CIPHER Cross-Record Inference - MIMIC (Zero-Shot): leaderboard

Cross-record inference over privacy-hardened MIMIC clinical records with redacted narratives, from CIPHER (Roy Chowdhury et al., 2026): expert-validated questions combine structured fields with free-text narratives across 39 to 42 supplied records, answered with zero-shot prompting. Harmonic answer score in percent, the per-question harmonic mean of token overlap and Gemini 2.5 Flash acceptance; higher is better.

Metric: Harmonic answer score (%; per question the harmonic mean of token overlap with the reference and Gemini 2.5 Flash semantic acceptance, zero when rejected, averaged; MIMIC clinical records with redacted narratives; the full support-controlled context of 39-42 records including distractors; zero-shot prompting; greedy decoding). Source: arxiv.org. Saturation forecast: Around August 2027. 5 models tracked.
