LongMedBench - Visit Cloze: 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: reinsert masked, timestamped events of one visit into their original positions, 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 6,776 items; visit cloze: reinsert masked, timestamped intervention events of one visit into their original positions; MIMIC-IV patients with long multi-visit event streams; naive long-context agent, provider default configuration). Source: arxiv.org. Saturation forecast: Estimated already saturated. 4 models tracked.
