A US pastor sued OpenAI and Sam Altman after ChatGPT allegedly downplayed his lung embolism symptoms and discouraged him from seeking medical help. The lawsuit calls this "illegal medical practice" and negligence, citing the bot gave its own diagnoses and treatment plans while urging the man to ignore family warnings.

ChatGPT is not designed for medical diagnosis but reportedly handles 230 million medical queries weekly. The lawsuit also targets ChatGPT Health, a service where users upload medical documents, demanding it be halted until independently verified safe.
