PlanGPT: Enhancing Urban Planning with Tailored Language Model and Efficient Retrieval
It addresses inefficiencies for urban planners by providing a domain-specific tool, though it appears incremental as it builds on existing methods with fine-tuning and retrieval.
The paper tackles the problem of general-purpose large language models struggling with urban planning tasks by introducing PlanGPT, a specialized model that achieves advanced performance and delivers superior quality responses tailored to urban planning.
In the field of urban planning, general-purpose large language models often struggle to meet the specific needs of planners. Tasks like generating urban planning texts, retrieving related information, and evaluating planning documents pose unique challenges. To enhance the efficiency of urban professionals and overcome these obstacles, we introduce PlanGPT, the first specialized Large Language Model tailored for urban and spatial planning. Developed through collaborative efforts with institutions like the Chinese Academy of Urban Planning, PlanGPT leverages a customized local database retrieval framework, domain-specific fine-tuning of base models, and advanced tooling capabilities. Empirical tests demonstrate that PlanGPT has achieved advanced performance, delivering responses of superior quality precisely tailored to the intricacies of urban planning.
