBM, Dell Technologies, CrowdStrike, Palantir, ServiceNow, Hugging Face, Perplexity, Mistral, and venture and other groups.
The letter argues that open-weight approaches help drive competition and technological progress, and that restricting such models could push development overseas. Some coverage also frames the push as a response to recent controversy involving AI systems and open-source infrastructure, including a report that a Chinese AI helped Hugging Face stay operational after a hack tied to OpenAI-related systems.
Overall, the sources present the same core position: the coalition urges Washington not to impose “premature” or “sweeping” restrictions on open-weight models or related processes such as distillation, and instead to promote development to maintain US AI leadership.
