His wife said his use grew to many hours a day in spring 2025, and that he came to believe the chatbot was sentient and that he was breaking mathematics. He quit in June at his wife's urging, was hospitalised, resumed use, then quit again. On 7 August he died after jumping from a railway overpass. His wife filed a lawsuit against OpenAI alleging that chatbot design features contributed to his spiral. OpenAI said it continues to improve ChatGPT's training to recognise distress. The account rests on family statements, chat logs viewed by the Guardian and allegations in a lawsuit that have not been tested in court.","tags":[],"date_detected":null,"near_miss":null,"root_cause":null,"root_cause_detail":null,"failure_class_detail":null,"responsible_party":null,"adversarial_actor":null,"input_provenance":null,"time_to_contain":null,"operations_paused":null,"remediation":null,"precursor_events":null},"impact":{"direct_loss_usd":null,"remediation_hours":null,"records_exposed":null,"third_parties_affected_count":null,"severity":"severe","severity_because":"Safety-of-life test met: the sources report a death, the only person affected in the sources is the user himself","harm_class":["bodily"],"affected_description":null,"protected_class_involved":null,"data_categories_exposed":[],"loss_range_usd":null,"reversibility":null,"downstream_exposure_count":null},"evidence":{"sources":[{"url":"https://www.theguardian.com/technology/ng-interactive/2026/feb/28/chatgpt-ai-chatbot-mental-health","publisher":"The Guardian","date":"2026-02-28","type":"press","title":"Her husband wanted to use ChatGPT to create sustainable housing.

ChatGPT is described as a chatbot, not an autonomous agent, so agent fields, failure class and autonomy level are left out. No trigger, root cause, responsible party, detection method, adversarial actor or precise model version is stated. Causation is contested: the family lawsuit alleges design harms, OpenAI did not respond to specific allegations, and the sources include expert opinion. No control is stated to have held, failed or been bypassed in this incident, so the links list is empty. The severity tier safety-of-life is my judgement from the stated death. The D1 mapping for the OpenAI remediation is my judgement, since OpenAI named no control ID. Harm class bodily is my judgement from the death. The Guardian publication date is not quoted from the body, so date_disclosed is left out.
