OPID: On-Policy Skill Distillation for Agentic Reinforcement Learning

arXiv:2606.26790v1 Announce Type: new Abstract: Outcome-based reinforcement learning provides a stable optimization backbone for language agents, but its sparse trajectory-level rewards provide little guidance on which intermediate decisions should be reinforced or suppressed. On-policy self-distillation offers dense token-level supervision, yet existing skill-conditioned variants often rely on external skill memories or retrieved privileged context, which are costly to maintain and can be mismatched with the state distribution induced by the current policy in multi-turn interaction. We propos

Why this matters
Why now

This paper addresses a core challenge in developing robust language agents by proposing a novel distillation method to improve decision-making guidance, which is crucial for the ongoing advancement of AI agentic systems.

Why it’s important

Improving the efficiency and effectiveness of training autonomous AI agents will accelerate their development and deployment, impacting white-collar workflows and the broader software landscape.

What changes

The proposed 'On-Policy Skill Distillation' (OPID) offers a more stable and less costly method for agents to learn from sparse rewards, potentially leading to more sophisticated and reliable AI agents.
