A coalition of 25 companies, including Nvidia, Microsoft and Meta, published an open letter on July 24 opposing restrictions on open-weight AI models. These companies argue that such a ban would weaken America’s strategic position in favor of China, whose open-source models like Moonshot AI’s Kimi K3 (2.8 trillion parameters) are advancing rapidly. OpenAI eventually joined the coalition under public pressure, while Anthropic refused to sign. The Trump administration has ruled out a blanket ban but is considering targeted sanctions against certain Chinese AI systems. This conflict is fundamentally driven by economics: closed-model labs depend on controlled access for revenue, while open-weight models allow anyone to download and deploy AI without licensing fees.
