Open letter aims to protect open-weight AI in the US
50 technology companies, including NVIDIA and Microsoft, are urging US politicians not to restrict open-source AI. They argue that "open-weight" AI is crucial for innovation and security.
What happened?
A coalition of 50 prominent technology companies has signed an open letter to the US Congress. The letter urges the US not to introduce restrictions against AI models that share their "weights" — the parameters that define the model's function. Signatories include tech giants such as NVIDIA and Microsoft, as well as AI specialists like Mistral and Hugging Face.

”An open letter signed by 50 companies, from NVIDIA and Microsoft to Mistral and Hugging Face, urges Washington not to restrict open weight AI.”
Why it matters
The initiative is motivated by the belief that free access to AI models, similar to open-source software, fosters innovation and robust security. The companies argue that transparent AI systems facilitate auditing, improvement, and faster identification of vulnerabilities, which ultimately leads to safer and more reliable AI. A central point is that open-weight AI enables sovereignty for states and organisations as they can inspect and control the code themselves, unlike closed systems where this is not possible.
Who is affected?
This primarily affects AI developers, researchers, and companies that rely on or contribute to the open-source AI ecosystem, as well as the US legislators targeted by the letter. End users may also be indirectly affected through access to more innovative and potentially safer AI products. The decision could also shape the US position in global AI competition.
What else you should know
The letter is seen as an attempt to influence the US approach to AI regulation, which has so far been unclear regarding "open-weight" AI. The debate surrounding openness versus control in AI development is currently one of the most prominent in the technology industry.
