As large language models (LLMs) are increasingly deployed as intelligent agents to participate in collaborative tasks, an important yet under-explored question emerges: How do the beliefs of multiple LLMs form, spread, and evolve when they interact in social networks? Traditional single-agent reasoning research cannot answer this question, as the group dynamics introduced by social interactions are fundamentally different from isolated reasoning.
CoevolveSim is designed to fill this research gap. It is an agent-based simulation framework specifically for studying the process of belief co-evolution among LLMs with different roles and professional backgrounds in social networks. Developed by a research team at Northeastern University, this framework has been open-sourced as a supporting codebase for an academic paper.
