AgentSociety: Large-Scale Simulation of LLM-Driven Generative Agents Advances Understanding of Human Behaviors and Society
This paper introduces AgentSociety, a groundbreaking large-scale social simulator leveraging LLM-driven generative agents, a realistic societal environment, and a powerful simulation engine. By enabling bottom-up simulations, AgentSociety offers a scalable, replicable, and systematic computational approach to studying complex social dynamics, overcoming limitations of traditional experiments. It generates social lives for over 10,000 agents, facilitating 5 million interactions, and validates its authenticity by reproducing patterns from real-world social experiments across diverse issues like polarization and the impact of external shocks. This marks a significant paradigm shift for computational social science.

LLM-Driven Social Generative Agents
AgentSociety's core lies in its sophisticated LLM-driven agents, endowed with human-like minds encompassing emotions, needs, and cognition. These internal states dynamically drive behaviors like mobility, employment, consumption, and social interactions, integrating theories from psychology, economics, and behavioral science.
The system goes beyond simple role-playing by incorporating agentic modules for memory, reflection, and action, ensuring coherent and context-aware responses. It models a continuous feedback loop where agents adapt their actions based on evolving cognitive states, past experiences, and environmental context.
Realistic Societal Environment
A realistic societal environment is crucial for authentic human behavior simulation. AgentSociety constructs a multifaceted virtual world comprising Urban, Social, and Economic spaces. The Urban Space includes road networks (OpenStreetMap), Points of Interest (POIs), and supports multi-modal mobility (driving, walking, public transit, taxi services) with real-time feedback.
The Social Space models agents' social networks, online/offline interactions, and even a "supervisor" for content moderation. The Economic Space simulates macroeconomics, including firms, governments, and banks, with dynamic wages, prices, taxation, and interest rates, all based on real-world data and principles.
Powerful Large-Scale Simulation Engine
AgentSociety employs a robust simulation engine designed for large-scale interactions and high computational efficiency. It leverages distributed computing via the Ray framework and an MQTT-powered messaging system, enabling asynchronous, multi-process parallel execution for up to 10k agents and millions of daily interactions.
The engine includes essential utilities such as LLM API adapters (supporting various LLMs), retry mechanisms, JSON parsers, and a comprehensive logging/metric recording system (mlflow, PostgreSQL). A GUI facilitates experiment management, real-time monitoring, and direct interaction with agents through surveys and interviews.
Performance Evaluation & Scalability
AgentSociety demonstrates strong performance and scalability across various experiments. The societal environment effectively handles high concurrency tasks from massive agents, showing minimal performance degradation even with 10^6 individuals.
The MQTT-powered messaging system achieves a throughput of 44,702.1 msg/s, making it suitable for large-scale agent communication, outperforming RabbitMQ and offering built-in GUI tools. While LLM API calls remain a primary bottleneck, the group-based asynchronous execution significantly reduces overall execution time, making large-scale simulations feasible and efficient.
Exemplary Social Experiments
The simulator serves as a valuable testbed for computational social experiments, covering key social issues. Experiments on polarization demonstrate how homophilic interactions intensify divisions, while heterogeneous interactions foster moderation. Studies on inflammatory message spread reveal their viral potential and the effectiveness of node-level interventions.
Furthermore, AgentSociety explores the impact of Universal Basic Income policies on consumption and depression levels, aligning with real-world observations. It also simulates external shocks like hurricanes, accurately replicating human mobility responses to extreme weather events, validating its authenticity for policymakers and social scientists.

Case Study: Simulating External Shocks of Hurricane
Context: Understanding human mobility patterns during natural disasters like hurricanes is crucial for emergency response. This study used AgentSociety to simulate Hurricane Dorian's impact on Columbia, South Carolina, focusing on 1,000 agents with real-time weather updates.
Methodology: The experiment evaluated mobility through two metrics: Activity Level (visualized via spatial distribution maps) and Total Daily Trips (a 9-day normalized time-series). Agents dynamically adjusted plans based on environmental information.
Key Findings: Simulation results showed a sharp decrease in activity levels (to ~30%) during landfall, followed by a gradual return to normal, mirroring real-world data. The simulated daily trips closely followed actual patterns, demonstrating AgentSociety's ability to replicate human-like responses to extreme weather events.
Impact: This validation underscores the simulator's potential as a tool for analyzing human behavior under external shocks, providing valuable insights for improved disaster preparedness and response strategies for both social scientists and policymakers.
