It comes as no surprise that "ChatGPT struggles to answer medical questions"
"ChatGPT provided accurate responses to only about 10 of the questions, or about a quarter of the total. For the other 29 prompts, the answers were incomplete or inaccurate, or they did not address the questions."
"Those queries, they found, often yielded inaccurate – or even dangerous – responses."
