 STBench is a benchmark to evaluate the ability of large language models in spatio-temporal analysis. This benchmark consists of 13 distinct tasks and over 60,000 question-answer pairs, covering four dimensions: knowledge comprehension, spatio-temporal reasoning, accurate computation and downstream applications.
