AgenticCity-Bench: Longitudinal Multimodal Observations of Urban Dynamics with Agentic Reasoning

AgenticCity-Bench is a longitudinal multimodal benchmark that unifies state modeling and agentic reasoning for urban dynamics. It covers 16 cities across 12 countries from 2000 to 2025, providing 18 modalities that capture urban function, activity, and environmental state. The benchmark aligns heterogeneous data around a common spatial reference and calendar index, enabling cross‑modal translation and diverse agentic city tasks such as forecasting, planning, and resource analysis.

CityReal: Human-Aligned Urban Behavior and City Dynamics Simulation with Large-Scale LLM Agents

CityReal is a modular framework that uses large language model agents to simulate human-aligned urban behavior. It models agents as intention-driven decision makers who pursue coherent mobility and activity plans, learning habits and preferences over time. By training textual adapters to align agent decisions with observed population statistics, CityReal improves realism at both micro and macro levels and can scale to tens of thousands of agents for analyzing crowd density, place popularity, mobility flows, and well‑being under various urban scenarios.
