NVIDIA CEO Jensen Huang joins X with post backing open-weight AI

Q: Why does NVIDIA argue that restricting open-weight AI would concentrate gains in a few companies?

NVIDIA argues that restricting open-weight AI would stifle competition and push innovation overseas, which would concentrate the gains of AI development in the hands of a small number of companies. The letter also warns that relying exclusively on closed models creates a single point of failure, making the world more vulnerable if "everything just becomes one single model, one single point of attack, one single source of failure."

Q: How does the letter claim open models affect national AI sovereignty and cybersecurity?

The letter asserts that open models "strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty," arguing that they let countries build and inspect models themselves. It warns that restricting open models would stifle competition, push innovation overseas, concentrate AI power in few companies, and that relying solely on closed models creates a single point of failure that makes the world more vulnerable.

Q: How could restricting open-weight models push AI innovation overseas, per the article?

The letter argues that restricting open-weight models would stifle competition and concentrate the gains of AI in the hands of a small number of companies, which in turn would push innovation overseas. It also warns that relying only on closed models creates a single point of failure, increasing vulnerability and reducing the distributed innovation that open models enable.

Jensen Huang's first X post shared a letter from NVIDIA and 24 other companies urging US policymakers not to restrict open-weight AI.

TL;DR: NVIDIA CEO Jensen Huang joined X to share a letter from NVIDIA and 24 firms urging US policymakers not to restrict open-weight AI, arguing open models boost safety, innovation, and sovereignty while preventing concentration and single points of failure. He dismissed fears about Chinese open models and said they pose no displacement risk.

Jensen Huang has joined X, and his first post was not about GeForce GPUs, driver updates, or Blackwell. Instead, the NVIDIA CEO used his debut to share a letter signed by NVIDIA and 24 other companies urging US policymakers not to restrict open-weight AI models.

"AI will transform every industry, power every company, and be built by every country," Huang wrote. "Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models."

The letter, titled Open Weights and American AI Leadership, argues that restricting open models would stifle competition, push innovation overseas, and concentrate the gains of AI in the hands of a small number of companies. It also warns that relying exclusively on closed models creates a single point of failure. "If everything just becomes one single model, one single point of attack, one single source of failure, I think the world is much, much more vulnerable," Huang said separately to Axios.

OpenAI and Anthropic are notably absent from the list of signatories, with both companies warning about the security risks posed by Chinese open-weight models. Those concerns have also reached Washington, where Trump is reportedly considering new restrictions on Chinese AI models following the release of Moonshot AI's Kimi K3. The model recently ranked third on Artificial Analysis' Intelligence Index, behind only Anthropic's Claude Fable 5 and OpenAI's GPT-5.6 Sol.

NVIDIA does not particularly care which model runs on its chips as long as something does. Widespread open-weight model adoption means more people running inference workloads, which means more demand for the hardware and data center infrastructure NVIDIA sells. Conversely, US export restrictions on NVIDIA's most advanced chips have already reduced its China business significantly. Huang has opposed those controls for years.

Huang addressed the Chinese model question, saying, "open-source models that are excellent should be used." He dismissed the idea that running a downloaded Chinese model creates a security backdoor, pointing out that open weights can be inspected, modified, and run entirely offline. On whether China could displace American AI labs, he was blunt: "Zero possibility."
