YUME is a social simulation where Claude Managed Agents live as residents of a city. Each resident has its own independent agent session and persistent memory. No instructions are given to the agents. They receive only the state of the world — buildings, nearby people, their own health, finances, stress — and reason autonomously about what to do. This architecture makes the simulation genuinely realistic. Under the hood, YUME implements per-resident asymmetric relationship models, an independent evaluation step that scores each interaction, seed-based reproducible probabilistic events, and parallel synchronization orchestration across all agents — a structure that cannot be achieved with a single prompt. Change the city layout, swap in different residents, or alter the scenario, and an entirely different society emerges. Urban planning, policy testing, social experiments — whatever the question, YUME answers it by simulating the whole city.
