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.

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.

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 People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.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.
