Strong Teacher Not Needed? On Distillation in LLM Pretraining

This paper challenges the conventional assumption that knowledge distillation requires a stronger teacher to produce better students. Through systematic variation of architecture sizes and training token budgets, the authors find that even small, undertrained teachers can improve larger student models when language modeling and distillation losses are properly mixed. Counterintuitively, stronger teachers can saturate or reverse distillation gains, and distillation benefits generalization more than in-domain fitting.
