Thought Leadership
In an open letter, over 20 tech companies call for open-weight AI models without premature state restrictions.
More than 20 US technology companies, including Nvidia, Microsoft, Meta, and Palantir, have appealed to policymakers in an open letter not to impose premature restrictions on open-weight AI models. The signatories warn that broad limits could stifle competition and drive innovation overseas. Furthermore, the companies argue that closed models do not guarantee higher safety. The letter states:
“Relying solely on closed models is not inherently safe: they can be breached, misused, or fail in ways that outsiders cannot detect. And concentrating advanced AI capabilities behind a small number of closed models compounds that risk.”
Open letter from more than 20 US technology companies
Elon Musk expressed his support for the letter via the platform X, although his company SpaceX did not officially sign the document.
Call for Targeted Safeguards Instead of Bans for Open-Weight AI
The signatories advocate addressing concerns regarding unlawful reuse of models through targeted legal and commercial frameworks rather than sweeping restrictions. The importance of an open approach is stated as follows in the letter: “Our AI leadership will be judged not by one frontier AI model, but by whether the United States builds a strong, open ecosystem that diffuses into every sector. This is essential for creating opportunities for innovation and prosperity across the country.”
Previously, nearly 200 Silicon Valley companies, including Proton and Y Combinator, had expressed opposition to restrictions on accessing international open-weight models in a separate appeal.
Reactions From OpenAI and Economic Context
Executives at OpenAI also commented on the topic. Greg Brockman, President of OpenAI, emphasized the importance of democratizing AI and providing broad access to various models during a briefing in New York. Sam Altman, CEO of OpenAI, likewise publicly welcomed the initiative.
Industry analysts also point to the economic interests of the participating infrastructure providers. Companies such as Nvidia and Microsoft benefit from the widespread use of interchangeable open-weight models, as these increase the demand for graphics processors, cloud capacity, and software applications.
