Original analysis / HealthBench Professional Guide

Read the benchmark closely.

HealthBench Professional combines physician-authored tasks, deliberate difficulty selection and a length-adjusted rubric score. Those choices make its number useful for a particular kind of comparison. This publication explains the sampling, shows historical same-model system results and makes the adjustment formula interactive. Read the benchmark dossier, inspect the calculator and use the guides to separate measured performance from broader clinical claims. Arcophos publishes independent analysis; OpenAI and the original research team created the benchmark.
