Nvidia CEO Jensen Huang, alongside executives from Microsoft, Meta Platforms, and IBM, has signed an open letter to lawmakers advocating for the support of open-source artificial intelligence models.

The coalition, which includes dozens of technology firms and industry groups, published the statement on X on Friday, marking a coordinated effort by the sector's largest players to influence the ongoing policy debate surrounding AI development and regulation.

The intervention highlights the growing tension between proprietary and open-source approaches to AI, a divide that has significant implications for market structure and competitive dynamics.

By publicly endorsing open models, these companies are signaling that they view accessibility and interoperability as critical to the next phase of technological advancement.

This stance contrasts with the more guarded positions often taken by firms that rely heavily on closed ecosystems for their competitive advantage.

The letter comes at a time when regulators are increasingly scrutinizing the AI sector, with questions around safety, intellectual property, and market concentration dominating the discourse.
