Zhejiang University

Research official + media 2 src. ~1 min

A new on-policy distillation method where a teacher and student model relay segments of a reasoning trajectory to each other, aiming to keep the student's training distribution closer to what it will see at inference than standard full-trajectory distillation.

Why it matters

Landed on HuggingFace Daily Papers (July 29, 2026, 27 upvotes); on-policy distillation is an active area for cheaply transferring reasoning ability from large to small models.

Importance: 2/5

Incremental research contribution in an active area, modest HF Daily Papers traction (27 upvotes).
