Will GPT-5, Claude, Gemini Break Doctors’ Monopoly On Medical Expertise?

A recent Stanford study found that GPT-4 achieved a median diagnostic score of 92% on clinical vignettes compared to 74% for physicians, even outperforming doctors who had AI assistance. Similarly, in a Mayo Clinic pilot, Google’s Med-PaLM 2 produced answers that specialists consistently rated as safe and, in many cases, superior to physician-written responses.The next opportunity for genAI is shifting from research into practice, with patients using large language models to help manage aspects of care once reserved for physicians. Unlike “Dr. Google,” which buried users in dozens of links of questionable validity, genAI delivers true expertise: it synthesizes medical evidence and provides personalized, clear guidance to individuals in their preferred language.
