AI Chatbots Fail 50% of Medical Queries in New Study

A study in BMJ Open found five AI chatbots provide poor medical advice half the time ^[1][2]. Researchers evaluated responses to health queries and found 50% were inaccurate or incomplete ^[1]. These findings raise concerns about the reliability of artificial intelligence for health information ^[3]. The audit also highlighted frequent hallucinations where the chatbots invented scientific citations ^[1]. These tools often provided links or references to studies that do not exist ^[2]. Experts warn that these systems are not suitable for clinical decision-making or self-diagnosis ^[3].
