MOPD: Multi-Teacher On-Policy Distillation for Capability Integration in LLM Post-Training

Wenhan Ma, Jianyu Wei, Liang Zhao +10

Modern large language models (LLMs) rely on reinforcement learning during post-training to push specific capabilities, yet integrating multiple capabilities into one model remains…

Teaching Large Language Models to Maintain Contextual Faithfulness via Synthetic Tasks and Reinforcement Learning

Shuzheng Si, Haozhe Zhao, Cheng Gao +11

Teaching large language models (LLMs) to be faithful in the provided context is crucial for building reliable information-seeking systems. Therefore, we propose a systematic framew…

PyramidKV: Dynamic KV Cache Compression based on Pyramidal Information Funneling

Zefan Cai, Yichi Zhang, Bofei Gao +8

In this study, we investigate whether attention-based information flow inside large language models (LLMs) is aggregated through noticeable patterns for long context processing. Ou…
