A Training-Free Framework for Long Video Understanding via Video-Query-Options Similarity

ICLR 2026poster

Multimodal Large Language Models (MLLMs) have achieved remarkable success in image and short video understanding tasks, but their performance on hour-long videos remains limited due to constraint of input token capacity. Existing approaches often require costly training procedures, hindering their a…

LiViBench: An Omnimodal Benchmark for Interactive Livestream Video Understanding

AAAI 2026technical

The development of multimodal large language models (MLLMs) has advanced general video understanding. However, existing video evaluation benchmarks primarily focus on non-interactive videos, such as movies and recordings. To fill this gap, this paper proposes the first omnimodal benchmark for intera
