What is HealthBench?
HealthBench is an OpenAI benchmark with 5,000 realistic health conversations, written and graded with input from physicians. Models answer medical questions and the responses are scored on accuracy, completeness, context awareness and communication quality — including knowing when to refer to a professional.
What does it test?
HealthBench measures broad everyday usefulness across domains. In detail, it checks:
- accurate medical knowledge in real dialogue situations
- recognising emergencies and advising a doctor visit
- tailoring answers to the patient's actual situation
- clear communication instead of technical jargon
How to read the score
The score is accuracy: the percentage of tasks answered or solved correctly. 100% means every task was solved perfectly; higher is better.
