Researchers have introduced ReTool-Video, a novel approach for video understanding agents that enhances their reasoning capabilities. This method utilizes an expanded tool library with 134 specialized tools, including meta-tools for filtering and aggregation, to support fine-grained compositional reasoning. ReTool-Video recursively breaks down high-level video intents into executable tool chains, allowing for dynamic parameter repair and tool substitution to achieve complex multimodal operations. Experiments show ReTool-Video outperforms existing baselines on several video understanding benchmarks. AI
