LongMedBench - Joint Sorting: leaderboard
LongMedBench (2026) builds long multi-visit patient histories from MIMIC-IV records to test medical agents on retrieval, temporal reasoning and clinical decisions over long horizons. Temporal reasoning: pair admission and discharge fragments of five visits and order them in time, scored by mean Kendall tau from -1 to 1; higher is better.
Metric: Mean Kendall tau (-1 to 1; agreement between the ordering given by the model and the true chronological order, averaged over 2,878 items; joint sorting: pair ten admission and discharge fragments of five visits and order them in time; MIMIC-IV patients with long multi-visit event streams; naive long-context agent, provider default configuration). Source: arxiv.org. Saturation forecast: Around February 2027. 4 models tracked.
