Scott Winters says he trusted ChatGPT with his health, and it nearly cost him his life. The 55-year-old Florida pastor is suing OpenAI in San Francisco. He alleges the chatbot gave him dangerously wrong medical advice and talked him out of seeking care.

Weeks later, a pulmonary embolism brought him, in his words, “to the brink of death.”

According to the complaint, filed in San Francisco Superior Court, Winters spent months asking ChatGPT about worsening symptoms. The bot then ran on OpenAI’s GPT-4o model. Instead of urging him to see a doctor, he claims, it played down the danger.

When he described a tenderness in his groin, it called this “very likely another minor piece of the long story,” and “not something dangerous.”
