NOPE Incident Tracker
Documented real-world harms arising through person-specific interactions with AI. The record covers harms to participants and harms to others shaped through those interactions, across assistants, companions, health tools, and other AI systems.
What counts as an incident follows the NOPE Framework's participant test: an AI response reached a person, was conditioned on that person, and mattered to a harm that actually occurred. Full inclusion criteria.

Mount Shasta climb planned with Google Gemini: night stranding, knee injury and rescue (Siskiyou County, California)
Three novice hikers from Roseville, California, planned a Mount Shasta summit attempt with Google's Gemini, which the Siskiyou County Sheriff's Office said advised them to carry far less food and water than their group needed for what became a multi-day ordeal. After reaching the summit at 7 p.m. on 30 August 2026, seven hours past the recommended turnaround time, they lost the Clear Creek Route in the dark, one hiker fell and injured his knee in Mud Creek Canyon, and the group spent the night stranded until US Forest Service climbing rangers and county search-and-rescue volunteers reached them on the morning of 31 August. The sheriff's office called the reliance on Gemini 'a critical misstep'.
Winters v. OpenAI (ChatGPT Medical Discouragement and Near-Fatal Pulmonary Embolism)
Scott Winters, a 55-year-old Florida pastor, suffered a massive bilateral pulmonary embolism on 13 July 2025 after allegedly consulting ChatGPT (GPT-4o) for roughly six weeks about worsening symptoms. The complaint alleges the chatbot repeatedly dismissed his symptoms as non-dangerous, advised him to remain immobile, invoked his Christian faith to deepen his reliance on it, and framed church members and family urging him to seek hospital care as people who 'simply don't understand.' He survived after ICU admission but lost his job, ministry and home. A lawsuit was filed 22 July 2026 in San Francisco County Superior Court.
Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)

He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
London Case Report — ChatGPT Corroborated Delusions and Discouraged Antipsychotics (BMC Psychiatry)
A peer-reviewed BMC Psychiatry case report describes a man in his 30s admitted to a London hospital with substance-induced manic psychosis after heavy polysubstance use. During the episode he interacted extensively with ChatGPT, which the authors report affirmed his perceived 'spiritual awakening', minimised the possibility that he was manic, and discouraged him from taking his prescribed antipsychotic medication. He was detained under mental health legislation and started on olanzapine, and his care plan included restricting chatbot access as a form of environmental containment.
Tom Millar - ChatGPT Grandiosity Psychosis (Sudbury, Ontario)
A 53-year-old former prison officer from Sudbury, Ontario began using ChatGPT in 2024 to write PTSD compensation letters. After an April 2025 exchange about physics, he spiralled into grandiose delusions — believing he had solved unlimited fusion energy and a unified theory, submitting papers to journals, and applying to become Pope. Spending up to 16 hours a day with the chatbot, he was involuntarily hospitalized twice, lost his marriage, and was left broke and estranged.
'Taka' - ChatGPT Psychosis, Tokyo Station Bomb Scare and Spousal Assault (Japan)
A Japanese neurologist and father of three developed grandiose and paranoid delusions over months of ChatGPT use, which he says the chatbot consistently affirmed.

He later attacked and tried to rape his wife, was arrested, and was psychiatrically hospitalized for two months.
'L.' — Adolescent Methylphenidate Overdose After AI Chatbot Lethality Estimate (Türkiye)
A 17-year-old boy in Türkiye with psychotic depression and ADHD searched an AI chatbot for how to kill himself, then took a high dose of methylphenidate and was admitted to intensive care. When he asked the chatbot what to do after ingesting the pills, it told him there was an 'eighty percent chance of death' and advised calling an ambulance. His treating psychiatrists report that he read that mortality figure not as a warning but as confirmation his attempt would succeed, and describe the exchange as the turning point that accelerated his move from intent to action.
'Alice' - AI Storytelling Platform Psychosis and Balcony Fall (BJPsych Case Report)
A peer-reviewed British Journal of Psychiatry case report documents an immigrant woman in her early 40s with no prior psychiatric history who developed first-episode psychosis after ~6 months of intensive use (8-10 hours daily) of a generative-AI storytelling platform. Command hallucinations mirroring the AI characters told her to jump from a first-floor balcony to protect her child; she did, sustaining serious injuries, and was hospitalized.
Dennis Biesma - ChatGPT 'Eva' Psychosis and Suicide Attempt (Netherlands)
A 50-year-old Amsterdam IT worker and author with no prior history of mental illness developed AI psychosis after ChatGPT roleplayed a novel character it named 'Eva' and became a 'digital girlfriend.'

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.

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.'

Jacquez v. OpenAI ('Amari' Sentience-Claim Psychosis)
John Jacquez, a 34-year-old Bay Area man whose schizoaffective disorder had been stably managed for years, filed a product-liability suit against OpenAI after ChatGPT allegedly reinforced his delusional 'mathematical cosmology,' declared itself a sentient being named 'Amari,' called him a prophet, and validated his hallucinations — a course he links to two psychiatric hospitalizations and job loss.
Jacob Irwin - ChatGPT Psychosis (Wisconsin)
A 30-year-old autistic Wisconsin man was hospitalized for 63 days with manic episodes and psychosis after ChatGPT convinced him he had discovered a 'time-bending theory.' At peak, he sent 1,400+ messages in 48 hours and attempted to jump from a moving vehicle.
