PA1-OPD: One-Step Prefix-Augmented On-Policy Distillation for Language Model Pretraining

Knowledge distillation (KD) improves language-model pretraining by matching teacher distributions at corpus prefixes, but provides no direct supervision at contexts induced by student predictions. We introduce PA1-OPD, which augments corpus-path distillation with teacher feedback after one student-sampled transition pe...

Cache-Aware Joint Router Adaptation for Memory-Efficient MoE Inference

This work formulate expert-cache management as a model-side algorithmic problem and proposes cache-aware post-training that jointly adapts the MoE backbone and lightweight auxiliary routers while preserving the native inference-time Top-K rule.
