EdgeWise: Bringing Long-Horizon Agents to the Edge via Selective Cloud Delegation

Zeru Shi, Jindong Jiang, Ryo Hachiuma +10

Complex and long-horizon agent tasks often rely on frontier models deployed in the cloud to achieve strong performance. However, using these models for every step of a long-horizon…

Dream2Discern: Learning from Hard Latent Variants for Runtime Failure Prediction in Multi-Agent Systems

Boxuan Zhang, Jianing Zhu, jianing Zhu +2

Reliable deployment of LLM-based multi-agent systems calls for runtime auditors that predict terminal outcomes from observed execution prefixes. These auditors typically learn from…

COUNTERMEM: World-Model Verified Counter-Factual Memory for Language Agents

Hongji Pu, Ruixiang Tang, Yongfeng Zhang

Existing agent memory frameworks mainly create memory through an agent's interaction with the factual world, e.g., remembering feedback from actions taken to improve performance on…

TRACES: Proactive Safety Auditing for Multi-Turn LLM Agents via Trajectory-State Modeling

Jiaqian Li, Yanshu Li, Boxuan Zhang +2

LLM agents increasingly operate through multi-turn tool use and environment interaction, where safety risks often emerge from intermediate steps long before they surface in the fin…

MemEye: A Visual-Centric Evaluation Framework for Multimodal Agent Memory

Minghao Guo, Qingyue Jiao, Zeru Shi +14

Long-term agent memory is increasingly multimodal, yet existing evaluations rarely test whether agents preserve the visual evidence needed for later reasoning. In prior work, many…

AgentForesight: Online Auditing for Early Failure Prediction in Multi-Agent Systems

Boxuan Zhang, Jianing Zhu, Zeru Shi +2

LLM-based multi-agent systems are increasingly deployed on long-horizon tasks, but a single decisive error is often accepted by downstream agents and cascades into trajectory-level…

A Single Layer to Explain Them All:Understanding Massive Activations in Large Language Models

Zeru Shi, Zhenting Wang, Fan Yang +2

We investigate the origins of massive activations in large language models (LLMs) and identify a specific layer named the \textbf{Massive Emergence Layer (ME Layer)}, that is consi…

From Rebound to Remedy: Understanding and Mitigating Reward Hacking via Representation Engineering

Rui Wu, Ruixiang Tang

Reinforcement learning for LLMs is vulnerable to reward hacking, where models exploit shortcuts to maximize reward without solving the intended task. We systematically study this p…
