Microsoft, NVIDIA and 35 other companies and groups published a letter urging policymakers to avoid rushed regulation of open-weight AI models.

The letter argues that open models can boost competition and improve safety, and it proposes expanding compute access for startups and researchers.

Anthropic did not sign, while calls for tighter rules are also growing amid the rise of Chinese open models.

The effort is a policy push to protect U.S. AI competitiveness and research freedom, and it could shape future regulation.
