Wow. NVIDIA just dropped the clearest, strongest letter yet on open-weight models — co-signed by Microsoft, Palantir, ServiceNow, Box, me and a growing list of real builders. Read it. Internalize it. Share it. Open weights are not a risk to American leadership. 
They are American leadership. They expand access so startups, universities, hospitals, factories and main-street businesses can actually use frontier capabilities instead of renting them from three closed labs. 
They create real competition.
They give companies sovereignty over their own models and data.
 They strengthen security through transparency instead of hoping a handful of black-box providers never get breached or decide to gatekeep. The letter says it perfectly: 
“Policymakers have an important opportunity to act… keeping the frontier plural by avoiding premature restrictions on open models that stifle competition or drive innovation overseas.” Exactly. Which is why we have to push back hard and now on Dario Amodei and Sam Altman. Both have spent the last two years lobbying Washington for exactly the kind of restrictions this letter warns against — framing open weights as an existential danger while their own closed models sit behind high walls and high prices.
 Their solution always somehow ends with fewer competitors, higher barriers, and more control concentrated in the same few labs that already dominate. That is not safety. 
That is moat protection dressed up as safety. NVIDIA and its partners just put the opposite case on the table in public: openness is how America wins. Diffusion is how America wins. A plural frontier is how America wins. If we let the closed-lab lobby write the rules, the only “open” models left will be the ones coming from overseas. The letter is out. 
The case is clear. 
Push back now. Open weights. American leadership. No premature restrictions. NONE!
