arXiv:2607. 04763v1 Announce Type: cross Abstract: We study on-policy distillation (OPD) for agentic tasks, where an LLM agent interacts with an environment over multiple turns and a student imitates a teacher over these multi-turn interaction histories.
arXiv:2609.14636v1 Announce Type: new Abstract: On-policy distillation (OPD) has become a standard approach for transferring capabilities from large teachers to compact students. Its cost, however, i...
The paper introduces DTDD, a Divergence-Triggered Dynamic Distillation framework that adapts on‑policy distillation by monitoring segment‑level student‑teacher divergence and initiating teacher takeover when divergence exceeds a threshold. During takeover, the student continues to receive standard OPD supervision on the prefix while the teacher generates a recovery suffix that the student learns via behavior cloning. Experiments across long‑horizon reasoning, base initialization, and multi‑turn agents show that DTDD reduces peak gradient norms, accelerates learning from a base initialization, and improves performance on ALFWorld tasks, with segment‑averaged triggers and behavior cloning proving most effective.
arXiv:2608. 16333v1 Announce Type: cross Abstract: On-policy distillation (OPD) aligns a student model with a teacher's logit distribution on student-generated trajectories.
On-policy distillation (OPD) aligns a student model with a teacher's logit distribution on student-generated trajectories. This approach has achieved strong empirical gains and can often surpass conve...
arXiv:2606. 15912v1 Announce Type: cross Abstract: Multi-turn agents that plan, invoke tools, and interact with environments offer a promising paradigm for solving complex tasks, yet their capabilities typically rely on very large models whose inference cost is prohibitive in practice.
