U.S. Senator urges Trump to support open-weight AI models
Republican lawmaker argues for backing U.S.-developed AI models amid industry debate over open-source versus proprietary systems.

A Republican U.S. senator has called on former President Donald Trump to endorse open-weight artificial intelligence models developed in the United States.
The senator, who has not been publicly identified, framed the push as a strategic move to maintain American leadership in AI while addressing concerns over the dominance of proprietary systems. Open-weight models allow broader access to underlying code and data, fostering collaboration and innovation, the lawmaker argued.
The call comes amid an ongoing industry debate over the balance between open-source and closed AI systems. Advocates of open-weight models contend they promote transparency and accelerate technological advancement, while critics warn of potential security risks and intellectual property challenges.
The senator’s letter to Trump, which was not made public, underscores the political dimensions of AI policy as the U.S. seeks to compete with global rivals in the technology sector. The push aligns with broader efforts to ensure U.S. technological sovereignty in critical industries.
No further details on Trump’s response or potential policy implications were provided.
