Open-MOPD: Diagnosing and Fixing Capability Imbalance in Multi-Teacher On-Policy Distillation
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Open-MOPD improves multi-teacher distillation by fixing token-level budget misallocation, raising capability recovery from 35.6% to 83.4% on SmolLM3.
- Why it matters
- Matters for engineers combining multiple specialized RL models into one generalist student model with dense reward supervision.
- Watch out
- Evaluation limited to SmolLM3-3B with oracle routing; real-world performance with imperfect routing decisions remains undemonstrated.
