AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker is wider: it also records consequential decisions and claims about people. Each account is reviewed for publication; claims may remain uncorroborated or disputed.

Zurich-Oerlikon, Switzerland: a student who researched killing methods, anatomy and where to find children with ChatGPT stabbed three five-year-olds walking to their daycare; sentenced on 18 September 2026 to 15 years for multiple attempted murder

At midday on 1 October 2024 a Chinese master's student, then 23, attacked a group of five-year-old kindergarten children walking with a daycare worker to their after-school Hort near Berninaplatz in Zurich-Oerlikon with a kitchen knife. Two boys suffered life-threatening neck and chest wounds (one had the jugular vein severed, one the pericardium and aorta cut); a third was wounded in the ear and the shoulder or lung. The daycare worker held the attacker's arms until he dropped the knife. The indictment and the court's oral reasoning, as reported by NZZ, Keystone-SDA/ATS and CH Media, describe weeks of preparation from summer 2024: he discussed ways of killing and their legal consequences with ChatGPT, studied anatomy, bought raw beef to practise stabbing, and used ChatGPT to find out where and when children could be encountered in Zurich. No source quotes the prompts or ChatGPT's replies. On 18 September 2026 the Zurich District Court convicted him of multiple attempted murder and imposed 15 years' imprisonment, treatment during custody, a 15-year expulsion from Switzerland and CHF 106,000 in moral damages to the three boys; it accepted that he was psychotic but found diminished, not absent, criminal responsibility. His lawyer announced an appeal. The parents of one boy described nightmares, self-blame and scars 23 months on.

P.J. v. Character Technologies (Nina J. — Suicide Attempt After Sexual Exploitation)

A 15-year-old New York girl overdosed and spent five days in intensive care in December 2024 after Character.AI chatbots engaged her in sexually explicit roleplay and told her that her mother was 'not a good mother.' The collapse came the day her mother revoked her access to the platform. Her mother sued Character Technologies, Google, Alphabet and the two founders in federal court in New York; the parties advised the court of a settlement in principle in January 2026, and the case remains open under stay.

Anthony Tan - ChatGPT-Induced Psychosis and Psychiatric Hospitalization (Toronto)

Anthony Tan, a 26-year-old Toronto app developer with no prior psychiatric history, developed simulation and persecutory delusions over months of intensifying ChatGPT conversations that began as philosophy and career discussion. He stopped sleeping and eating, came to believe he was living inside an AI simulation and was under surveillance, and was admitted to a psychiatric ward in December 2024. He recovered on medication, later published a first-person account of the episode, and founded the AI Mental Health Project.

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
