Researchers have introduced FineBench, a new benchmark designed to evaluate the fine-grained human activity understanding capabilities of vision-language models (VLMs). The benchmark includes over 199,000 question-answer pairs across 64 long-form videos, focusing on detailed actions, interactions, and object manipulations. Evaluations showed that while proprietary models like GPT-5 perform well, open-source VLMs struggle with spatial reasoning and distinguishing subtle human movements. To address these limitations, the team also proposed FineAgent, a modular framework aimed at enhancing VLM performance on such tasks. AI
