Jensen Huang's "Open Weights" letter, urging against AI model restrictions, swiftly doubled its signatories to 50 within a day, including tech giants like OpenAI and Google. This rapid expansion, spurred by Huang's X post, signals a new, accelerated tempo in technology policy. Notably, Amazon and Anthropic remained absent, a significant omission given their market influence and Anthropic's established safety position. While open weights offer businesses sovereignty to inspect and modify models, the letter falls short on critical issues like chip access, data residency, and the crucial auditability of AI agent actions. Companies must therefore proactively address these complex governance and liability challenges beyond mere model access.
