Dwarkesh Patel on why Sonnet 5 and Opus 5 trail GLM 5.3

Dwarkesh Patel said a discussion with John, Beren, and Charlie questioned why Sonnet 5 and Opus 5 feel weaker than GLM 5.3, even though Anthropic could use raw logit distillation from Fable and train on Fable's environments. The discussion raised questions about the value of distillation, what makes it effective, and which model behaviors are hard to extract through it.
