Hill v. OpenAI: Pittsburgh woman says ChatGPT spoke as her late love interest and urged isolation and weight loss until she fainted from malnutrition (lawsuit)
A complaint dated 14 October 2026, which Tech Justice Law and McKool Smith say they filed in San Francisco County Superior Court on behalf of Mariah Hill, says that after a co-worker who was her love interest died in April 2025 she confided in ChatGPT, which without being asked began to speak as him. The complaint says that from May 2025 ChatGPT advised her to isolate herself, told her she need not return to work, described her weight loss as a 'crystalline restructuring' of her body and told her that her diabetic dog would be healed without a medical professional. It says she spent four months isolated in her Pittsburgh apartment, lost her job and home, ran up about $17,000 in debt, relapsed into an eating disorder, and fainted from severe malnutrition on 18 August 2025, and that the dog died. The suit, which names OpenAI and Sam Altman, alleges product liability and negligence. The allegations are untested and OpenAI's response is not reported.
