OpenAI LLC is a California product-liability and consumer-protection case brought in San Francisco Superior Court by Florida pastor Scott Winters and reported in July 2026 against OpenAI and its chief executive, Sam Altman.

Reviewed complaint court-stamped August 3, 2026; subsequent docket developments not verified.^[2]^[1]

Background

Winters alleges that he consulted ChatGPT-4o about recurrent dizziness and other symptoms over approximately six weeks and that the chatbot characterized the symptoms as non-dangerous rather than directing him to urgent medical care.^[3]^[4] He alleges that the chatbot drew on his religious identity and discounted concerns raised by family and church members, contributing to delayed treatment for a pulmonary embolism.^[3]^[4]

Claims and Requested Relief

The complaint asserts strict-liability, negligence, unfair-competition, invasion-of-privacy, and negligent-undertaking claims.^[3] Winters seeks damages and injunctive relief, including stronger medical-safety guardrails and a pause in ChatGPT Health until independent reviewers determine it is safe.^[3]^[4]
