US reportedly favors selective bans over blanket restrictions on Chinese open weight models

The Trump administration is reportedly considering targeted bans on specific Chinese open-weight AI models due to national security concerns, rather than a blanket restriction. In response, 25 tech firms including Microsoft, Meta, and OpenAI signed an open letter opposing such regulations. However, OpenAI and Anthropic are also privately lobbying for restrictions, facing price pressure from cheaper Chinese models.
