AI can reason like a doctor, study says

Artificial intelligence that can "reason" is now capable of diagnosing real-life medical scenarios as well as or better than physicians, according to the results of a study published Thursday in Science.

The researchers used previously unknown clinical cases to test OpenAI's reasoning model o1 against the company's older model, GPT-4, as well as physicians and medical residents in training.

In a range of experiments, the o1 model often improved significantly on GPT-4's diagnostic ability and bested physicians, too.
