LatticeMind: A Conflict-Aware Memory Primitive for Multi-Agent Systems

Heng Zhou, Lian Zhang, Yutao Fan +5

Multi-agent LLM systems often fail not for lack of candidate answers, but because they have no persistent mechanism for deciding which incompatible claim should currently be truste…

SciAgentGym: Benchmarking Multi-Step Scientific Tool-use in LLM Agents

Yujiong Shen, Yajie Yang, Zhiheng Xi +17

Scientific reasoning inherently demands integrating sophisticated toolkits to navigate domain-specific knowledge. Yet, current benchmarks largely overlook agents' ability to orches…

Scaling Behaviors of LLM Reinforcement Learning Post-Training: An Empirical Study in Mathematical Reasoning

Zelin Tan, Hejia Geng, Xiaohang Yu +14

While scaling laws for large language models (LLMs) during pre-training have been extensively studied, their behavior under reinforcement learning (RL) post-training remains largel…

Select-then-Solve: Paradigm Routing as Inference-Time Optimization for LLM Agents

Heng Zhou, Zelin Tan, Zhemeng Zhang +15

When an LLM-based agent improves on a task, is the gain from the model itself or from the reasoning paradigm wrapped around it? We study this question by comparing six inference-ti…

CoEnv: Driving Embodied Multi-Agent Collaboration via Compositional Environment

Li Kang, Yutao Fan, Rui Li +11

Multi-agent embodied systems hold promise for complex collaborative manipulation, yet face critical challenges in spatial coordination, temporal reasoning, and shared workspace awa…

Can RL Improve Generalization of LLM Agents? An Empirical Study

Zhiheng Xi, Xin Guo, Jiaqi Liu +11

Reinforcement fine-tuning (RFT) has shown promise for training LLM agents to perform multi-turn decision-making based on environment feedback. However, most existing evaluations re…
