Social Gym and SPaRTan: Benchmarking and Improving LLM Social Reasoning via Multi-Agent Game Tournaments

Keyu He, Xuhui Zhou, Maarten Sap

LLM agents are increasingly deployed in multi-agent social settings where they must cooperate, negotiate, and adapt to other agents. Measuring and improving these social skills is…

Reinforcing Human Behavior Simulation via Verbal Feedback

Weiwei Sun, Xuhui Zhou, Jiarui Liu +13

Humans learn social norms and behaviors from verbal feedback (e.g., a parent saying "that was rude" or a friend explaining "here's why that hurt"). Yet, learning from feedback for…

CodeScout: An Effective Recipe for Reinforcement Learning of Code Search Agents

Lintang Sutawika, Aditya Bharat Soni, Bharath Sriraam R R +8

A prerequisite for coding agents to perform tasks on large repositories is code localization - the identification of relevant files, classes, and functions to work on. While reposi…

Mind the Sim2Real Gap in User Simulation for Agentic Tasks

Xuhui Zhou, Weiwei Sun, Qianou Ma +8

As NLP evaluation shifts from static benchmarks to multi-turn interactive settings, LLM-based simulators have become widely used as user proxies, serving two roles: generating user…
