Description: Researchers created Moment-Video, a benchmark testing whether video models can reliably understand brief, answer-critical visual events. They tested 34 MLLMs and found that top models achieve only 39.6% accuracy, with most open-source models scoring below 25%. This shows current video AI struggles to capture short, transient visual evidence effectively.
