Twenty-five technology companies, including Nvidia, Meta, and Microsoft, have signed an open letter defending open-source artificial intelligence models as critical to the United States' ability to compete globally. The letter, signed by the three industry giants along with 22 other firms, marks a coordinated show of support for open development of AI software at a time when the technology is under increasing regulatory scrutiny.
The signatories
Nvidia, known for its AI-focused chips, Meta, the parent company of Facebook and Instagram, and Microsoft, a leading cloud and AI platform provider, are the most recognizable names among the group. The other 22 companies were not identified in the public statement, but the coalition represents a broad cross-section of the technology sector—from hardware makers to software developers to social media platforms.
What the letter says
The open letter explicitly argues that open-source AI models are essential for maintaining US competitiveness. The companies contend that restricting or hindering the development and distribution of open-source AI would undermine innovation and weaken the country's position in the global AI race. The letter does not single out any specific legislation or regulatory proposal, but its release suggests the industry is pushing back against potential moves to tighten controls on AI development.
By defending open-source models, the group is making a case for transparency and collaborative progress in AI, as opposed to closed, proprietary systems. The letter emphasizes that open-source approaches allow for broader access, faster iteration, and more diverse contributions—factors the companies see as vital to staying ahead of competitors in China and elsewhere.
Reactions and next steps
The letter has been posted publicly, though it is unclear whether it was directed at a particular regulatory body or legislative effort. The companies did not announce any follow-up actions or a timeline for further advocacy. For now, the open letter stands as a collective statement from some of the most influential players in AI, signaling their united stance on the importance of open-source models for national competitiveness.
