HealthBench
OpenAI benchmark of 5,000 realistic health conversations graded against physician-written rubrics. LLMReference tracks the length-adjusted score when available to reduce verbosity bias. High benchmark score alone doesn't make a model the right pick — weigh it against pricing, API availability, and release date.

How to read this benchmark
This benchmark scores models where higher is better. Scores are useful for directional filtering and shortlisting — not for universal quality ranking. Prefer benchmarks closest to your workload, then validate the linked model pages for pricing, context window, and provider availability.
Trust this score when
- There is a fresh timestamped snapshot (or multiple snapshots) for this benchmark.
- The model list covers the same version family you can actually deploy today.
- Top candidates overlap with your required routing and feature requirements.
Be cautious when
- There is only one benchmark snapshot or the dataset appears stale.
- The benchmark metric direction is opposite of your decision objective.
- The score difference between options is narrow and likely within implementation variance.
