LLMs Claude Fable 5.1 and GPT-6 Astra lag behind older CNN in skin lesion diagnosis

A dermatologist compared the diagnostic accuracy of two large language models, GPT-6 Astra and Claude Fable 5.1, against a 2015 Google image network on 200 biopsy-proven skin lesions. The older Google network achieved 62% accuracy, while both LLMs scored 42%. This study, with publicly available data and code, highlights the limitations of current LLMs in medical diagnosis, as the CNN would have missed 18 of 30 melanomas at its set threshold. AI

IMPACT Current LLMs show limited diagnostic accuracy in dermatology compared to older specialized models, indicating a need for further development in medical AI applications.
