Nvidia and Palantir urge US not to ban ‘open’ AI models after China scare

The Trump administration this week staked out a new position that could reshape its approach to AI policy, accusing Chinese companies of stealing U.S. technology even as it defends open AI development.

Earlier this year Anthropic sent letters to U.S. lawmakers warning about the practice, formally accusing Chinese firms Moonshot, DeepSeek and MiniMax of industrial-scale distillation of its Claude models.

Nvidia , Microsoft , Meta , Palantir and more than 20 other companies released a letter Friday urging policymakers to avoid "premature restrictions" on open-weight artificial intelligence models that would "stifle competition or drive innovation overseas."

The letter comes amid growing debate in Washington over whether access to Chinese-developed open-weight AI models should be limited because of national security and intellectual property concerns.
