Merged summary
TL;DR - On-Policy Reverse Distillation (OPRD) helps stronger models learn from weaker teachers without inheriting their performance ceiling. It accelerates verifier-guided optimization by amplifying teacher-aligned, verifier-supported updates while preserving the underlying policy objective’s stationary points.
- OPRD measures the teacher’s policy shift relative to its reference policy on student-generated rollouts.
- It rescales only verifier-supported student updates aligned with that shift, allowing the student to improve beyond the teacher.
- In successive transfer and multi-teacher distillation, OPRD reportedly achieves higher performance with fewer updates than existing reinforcement-learning and distillation methods.
- OPRD students remain stylistically closer to verifier-RL models than to their teachers, suggesting that teacher guidance accelerates rather than redirects learning.
