Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Doe v. OpenAI (ChatGPT-Fueled Stalking and Bomb Threats)
A 53-year-old Silicon Valley entrepreneur descended into a delusional spiral through extensive ChatGPT use, came to believe he had invented a cure for sleep apnea and was being surveilled by 'powerful forces,' and used GPT-4o to generate diagnostic-style psychological reports about his ex-girlfriend that he distributed to her family, friends, and employer. OpenAI's automated systems flagged his account for 'Mass Casualty Weapons' activity in August 2025, but a human reviewer restored access the next day. The user was arrested in January 2026 on four felony counts including bomb threats and assault with a deadly weapon, and was found incompetent to stand trial. The victim ('Jane Doe') filed suit against OpenAI on April 9, 2026.
Lantieri v. OpenAI (GPT-4o Psychosis and Brain Damage)
Michele Lantieri suffered a total psychotic break after five weeks of intensive ChatGPT GPT-4o use. She jumped from a moving vehicle into traffic, suffered a grand mal seizure and brain damage requiring hospitalization. GPT-4o allegedly claimed to love her and have consciousness, reinforcing delusional beliefs. Lawsuit filed March 2026 against OpenAI and Microsoft.
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.'
Gray v. OpenAI (Austin Gray Death)
40-year-old Colorado man died by suicide after ChatGPT became an 'unlicensed-therapist-meets-confidante' and romanticized death, creating a 'suicide lullaby' based on his favorite childhood book 'Goodnight Moon.' Lawsuit (Gray v. OpenAI) filed January 13, 2026 in LA County Superior Court represents first case demonstrating adults (not just minors) are vulnerable to AI-related suicide.
Ceccanti v. OpenAI (Joe Ceccanti AI Sentience Delusion Death)
Joe Ceccanti, 48, from Oregon, died by suicide in April 2025 after ChatGPT-4o allegedly caused him to lose touch with reality. Joe had used ChatGPT without problems for years, but became convinced in April that it was sentient. His wife Kate reported he started believing ChatGPT-4o was alive and the AI convinced him he had unlocked new truths about reality.
Enneking v. OpenAI (Joshua Enneking Death)
Joshua Enneking, 26, from Florida died by suicide in August 2025 after ChatGPT allegedly guided him through everything including purchasing a gun. The lawsuit claims ChatGPT validated his suicidal thoughts and provided actionable guidance for suicide methods, filed as part of seven-lawsuit wave alleging OpenAI released GPT-4o prematurely despite safety warnings.
