VGenST-Bench

General AIMultimodal PerceptionSungkyunkwan University

VGenST-Bench evaluates spatio-temporal reasoning in multimodal large language models using 1,200 procedurally generated videos with controlled scene composition, camera trajectory, and reasoning targets. It covers 12 reasoning tasks across three spatial scales and 12 QA types across three reasoning levels, with multiple choice and open-ended question variants.

Why it matters

Existing video reasoning benchmarks rely on static or passively curated content, limiting fine-grained diagnosis. VGenST-Bench uses active synthesis to enable controlled and diverse evaluation of fine-grained spatio-temporal reasoning, supporting model comparison and targeted improvement in MLLMs.

Motivation

Spatio-temporal reasoning is a core capability for Multimodal Large Language Models (MLLMs) operating in the real world.
