iSDFT: open-source self-distillation method enables continual learning for LLMs

hbouammar · x · 2026-09-23

Researchers present iSDFT (Information-Proximal Self-Distillation) for effective continual learning in LLMs. The student generates on-policy responses while a demonstration-conditioned teacher provides token-level guidance; instead of matching the full teacher distribution, iSDFT builds the closest distribution satisfying a teacher-information constraint, with a KL anchor to the frozen initial model limiting drift. Backed by 500+ experiments, code, datasets, evaluators and checkpoints are all open-sourced.
