This paper introduces Retrospective Self-Distillation (RSD), a framework enabling AI agents to self-improve by converting unverified experience into dense supervision without relying on ground-truth solutions or external rewards. By allowing the model to act as both student and teacher using retrospective context, the approach achieves significant performance gains in complex environments like ScienceWorld and ALFWorld. The method demonstrates that naturally accumulated data can drive persistent capability growth through iterative co-evolution of the model, its dataset, and its supervision signals.
Self-Evolving Agents through Privileged Retrospective Distillation
arXiv:2610.27495v1 Announce Type: new Abstract: Self-evolving agents aim to improve from their own experience rather than remain fixed after deployment, but naturally collected trajectories often lack ground-truth solutions or verifier-derived rewards. We introduce Retrospective Self-Distillation (RSD), a multi-round framework that turns such experience into dense supervision using privileged retrospective context. For each on-policy trajectory, the same underlying model acts as both student and teacher: the teacher re-scores the student's realized actions while conditioning on cross-task precedents and lessons, together with turn-level reflection and future hindsight from the completed trajectory. The resulting teacher distribution is distilled back into the policy through on-policy self-distillation. Across rounds, the experience bank grows and the retrospective context is refreshed, allowing the model, its data, and its supervision to co-evolve. We further introduce frontier-guided context-policy evolution, where a stronger frontier model proposes constrained edits to how privileged context is constructed. Across ALFWorld, ScienceWorld, and SearchQA with Qwen3-8B and Qwen3-14B, RSD improves performance by up to 59.7% relative to the base model, while frontier-guided context-policy evolution adds up to a further 44.7% relative improvement over a fixed context policy. These results show that naturally accumulated experience can be converted into persistent model capability without ground-truth trajectories or verifier-derived rewards for the core policy update.
