Matthew Berman's 55-Minute 'I'm Disappointed' Breaks Down the Open-Weights Split: Huang's 50-Signatory Letter vs Anthropic's Absence
Berman's July 29 video (63,282 views, 3,297 seconds) walks through the industry fracture over open weights, anchored on NVIDIA's letter — Jensen Huang's first-ever X post on July 24, which doubled to 50 signatories including OpenAI, Google, Meta, Microsoft, and Palantir while Anthropic and Amazon stayed off it — against Anthropic's July 27 position post. Anthropic's three asks are specific: no powerful chips or chipmaking equipment to China plus a smuggling crackdown, policy action against 'industrial-scale distillation operations,' and mandatory pre-release safety testing for cyber, bio, and alignment risk on all sufficiently capable models, open and closed. The post opens by insisting 'Anthropic has never advocated for a ban on open-weights models' and that risk 'should be empirically answered by rigorous pre-release testing, not assumed in advance.' Chapters cover Kimi K3, Jevons paradox, distillation, and whether to ban Chinese models — the practical stake for builders is whether the open weights they depend on stay legal to ship.
