# Harvard study: AI beat two doctors at emergency room diagnoses

> OpenAI's o1 gave the exact or near diagnosis in 67% of ER cases at triage, versus 55% and 50% for two physicians, in a study published in Science.

## The study
Researchers from **Harvard Medical School** and **Beth Israel Deaconess Medical Center** published a study in **Science**. They compared diagnoses from two internal medicine attending physicians with OpenAI's **o1** and **4o** models across **76 emergency room patients**.

## Results at initial triage
| Who | Exact or very close diagnosis |
|---|---|
| OpenAI o1 | 67% |
| Physician 1 | 55% |
| Physician 2 | 50% |

## Caveats
- Only text-based inputs were tested, no images or exams.
- The authors stress an "urgent need for prospective trials to evaluate these technologies in real-world patient care settings."

AI is not replacing doctors yet, but it could become a strong assistant.
