Tech Giants Unite Behind Jensen Huang's Open Weights Letter

NVIDIA CEO Jensen Huang initiated an open letter titled "Open Weights and American AI Leadership," quickly garnering signatures and public support from industry giants and institutions including Google, Microsoft, AMD, OpenAI, Cohere, and Sakana AI. The current conclusion is that mainstream industry forces have formed a consensus, sending a clear signal to Washington policymakers: the development of open-weight models should be supported.

Confirmed

Core viewpoints articulated by Jensen Huang in the open letter include: AI, as a new representation of knowledge, will transform every industry, drive every company, and involve construction by every nation; open models help enhance safety and cybersecurity, accelerate the diffusion of innovation, and support technological sovereignty; the AI ecosystem requires both closed and open-source models to coexist.

Multiple companies have publicly stated their positions or signed the joint letter: Google CEO Sundar Pichai emphasized that Google has always benefited from open source, and beyond Gemini, DeepMind also provides open-weight models like Gemma. AMD confirmed it signed the letter alongside Microsoft and others, stressing that a robust AI ecosystem requires open standards, interoperability, and choice at the software, system, and hardware levels. OpenAI has signed, and Elon Musk has expressed similar support. Cohere signed the initiative, emphasizing that AI should be controlled by those who use it, rather than becoming a tool of control for a few tech giants. LM Studio joined the co-signature, stating that running AI autonomously is its ultimate mission, and open-weight models are key to this path. Applied Compute also confirmed its co-signature. Sakana AI signed the open letter, expressing a desire to give back to the community from which it has long learned. Former OpenAI executive Mira Murati publicly voiced her support, arguing that AI itself must be distributed because the knowledge to make it truly useful is dispersed among scientists, engineers, and others.

Unconfirmed

Regarding OpenAI's participation, @bindureddy raised doubts. He pointed out that OpenAI has been lobbying to restrict open-source AI for years, and it remains uncertain whether this signature represents a genuine shift or merely PR for a potential IPO. The author believes OpenAI's sincerity can only be verified when it actually releases and opens the weights of models like GPT-6.

Why it matters

This joint signature represents a rare collective statement in the AI industry's debate over the "open vs. closed" route. Hardware vendors like NVIDIA and AMD, teaming up with software and model giants like Google, Microsoft, and OpenAI, have crossed specific commercial competitive boundaries. This is not just about choosing a technological path; it directly impacts the future direction of AI regulatory policy, demonstrating the industry's determination to defend the open-weight model ecosystem.
