TurnOPD: Making On-Policy Distillation Turn-Aware for Efficient Long-Horizon Agent Training

Yuhang Zhou, Kai Zheng, Haoling Li +3

On-policy distillation (OPD) trains a student policy by matching a stronger teacher on the student's own trajectories, offering a promising framework for language agent training. H…
