CIPHER Cross-Record Inference - CFPB (Least-to-Most): leaderboard
Cross-record inference over privacy-hardened Consumer Financial Protection Bureau complaint 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 least-to-most decomposition 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; Consumer Financial Protection Bureau complaint records with redacted narratives; the full support-controlled context of 39-42 records including distractors; least-to-most decomposition prompting; greedy decoding).
