Twenty-five technology companies and industry groups have publicly urged Washington not to restrict open-weight AI, turning a policy debate into a visible split with major closed-model labs. The July 24 letter, titled “Open Weights and American AI Leadership,” was amplified by Nvidia CEO Jensen Huang in his first post on X, giving the campaign an unusually prominent public launch. Meta, Microsoft, Nvidia, IBM, Dell Technologies, Hugging Face, Mistral, Mozilla, the Linux Foundation and others signed, while OpenAI, Anthropic and Google were absent.
