CityBehavEx: A Scalable and Empirically Validated LLM-Assisted Urban Simulation Platform
Gustavo H. Santos, Aline Viana, Thiago H Silva
Recent LLM-based multi-agent urban simulators can generate semantically rich city routines, but they remain costly to scale and are often weakly validated against empirical mobilit…
When Plausible Is Not Realistic: Evaluating Human Mobility in LLM-Based Urban Simulation
Gustavo H. Santos, Aline Carneiro Viana, Thiago H. Silva
LLM-based generative agents are increasingly used in urban simulators, yet it remains unclear whether they reproduce empirically realistic human mobility patterns or merely generat…
Stable Behavior, Limited Variation: Persona Validity in LLM Agents for Urban Sentiment Perception
Neemias B da Silva, Rodrigo Minetto, Daniel Silver +1
Large Language Models (LLMs) are increasingly used as proxies for human perception in urban analysis, yet it remains unclear whether persona prompting produces meaningful and repro…
Persona Prompting in Multimodal Urban Perception: Descriptive Convergence and Interpretive Variation
Neemias da Silva, Matt Ratto, Myriam Delgado +3
This study examines how persona prompting shapes language generated by two multimodal large language models in urban perception, a setting for examining subjective interpretations…
