LongVidSearch - State Mutation (2-Hop): leaderboard
Metric: Accuracy (%) on the 238 State Mutation questions that need exactly 2 evidence clips, judged against the reference by exact match or by majority vote of three LLM judges (GPT-5, Gemini 3 Pro, GPT-4o); the backbone drives a fixed VideoAgent-style framework that retrieves clips and reads their captions through a standard tool interface; higher is better. Source: arxiv.org. Saturation forecast: Around July 2027. 10 models tracked.
