Predicting the future of complex social systems has always been the ultimate challenge for enterprises and policymakers. Traditional models rely on top-down equations, but human society operates from the bottom up. Enter WorldSim, an AI-driven parallel world simulation that fundamentally shifts the paradigm. Instead of static formulas, WorldSim leverages a million-scale multi-agent system to simulate social evolution. Today, we are pulling back the curtain to reveal the technical architecture that makes this large-scale emergent simulation possible. 1. The Architecture of Agent Genesis: Autonomous Personalities & Memory At the core of WorldSim is its world-building capability. Constructing a parallel society isn't just about spawning avatars; it requires cognitive autonomy. WorldSim automatically generates thousands to millions of AI Agents from real-world data.…
