TimeBlind: A Spatio-Temporal Compositionality Benchmark for Video LLMs
Quick summary
arXiv:2602.00288v4 Announce Type: replace-cross Abstract: Fine-grained spatio-temporal understanding is essential for video reasoning and embodied AI. Yet, while Multimodal Large Language Models (MLLMs) master static semantics, their grasp of temporal dynamics remains brittle. We present TimeBlind, a diagnostic benchmark for compositional spatio-temporal understanding. Inspired by cognitive science, TimeBlind categorizes fine-grained temporal understanding into three levels: recognizing atomic events, characterizing event properties, and reasoning about event interdependencies. Unlike benchmar

Why it matters
“TimeBlind: A Spatio-Temporal Compositionality Benchmark for Video LLMs” highlights the need for repeatable measurement rather than a single impressive demonstration. Independent validation across datasets and clearly stated limitations determine whether a result can guide product decisions.
