Whoa, Jensen Huang's debut on X: fully backing open-source weight models, emphasizing that this is the core of technological sovereignty and industry implementation. NVIDIA founder and CEO Jensen Huang posted his first-ever tweet on X: He publicly shared a policy open letter spearheaded by NVIDIA and co-signed by tech giants, investment firms, and open-source communities like Meta, Microsoft, IBM, Dell, a16z, Palantir, Hugging Face, and Y Combinator. The letter is titled *Open Weights and American AI Leadership*. The open letter directly addresses the ongoing debates among U.S. legislators and policymakers regarding the security risks and strict regulations surrounding open-source large models. The letter argues that America's AI leadership shouldn't be defined by a single cutting-edge closed-source model but should rely on an innovative ecosystem that balances openness and resilience. Open-source weight models allow developers, businesses, and research institutions to deploy and fine-tune proprietary models as needed—without paying exorbitant closed-source API fees or training from scratch. This approach safeguards data privacy and technological sovereignty while preventing market monopolization by a few closed-source model providers. As the core supplier of global AI computing infrastructure, NVIDIA's support for open-source weights is commercially logical. Closed-source model developers tend to control traffic and compute premiums through vertically integrated closed loops. In contrast, the widespread adoption of open-source weights can drive the commoditization of foundational models, redirecting industry value to underlying hardware compute power and vertical application implementation. Jensen Huang concluded in his post that the global market needs both cutting-edge closed-source models and cutting-edge open-source models.
