LangMARL: Natural Language Multi-Agent Reinforcement Learning

Huaiyuan Yao, Longchao Da, Xiaoou Liu +3

Large language model (LLM) agents struggle to autonomously evolve coordination strategies in dynamic environments, largely because coarse global outcomes obscure the causal signals…

Chimera: Latency- and Performance-Aware Multi-agent Serving for Heterogeneous LLMs

Kangqi Ni, Wenyue Hua, Xiaoxiang Shi +3

Multi-agent applications often execute complex tasks as multi-stage workflows, where each stage is an LLM call whose output becomes part of context for subsequent steps. Existing L…

Farther the Shift, Sparser the Representation: Analyzing OOD Mechanisms in LLMs

Mingyu Jin, Yutong Yin, Jingcheng Niu +7

In this work, we investigate how Large Language Models (LLMs) adapt their internal representations when encountering inputs of increasing difficulty, quantified as the degree of ou…

TMS: Trajectory-Mixed Supervision for Reward-Free, On-Policy SFT

Rana Muhammad Shahroz Khan, Zijie Liu, Zhen Tan +2

Reinforcement Learning (RL) and Supervised Fine-Tuning (SFT) are the two dominant paradigms for enhancing Large Language Model (LLM) performance on downstream tasks. While RL gener…

DOGe: Defensive Output Generation for LLM Protection Against Knowledge Distillation

Pingzhi Li, Zhen Tan, Mohan Zhang +3

Large Language Models (LLMs) represent substantial intellectual and economic investments, yet their effectiveness can inadvertently facilitate model imitation via knowledge distill…

The Quest for Efficient Reasoning: A Data-Centric Benchmark to CoT Distillation

Ruichen Zhang, Rana Muhammad Shahroz Khan, Zhen Tan +3

Data-centric distillation, including data augmentation, selection, and mixing, offers a promising path to creating smaller, more efficient student Large Language Models (LLMs) that…
