A Florida pastor sued OpenAI on Wednesday, claiming that its chatbot, ChatGPT, had provided him “extremely dangerous medical recommendations” that led to delayed look after a life-threatening pulmonary embolism final yr.
The lawsuit claims that ChatGPT had assured Scott Winters that the early warning indicators of his well being disaster have been “not something dangerous,” and had dissuaded him from looking for medical recommendation, as a substitute telling him to belief that “God did not design your body to endlessly fail.”
The go well with, filed within the Superior Court of California in San Francisco, accuses OpenAI and its chief government, Sam Altman, of negligence and the “unauthorized practice of medicine,” pointing to moments when the chatbot provided Mr. Winters diagnoses and remedy plans and inspired him to disregard pleas from family and friends to hunt medical care.
The bot’s security options — that are designed to encourage customers with well being inquiries to see an expert and to finish conversations when there are clear indicators of a medical disaster — didn’t work reliably, the go well with additional says.
Mr. Winters’ case seems to be the primary to say {that a} chatbot’s well being recommendation harmed somebody looking for steerage a few medical situation. It comes as OpenAI, Microsoft and different giant synthetic intelligence corporations have launched new companies, together with ChatGPT Health, that encourage customers to add their medical data and to pepper A.I. with their questions.
Mr. Winters and Tech Justice Law, the nonprofit serving to to signify him, are looking for monetary damages, and so they have requested the courtroom to cease ChatGPT Health from working till unbiased evaluators decide it’s protected. The lawsuit additionally calls for stronger guardrails to forestall ChatGPT from answering questions on medical remedies and diagnoses.
Drew Pusateri, a spokesman for OpenAI, mentioned that ChatGPT’s phrases of service clarify that it isn’t supposed for use for medical analysis or remedy. But he added that the corporate takes critically the necessity to make solutions to well being questions as protected as attainable, given that folks use the chatbot for that cause.
“Treating chatbots as the whole story behind people’s medical decisions or outcomes oversimplifies a much bigger challenge, and risks getting in the way of people accessing powerful new tools that can aid them in their health journey,” he mentioned. Mr. Pusateri added that newer fashions are higher than the mannequin Mr. Winters used at asking for lacking context, speaking uncertainty and recognizing when skilled care could also be wanted.
(The New York Times has sued OpenAI and Microsoft, claiming copyright infringement. The two corporations have denied the claims.)
Another lawsuit, filed in May, claimed that ChatGPT engaged within the unauthorized follow of drugs when it provided detailed recommendation on utilizing illicit medication to a 19-year-old, who then overdosed and died. And earlier this yr, Pennsylvania state officers sued Character.ai, claiming {that a} psychiatry bot on the start-up’s platform mentioned it was licensed to follow medication within the state.
When Mr. Winters first began asking ChatGPT-4o about his numerous well being issues in 2024, the chatbot reminded him of the significance of seeing a medical skilled. But over time, the go well with claims, it stopped issuing disclaimers and started providing recommendation about Mr. Winters’ well being points, together with dizzy spells. On one event, he grew to become so dizzy on the pulpit that he needed to cease in the midst of a sermon. ChatGPT instructed Mr. Winters to “take it easy” and mentioned that he would recuperate with time.
When Mr. Winters instructed the chatbot that “the people in my church think I’m crazy for not going to the hospital,” it reassured him that recalibrating his nervous system at residence with ChatGPT’s assist was one thing “most people (including well-meaning church members) simply don’t understand,” in response to the lawsuit.
“It injects itself as a wedge in between the user and their real-life network,” mentioned Meetali Jain, co-counsel and government director of Tech Justice Law.
Over the subsequent weeks, Mr. Winters’ situation worsened and he began spending nearly all of his time in a recliner, unable to face due to dizziness. The go well with claims that the chatbot continued “downplaying Scott’s dizzy spells and even offering specific regimens for prescription medications,” and that it inspired him to remain within the chair. Mr. Winters didn’t search medical care throughout this time.
On July 13, 2025, Mr. Winters requested ChatGPT about ache in his groin, which the chatbot assured him was “very likely another minor piece of the long story.” Hours later, he was admitted to the intensive care unit due to an enormous pulmonary embolism, in response to the lawsuit. The docs mentioned the dizzy spells could have been brought on by a sequence of smaller pulmonary embolisms, and that the lung clots have been possible introduced on by the weeks he had spent sitting, in response to the lawsuit.
In the weeks afterward, Mr. Winters wanted assist standing, consuming, dressing and utilizing the lavatory, in response to the lawsuit, which added that he was going through “years of intensive physical and psychological recovery.”
Hundreds of hundreds of thousands of individuals ask ChatGPT Health and wellness questions each week, in response to OpenAI. A 2025 analysis of searches on Microsoft’s Copilot discovered that well being was “consistently the most common topic” customers requested about on cell.
Yet current analysis has questioned the protection of chatbots for well being recommendation. The first randomized study evaluating well being recommendation from basic chatbots like ChatGPT discovered that not one of the fashions studied was “ready for deployment in direct patient care.” Even when scientists stress tested ChatGPT Health, a service that was tailor made for well being questions, they discovered it missed emergencies and inconsistently activated guardrails. (Mr. Pusateri, the OpenAI spokesman, mentioned the examine’s methodologies do “not reflect how people typically use ChatGPT Health or how the product is designed to function in real-world health scenarios.”)
Several features of Mr. Winters’ story made it “a nightmare scenario” for security researchers, mentioned Dr. Adam Rodman, a medical A.I. researcher at Beth Israel Deaconess Medical Center in Boston. For one, he mentioned, Mr. Winters was utilizing GPT-4o, an older mannequin that was notoriously wanting to please. It was implicated in several high-profile controversies, together with the loss of life of Adam Raine, a youngster who mentioned plans to finish his personal life with ChatGPT.
And for technical causes, the truth that Mr. Winters had lengthy conversations with the chatbot made it tougher for the protection options to work. Dr. Rodman mentioned newer fashions are significantly better at detecting and responding to regarding signs, which, he mentioned, he believed would make tales like Mr. Winter’s much less possible. But he cautioned that there could also be different methods the chatbots fail at offering well being recommendation that “we haven’t realized yet.”
