Tech Giants Rally for Open-Weight AI Ahead of U.S. Policy Debates

Nvidia, Microsoft, Meta, OpenAI (later joined), Mistral, Palantir and other tech players signed an open letter urging U.S. policymakers not to curb open-weight AI models, arguing they enhance safety, spur innovation, and support national sovereignty. The letter cites Moonshot AI’s Kimi K3 as a leading open-weight model, defends distillation techniques, and calls for targeted, not sweeping, regulatory action. In total, 32 signatories had joined by press time, with Elon Musk publicly supporting the stance even though SpaceX wasn’t listed as a signatory.
