Who's afraid of Chinese models?

https://i0.wp.com/dithering.passport.online/assets/2026-07-DitheringCoverart.jpg?w=128&h=128&ssl=1
The author argues that the reaction to Chinese open weight models is overblown, as they are not necessarily cheaper to serve on a marginal cost basis, but rather are benefiting from a lack of compute and a price umbrella. The author suggests that the US should pass a law to make distillation of models fair use and to loosen restrictions on using frontier labs' models for cybersecurity, to ...
