Critique-RL: Training Language Models for Critiquing through Two-Stage Reinforcement Learning

Zhiheng Xi, Jixuan Huang, Xin Guo +15

Training critiquing language models to assess and provide feedback on model outputs is a promising way to improve LLMs for complex reasoning tasks. However, existing approaches typ…

Scaling Long-Horizon LLM Agent via Context-Folding

Weiwei Sun, Miao Lu, Zhan Ling +4

Large language model (LLM) agents are fundamentally constrained by context length on long-horizon tasks. We introduce Context-Folding, a framework that empowers agents to actively…

Scaling LLM Multi-turn RL with End-to-end Summarization-based Context Management

Miao Lu, Weiwei Sun, Weihua Du +4

We study reinforcement learning (RL) fine-tuning of large language model (LLM) agents for long-horizon multi-turn tool use, where context length quickly becomes a fundamental bottl…

ToolHop: A Query-Driven Benchmark for Evaluating Large Language Models in Multi-Hop Tool Use

Junjie Ye, Zhengyin Du, Xuesong Yao +11

Effective evaluation of multi-hop tool use is critical for analyzing the understanding, reasoning, and function-calling capabilities of large language models (LLMs). However, progr…
