Researchers have developed COMET, a new framework designed to enhance video multimodal large language models by improving their understanding of fine-grained motion and temporal reasoning. The framework introduces a dedicated temporal motion branch and integrates its findings into the appearance stream via cross-attention mechanisms. COMET also employs a novel optimization strategy that leverages temporal order as a direct learning signal, leading to significant performance gains on action-centric and temporal reasoning tasks across different model architectures like Qwen3-VL-8B and InternVL2.5-8B.
