Individual Simulation
The core of individual simulation is to simulate specific individuals through agent-driven by large models. This simulation typically focuses on the personality, behavior patterns, etc., of individuals, without involving interactions among multiple agents. For example, simulating the reactions of a group of people with specific psychological traits in a particular context.
The architecture of individual simulation usually includes four core components: personal profiles, memory, planning, and action. Through these components, agents can simulate individual behavior patterns and respond in specific situations. For example, agents can store historical information through the memory module, helping them maintain consistency and continuity in future actions.

Scenario Simulation
In the real world, individuals do not exist in isolation; they often collaborate to complete tasks in specific scenarios. Scenario simulation organizes a group of agents to cooperate in a specific context, simulating human collective responses. For example, simulating human behavior in emergencies such as fires or earthquakes…
The key to scenario simulation lies in designing a multi-agent system, including constructing the scenario environment, defining agent roles, establishing organizational structures, and communication protocols. Through these designs, agents can interact in a specific scenario, exchanging and influencing each other, competing and cooperating, inheriting and mutating, thereby simulating human collective behavior.

Social Simulation
The goal of social simulation is to simulate more complex and diverse social behaviors, exploring social dynamics in the real world. Unlike scenario simulation, social simulation does not only focus on the completion of specific tasks but rather on how interactions among individuals lead to macro social phenomena. For example, social simulation can be used to study the spread of public opinion, economic fluctuations, and the formation of social norms.
The core of social simulation lies in constructing a diverse group of individuals and simulating interactions among individuals through networks, social influence mechanisms, etc. Through these interactions, researchers can observe how complex social phenomena emerge from individual behaviors.

Case Study of Social Simulation 1
The AI startup Altera developed “the world’s first intelligent agent civilization,” constructing a society composed of thousands of AI-driven agents in a game.
In this virtual world, the agents not only have unique names, specialties, and hobbies but also build social systems such as governments, police, and religious institutions, and even have their own currency trading system. With the support of GPT-4, these agents exhibit unprecedented collaborative abilities: they can fend off monster invasions, complete complex infrastructure tasks, and even simulate democratic parliaments and religious cultures from the real world. The developers incorporated elements of simulating the American election into this intelligent agent society, where the agents discussed and voted, simulating the election process between Trump and Harris.
Even more astonishing is that in the simulated society, the agents can not only complete tasks but also possess a certain degree of self-awareness and sense of responsibility. For instance, an agent named Olivia, originally a farmer responsible for supplying food to the community, was inspired by adventurers and developed the thought of “the world is so big, I want to see it.” After discussions with other agents, Olivia ultimately realized her responsibility and decided to continue serving the community. This highly humanized decision-making process demonstrates the potential of agents in a simulated society.

Case Study of Social Simulation 2
Researchers from Stanford University, the University of Washington, and Google DeepMind developed an AI agent capable of realistically simulating human behavior. They built these agent models by interviewing over 1,000 representative Americans. These agents can not only simulate individual responses but also exhibit behavior highly consistent with humans in multiple social science experiments.
This type of simulation system can serve as a virtual laboratory, helping to validate theories in economics, sociology, organizational studies, and political science. The system operates by combining detailed interview records with the GPT-4o model, establishing a “persona” and personality for each agent. When users ask questions to the agents, these agents with specific “personas” and personalities mimic the responses of the interviewees.
The research team designed multiple tests to evaluate the AI’s predictive capabilities regarding human behavior, covering the General Social Survey (GSS), the Big Five personality assessment, and several behavioral economics experiments. The results showed that AI based on interview data achieved an accuracy rate of up to 85% in predicting social survey (GSS) questions, far exceeding traditional statistical models.
Imagine if a larger-scale cluster of agents could be established, encompassing hundreds of millions of people, capable of simulating stock market changes and predicting stock price fluctuations?

The Potential and Challenges of Intelligent Agents Simulating Human Society
Large model-driven agents exhibit tremendous potential in simulating human society. Firstly, they can simulate the behaviors of a large number of individuals at a lower cost, avoiding the issues of requiring extensive human participation in traditional research. Secondly, large models can simulate complex individual decision-making processes through their powerful reasoning and planning capabilities, thus better understanding and predicting human behavior.
However, social simulation also faces several challenges. Firstly, ensuring the accuracy and authenticity of the simulation is a significant issue. Although large models can generate seemingly reasonable behaviors, whether these behaviors truly reflect human behavior in the real world still requires further validation. Secondly, as the scale of simulation expands, computing resources and time costs will also increase significantly, making it crucial to find a balance between precision and scale.

From Simulation to Decision Support
With the continuous advancement of large model technology, the application prospects of social simulation will become even broader. In the future, social simulation can not only be used for theoretical research but also provide support for practical decision-making in policy formulation and social management. For example, by simulating the impact of different policies on society, decision-makers can better assess the potential effects of policies, leading to more informed decisions.
In summary, large model-driven intelligent agents provide us with a new way to understand and simulate human society. From individuals to groups, and then to the entire society, this simulation method can not only help us unveil the mysteries of human society but also provide strong support for decision-making in the real world. This is the advanced application of intelligent agents.
