• Abstract summary: We simulate a networked system involving thousands of large language model agents, discovering their social interactions, result in human-like polarization. Similarities between humans and LLM agents raise concerns about their capacity to amplify societal polarization, but also hold the potential to serve as a valuable testbed for identifying plausible strategies to mitigate it.

• Abstract: Rapid advances in large language models (LLMs) have empowered autonomous agents to establish social relationships, communicate, and form shared and diverging opinions on political issues. Our understanding of their collective behaviours and underlying mechanisms remains incomplete, however, posing unexpected risks to human society. In this paper, we simulate a networked system involving thousands of large language model agents, discovering their social interactions, guided through LLM conversation, result in human-like polarization. We discover that these agents spontaneously develop their own social network with human-like properties, including homophilic clustering, but also shape their collective opinions through mechanisms observed in the real world, including the echo chamber effect. Similarities between humans and LLM agents -- encompassing behaviours, mechanisms, and emergent phenomena -- raise concerns about their capacity to amplify societal polarization, but also hold the potential to serve as a valuable testbed for identifying plausible strategies to mitigate polarization and its consequences.

  We propose AgentSociety, a large-scale social simulator that integrates a realistic societal environment. Based on the proposed simulator, we generate social lives for over 10k agents, simulating their 5 million interactions. We focus on four key social issues: polarization, the spread of inflammatory messages, the effects of universal basic income policies, and the impact of external shocks such as hurricanes.

  Large language model (LLM) agents have gained traction as simulation tools for modeling human behavior. We introduce TwinMarket, a novel multi-agent framework that leverages LLMs to simulate socio-economic systems. Our approach provides valuable insights into the complex interplay between individual decision-making and collective socio-economic patterns.

  Large language models (LLMs)-based AI agents have made significant progress, enabling them to achieve human-like intelligence. We present LMAgent, a very large-scale and multimodal agents society based on multimodal LLMs. In LMAgent, besides chatting with friends, the agents can autonomously browse, purchase, and review products, even perform live streaming e-commerce.

  Large Language Models (LLMs) have created new disruptive possibilities for persuasive communication. In areas such as politics, marketing, public health, e-commerce, and charitable giving, such LLM Systems have already achieved human-level or even super-human persuasiveness. Our survey suggests that the current and future potential of LLM-based persuasion poses profound ethical and societal risks.

  We investigate the dynamics of conventions within populations of Large Language Model (LLM) agents using simulated interactions. We show that globally accepted social conventions can spontaneously arise from local interactions between communicating LLMs. Minority groups of committed LLMs can drive social change by establishing new social conventions.

  This paper probes the collaboration mechanisms among contemporary NLP systems by practical experiments with theoretical insights. We fabricate four unique societies' comprised of LLM agents, where each agent is characterized by a specific trait' (easy-going or overconfident) and engages in collaboration with a distinct thinking pattern' (debate or reflection) Our results further illustrate that LLM agents manifest human-like social behaviors, such as conformity and consensus reaching, mirroring social psychology theories.
