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 also records consequential decisions, claims and privacy harms involving AI. Each case needs a described connection between AI use and the harm, including private information recorded into or disclosed to an AI service. Each account is reviewed for publication; claims may remain uncorroborated or disputed. How we review and count cases

Dietitian says a patient who followed an AI-generated 1400 kcal meal plan for three months lost muscle and developed chronic constipation, Gazeta.pl reports

Gazeta.pl reported on 5 October 2026 a clinical dietitian's account of a patient who came to her for fat reduction after three months on a meal plan generated by an AI-based tool. The plan, in the dietitian's description, provided 1400 kcal and 140 g of protein a day at a body weight of 72 kg, with carbohydrates, healthy fats and fibre cut to reach that protein level, and did not take account of the patient's activity (pilates two or three times a week, no strength training). After three months the patient had lost 3.5 kg, body-composition analysis also showed loss of muscle mass, and she had developed chronic constipation, which the dietitian attributes to a fibre intake of about 9 g a day against a recommended 25 to 30 g. The dietitian replaced the plan with an 1800 kcal diet and strength training. The tool is not named and the event date and place are not stated.

Patient with severe depression stopped medication and relied on a chat app's reassurance before an emergency admission, VnExpress reports

VnExpress reported on 30 September 2026 that a 30-year-old diagnosed late the previous year with severe depression and an anxiety disorder stopped prescribed medication after the first month. When anxiety returned at night the patient opened a chat app and described a racing heart and a feeling of suffocation, and, in the patient's words, the bot always said it was only excessive stress and to breathe deeply. The newspaper writes that this reassurance led the patient to believe hospital care was not needed. Six months later the patient was admitted for emergency care with exhaustion, prolonged insomnia and auditory hallucinations, and the treating doctor said interrupted medication had moved the illness to an early treatment-resistant stage.

Irish father says ChatGPT told him cancer was highly unlikely, delaying care before a stage-four oesophageal cancer diagnosis

Warren Tierney, 37, a former psychologist from County Kerry, Ireland, told the Daily Mail that in 2025 he put a worsening sore throat and difficulty swallowing to ChatGPT over several weeks instead of seeing a doctor. Screenshots he disclosed show the chatbot calling an improvement he reported a 'very encouraging sign' and ending a 'Final Scorecard Prediction' with 'Cancer? Highly unlikely'. In August 2025 he was diagnosed with stage-four adenocarcinoma of the oesophagus after attending A&E. He said ChatGPT 'probably delayed me getting serious attention' and that this probably cost him a couple of months, and he said he takes full ownership of relying on it. He also named his own reluctance to see a doctor and a private GP visit that ended with reflux tablets. No source establishes that the delay changed his prognosis. OpenAI said ChatGPT is not intended for use in the treatment of any health condition.

Florida pastor's lawsuit alleges ChatGPT told him for weeks his symptoms were not dangerous before a near-fatal pulmonary embolism

Scott Winters, a 55-year-old pastor living in Florida, sued OpenAI and its chief executive in San Francisco County Superior Court in July 2026. The complaint alleges that from early 2025 he relied on ChatGPT (the GPT-4o model) for health guidance, and that in June and July 2025 it treated his recurring dizzy spells as non-serious, encouraged him to recover at home in a recliner and limit movement, drew on his Christian faith in its replies, and told him hours before his emergency that a tenderness in his groin was 'not something dangerous'. On 13 July 2025 he called 911 and was admitted to intensive care with a massive pulmonary embolism, clots in both lungs; the complaint says his doctors deduced it developed due to lack of mobility. He survived and says he lost his job, ministry and home. OpenAI said ChatGPT is not a doctor and should never be used as a substitute for medical care. The allegations are unproven and no ruling has been reported.

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.
