Mutual-Taught for Co-adapting Policy and Reward Models

Tianyuan Shi, Canbin Huang, Fanqi Wan +5

During the preference optimization of large language models (LLMs), distribution shifts may arise between newly generated model samples and the data used to train the reward model…

ThinkSwitcher: When to Think Hard, When to Think Fast

Guosheng Liang, Longguang Zhong, Ziyi Yang +1

Large reasoning models (LRMs) excel at solving complex tasks by leveraging long chain-of-thought (CoT) reasoning. However, this often leads to overthinking on simple tasks, resulti…

FuseChat-3.0: Preference Optimization Meets Heterogeneous Model Fusion

Ziyi Yang, Fanqi Wan, Longguang Zhong +3

We introduce FuseChat-3.0, a suite of large language models (LLMs) developed by integrating the strengths of heterogeneous source LLMs into more compact target LLMs. Our source mod…

Weighted-Reward Preference Optimization for Implicit Model Fusion

Ziyi Yang, Fanqi Wan, Longguang Zhong +2

While fusing heterogeneous open-source LLMs with varying architectures and sizes can potentially integrate the strengths of different models, existing fusion methods face significa…

FuseChat: Knowledge Fusion of Chat Models

Fanqi Wan, Longguang Zhong, Ziyi Yang +2

While training large language models (LLMs) from scratch can indeed lead to models with distinct capabilities and strengths, it incurs substantial costs and may lead to redundancy…

Knowledge Fusion of Chat LLMs: A Preliminary Technical Report

Fanqi Wan, Ziyi Yang, Longguang Zhong +3

Recently, FuseLLM introduced the concept of knowledge fusion to transfer the collective knowledge of multiple structurally varied LLMs into a target LLM through lightweight continu…
