Briefings
ReSAIL mitigates performance collapse in iterative agent self-distillation by prioritizing informative interaction steps and preserving privileged information (PI) conditioned behavior. On ALFWorld and TextCraft, ReSAIL sustained substantial gains across model scales over three cycles, achieving an average absolute gain of 22.5% in final-cycle success rates compared to self-distillation baselines. The method also improves action prediction accuracy for multimodal GUI agents on AITZ through sensitivity-guided selection of offline data.
Key points
- ReSAIL introduces Retentive and Selective Augmentation for Iterative Self-Distillation to mitigate performance collapse in iterative agent self-distillation.
- ReSAIL sustains substantial gains across model scales over three cycles, with an average absolute gain of 22.5% in final-cycle success rates on ALFWorld and TextCraft.
Context
Iterative self-distillation enables LLM agents to learn from successive deployments, offering a path toward recursive self-improvement. However, existing methods reveal a collapse in deployment performance across cycles. ReSAIL addresses this by prioritizing informative interaction steps and preserving PI-conditioned behavior as the student becomes the next teacher.
Limitations
Evidence is limited to ALFWorld, TextCraft, and AITZ platforms. Performance gains are reported as sustained over three cycles with average absolute gain of 22.5%, but specific failure modes or long-term stability beyond three cycles remain unverified.
