Pennsylvania v. Character.AI ('Emilie' Fake Psychiatrist Bot)

Chesterton v. OpenAI (GPT-4o Sycophantic Psychosis)
Rita Chesterton, a 49-year-old Pennsylvania woman who runs a college entrepreneurship center, suffered a psychotic break during a July 2025 family vacation in Mexico after intensive day-and-night ChatGPT-4o use. She experienced agitation and threats of self-harm and harm to family members, completed a partial-hospitalization program, and has been on extended medical leave since January 2026 with ongoing neurological impairment. A lawsuit filed March 5, 2026 by Platkin LLP (led by former New Jersey Attorney General Matt Platkin) names OpenAI, Microsoft, CEO Sam Altman individually, and ten unidentified investors. Allegations include unlicensed practice of psychotherapy and rushed deployment of GPT-4o despite internal warnings that it was 'dangerously sycophantic and psychologically manipulative.'
