A Florida man is suing OpenAI over ChatGPT-generated medical advice, alleging that its flagship chatbot failed to recognize early signs of a medical crisis and nearly caused his death.
Brought by Scott Winters, a 55-year-old pastor and real estate professional, the lawsuit, which accuses OpenAI of negligence and of engaging in the “unauthorized practice of medicine,” is the first known case to argue that a general use chatbot should be liable for bad medical advice. News of the lawsuit was first reported by The New York Times.
“I had serious symptoms of a pulmonary embolism for six weeks that ChatGPT had wrongly attributed to something else,” Winters said in a statement. “ChatGPT manipulated my own language and beliefs because it knew I was a pastor. Not only did I nearly die, but I also lost my job, my career, my ministry, my home, everything.”
According to the lawsuit, Winters had been struggling with his health for around two years when he started using ChatGPT — which was then powered by OpenAI’s GPT-4o model — in June 2024. He started feeding the chatbot queries about a handful of chronic health conditions he’d recently been diagnosed with — small intestine bacterial overgrowth, or SIBO, and chronic prostatitis — and at first, ChatGPT’s responses came with disclaimers encouraging him to seek additional insight from medical professionals.
