Open Weights and American AI Leadership

As Washington weighs banning Chinese open-weight models over the Kimi K3 accusation, Jensen Huang publishes 'Open Weights and American AI Leadership' — his first-ever post on X — initially signed by 25 companies including Nvidia, Microsoft, Meta, IBM, Hugging Face, Mozilla, and the Linux Foundation. The letter defends distillation as 'a widely used technique for model improvement,' argues open models strengthen rather than weaken security, and urges targeted enforcement over category-wide bans. Within days it gathers over 270 signatories; OpenAI, Google, and Amazon sign after first abstaining. Anthropic — the alleged victim of the distillation — stays out. On July 27, Dario Amodei publishes the company's own position instead: Anthropic 'has never advocated for a ban on open-weights models' and calls safe open models 'a public good,' but asks for three things the letter does not — tighter chip export controls, a crackdown on industrial-scale distillation, and mandatory safety testing for any sufficiently capable model. The episode maps the industry's fault line: who profits from open weights, who is exposed by them, and whether openness is a strategic asset or an attack surface.
