新基准揭示视频大模型在时间理解方面存在困难

研究人员开发了TimeBlind,一个旨在测试视频大语言模型(LLMs)时空理解能力的新基准。该基准采用最小对范式,呈现视觉上相同但仅在时间结构上有所不同的视频,以将时间推理与静态视觉线索区分开来。评估显示,即使是GPT-5和Gemini 3 Pro等先进模型,表现也差强人意,准确率仅为48.2%,而人类的准确率为98.2%,这表明模型严重依赖视觉捷径而非真正的时间逻辑。 AI

影响 突出了当前视频大模型能力的一个关键差距,可能会推动未来研究朝着更强大的时间推理方向发展。

    TimeBlind: 视频大语言模型的时空组合性基准测试

    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…
