DALPHIN (Independent) - Open Questions: leaderboard
Case-specific free-response questions written by the contributing pathologists for 285 cases of the DALPHIN pathology copilot benchmark (Lems et al., 2026). Answers are compared with the reference answer by BioBERT semantic similarity; higher is better. Independent scenario: every question is sent as a standalone query without earlier answers.
Metric: BioBERT semantic similarity (biomedical sentence-embedding similarity, at most 1) of the uncurated free-text answer to the contributing pathologist's reference answer (285 case-specific free-response questions; independent scenario: each question asked as a standalone query). Source: arxiv.org. Saturation forecast: Around February 2027. 3 models tracked.
