arXiv:2605.31490v1 Announce Type: new Abstract: On-policy distillation (OPD) provides dense teacher feedback along rollouts generated by the student and has emerged as a promising post-training paradigm for long-horizon reasoning. However, standard OPD typically generates full rollouts during training, which is computationally expensive and may expose the student to unreliable teacher feedback at late rollout positions, especially during early training. We identify the rollout horizon as a key bottleneck in OPD that substantially impacts training efficiency. Unlike Reinforcement Learning with
The continuous drive for more efficient and robust AI training methodologies, particularly for long-horizon reasoning in complex tasks, explains the focus on optimizing techniques like on-policy distillation.
Improving the efficiency of on-policy distillation directly reduces the computational burden and accelerates the development of advanced AI models, with implications for their deployment in real-world agentic systems.
The research suggests a potential pathway to significantly reduce the computational cost and improve the stability of training for certain AI models, which could accelerate progress in AI agent development.
