Nvidia and 24 other companies sign open-weights letter as Washington weighs Chinese AI model ban — OpenAI, Anthropic, and Google absent from the list

Nvidia and 24 other companies signed a letter urging Washington not to impose broad limits on downloadable AI models.

The group wants wider access to compute and shared research resources, and says model distillation should be handled with targeted law, not sweeping bans.

The letter comes as the U.S. weighs action against Chinese AI models, and OpenAI, Anthropic, and Google did not sign.

The move highlights a growing split over open-weights versus closed AI models and could shape future U.S. policy on competition and national security.
