Jensen Huang, Meta, and Others Sign Open Letter Supporting Open-Source AI, Opposing Washington Restrictions

On July 24, Nvidia CEO Jensen Huang posted his first tweet on X, publicly endorsing open-source AI. He joined more than 20 companies in signing an open letter entitled "Open-Weight and American Leadership in AI," including Meta, a16z, Y Combinator, Hugging Face, Mistral AI, and Perplexity. The action comes as Washington debates policies to restrict open-source AI and as Chinese companies such as DeepSeek and Kimi K3 demonstrate that open-source models can achieve efficiency comparable to top closed-source models. Closed-source frontier labs including OpenAI, Anthropic, and Google did not join the letter. Huang's tweet and the coalition signal a shift in the AI industry from technology-driven competition to competition over rules and ecosystems. Nvidia is trying to build a moat of alliances to maintain its position as a compute supplier.
