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.

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.

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.

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 People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.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