Jensen Huang endorsed open-weight AI models, joining a coalition arguing that open ecosystems strengthen U.S. competitiveness. Nvidia shares slipped 0.9%.
Jensen Huang threw Nvidia’s weight behind open-weight artificial intelligence models on Tuesday, arguing the approach will sharpen American competitiveness and security.
In his first post on X, the chief executive shared a letter titled “Open Weights and American AI Leadership” signed by Nvidia and a coalition of technology companies. The document draws a direct line to the open-source software movement of the 1980s. The signatories said the United States should not gauge AI leadership by the success of a single frontier model. Instead, they argued, the measure should be the breadth of the ecosystem – the ability to spread AI across industries, institutions and countries.
“AI will transform every industry, power every company, and be built by every country,” Huang wrote in his post. He added that the world needs both closed frontier models and open ones.
The letter defined open-weight models as systems whose trained parameters can be downloaded, inspected, modified and run on an organisation’s own infrastructure. That setup, the signatories said, lets startups, universities and small businesses access advanced AI without training from scratch or paying a premium for each task. Open weights also cut reliance on a single provider, giving organisations control over their data and the ability to adapt models to specific needs.
The coalition conceded the risks. Released model weights can be altered and are hard to trace or reverse. Restrictions on open models, however, do not automatically improve safety, they argued. Wider access can help cybersecurity researchers find vulnerabilities and build safeguards. The letter also called for more computing resources and shared datasets, and warned policymakers that premature restrictions could push innovation overseas.
Several technology leaders publicly backed the position. Meta CEO Mark Zuckerberg said open source helps empower people and prevent centralisation. OpenAI CEO Sam Altman said he wants the United States to succeed in both open-source and proprietary AI. Microsoft CEO Satya Nadella described open-weight models as essential to a healthy AI ecosystem, saying they could strengthen American competitiveness while protecting national security.
