arXiv:2606.09348v1 Announce Type: new Abstract: Long-horizon agentic tasks pose a fundamental credit assignment challenge for outcome-base reinforcement learning: trajectory-level rewards verify final correctness but provide limited guidance on which intermediate reasoning steps or tool interactions contribute to the outcome. The difficulty is especially pronounced in multi-turn search agents, where successful trajectories may contain misleading actions and failed trajectories may contain valuable evidence-gathering steps. We propose PBSD (Privileged Bayesian Self-Distillation), a Bayes-calibr
The continuous advancements in AI agentic systems necessitate more robust and efficient methods for credit assignment, particularly as tasks become more complex and multi-step.
Improving how AI agents learn from long-horizon tasks directly addresses a core limitation in developing highly autonomous and reliable AI, impacting a wide range of applications.
This research introduces a novel self-distillation technique that could significantly enhance the learning efficiency and robustness of AI agents in complex, multi-turn scenarios.

More capable and reliable AI agents emerge, able to tackle longer and more complex tasks with fewer human interventions.
The widespread adoption of these improved agents could automate a greater portion of white-collar and knowledge-based workflows, increasing productivity.
Enhanced AI agent capabilities could accelerate scientific discovery and engineering innovation by autonomously conducting complex research cycles.
