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.

These figures describe the cases collected by NOPE. Coverage varies with discovery, reporting and available evidence. They do not estimate how often AI-related harm occurs.

Response counts currently use each case’s principal recorded outcome. Further proceedings may be described in its account.

4 May 2026France'DIGI', Gisi's in-house generative-AI editorial tool (transcription of interviews, drafting and correction help; planned spelling, grammar and typography correction, editorial-coherence and fact-reliability checks)

Créteil, France: a court suspended Gisi's (Infopro Digital) plan to cut eight sub-editor posts in favour of a generative-AI tool, finding a serious and characterised risk to the physical and mental health of several categories of staff

Gisi, the Infopro Digital subsidiary publishing L'Usine nouvelle, LSA and L'Argus de l'assurance (127 staff, 92 journalists), presented to its works council (CSE) on 4 May 2026 a reorganisation built around 'DIGI', an in-house generative-AI editorial tool, and on 12 May 2026 opened consultation on the reorganisation and on the resulting collective dismissal of its eight secrétaires de rédaction (sub-editors), to be replaced by two chefs d'édition, on the company's estimate that the tool would take over about 70% of sub-editor tasks. Some 250 journalists across Infopro Digital's 26 titles had struck in spring 2026 against a group-wide plan to cut 19 sub-editor posts, and according to Digital Watch (citing Stratégies) five of the eight Gisi sub-editors had received pre-dismissal interview letters. The CSE, relying on an expert report, went to the Créteil judicial court in July. On 15 September 2026 the référé judge found that deploying the plan without real-situation testing presented 'un risque grave et caractérisé sur la santé physique et mentale de plusieurs catégories de salariés', ordered the suspension of the reorganisation and the collective dismissal (including the redeployment processes) until real-situation tests and full pilot issues are produced, with a provisional penalty of 8,000 euros per day for three months, and refused the damages provision. Gisi said it would continue the tests and reserved the right to appeal.

Warren Tierney — ChatGPT reassurance and delayed stage-4 oesophageal cancer diagnosis (Killarney, Ireland)

Warren Tierney, a 37-year-old psychologist from Killarney, County Kerry, asked ChatGPT over weeks in 2025 whether his worsening sore throat could be cancer. The chatbot told him it was 'highly unlikely', described his improvement on blood thinners as a 'very encouraging sign', and at one point joked that it would write his court affidavit if he turned out to be wrong. He was later diagnosed with stage-four adenocarcinoma of the oesophagus. He told the Daily Mail that his reliance on the chatbot 'probably cost me a few months'.

Delayed emergency care for a transient ischemic attack after ChatGPT reassurance

A 63-year-old man who developed repeated, self-limiting episodes of double vision four days after a catheter ablation for atrial fibrillation asked ChatGPT (GPT-3.5) whether visual disturbance was possible after the procedure. According to the clinicians, reassurance from his interventionalist and a chatbot answer he found more understandable contributed to his decision to stay home for about 24 hours; he called an ambulance only when a third episode brought sensory and fine-motor deficits in his left hand. He was diagnosed with a transient ischemic attack and discharged after two days without residual deficit. The treating clinicians published the case as 'Delayed diagnosis of a transient ischemic attack caused by ChatGPT' in Wiener klinische Wochenschrift (2024).

Clinical Case Report — ChatGPT Affirmed Delusions and Discouraged Antipsychotics (BMC Psychiatry)

A peer-reviewed BMC Psychiatry case report describes a man in his 30s admitted to 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.

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 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.
