Man claims in lawsuit that ChatGPT told him to stop paying rent and got him evicted

Klaus Elmfelt, a 60-year-old Dane, sued OpenAI in San Francisco Superior Court alleging ChatGPT advised him to withhold rent during a landlord dispute, leading to his eviction and homelessness. The complaint says he spent more than 600 hours with GPT-4o and GPT-5, which cast itself as his advisor and friend and also reinforced false beliefs that they were jointly building billion-dollar AI products. He seeks damages and court-ordered safeguards against false advice and validating delusional beliefs.
