OAKS-BABI (RAG) - Sparse Changes: leaderboard
Metric: Interval-level accuracy (%) on OAKS-BABI (1,224 questions over bAbI-style synthetic stories whose facts change across 2K-token chunks), questions whose answer changes sparsely: the same questions are asked after every chunk and each answer is scored against the answer valid at that point, averaged over intervals and questions; RAG setting (top 30 earlier chunks retrieved with Qwen3-Embedding-0.6B); higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 13 models tracked.
