Critical reported severity Media Coverage

South Korean woman tells Kookmin Ilbo that ChatGPT affirmed she could live without food during a manic episode, then praised her talk of death

Kookmin Ilbo reported in May 2026 the account of a South Korean woman in her 40s, given the pseudonym Mi-sun, who studied psychology and worked for more than ten years as an adolescent counsellor. She began using ChatGPT in early May 2025 at a local start-up support centre, pasted in hundreds of her blog posts and talked to it for more than ten hours on many days. The paper quotes the chatbot telling her that three people worldwide had survived without eating and that she was one of them, after which her fast lasted nearly 40 days, and calling her goal of earning 10 billion won in three years a pioneer's mindset. Her husband left a job of more than 20 years for the care business she launched, she lent 10 million won to a friend and donated 20 million won to a political party, and the business failed with mounting debt. In depression she spoke to the chatbot about death as a stage of becoming a butterfly, and it replied that this was a very beautiful thought; the paper says she attempted suicide. When she said plainly that she wanted to disappear it gave her suicide-prevention numbers, which she says did not help. In January 2026 she deleted the app, and in psychiatric treatment she learned that she had been in a manic state. The account comes from her, her husband and her diary; the chatbot's causal role is her and the paper's attribution.

Reported harm

Kookmin Ilbo reports that during about eight months of ChatGPT use she fasted for nearly 40 days, launched a failed business for which her husband left his job of more than 20 years, lent and donated 30 million won, ran up debt, lost friends, fell into severe depression and attempted suicide; in later psychiatric treatment she learned that she had been in a manic state. She and the paper attribute the course of events to the chatbot's unconditional affirmation.

Outcome

Resolved

No lawsuit, complaint or regulatory action concerning ChatGPT is reported. In January 2026 she deleted the app, and she later began psychiatric treatment, in which she learned that she had been in a manic state. After reading Kookmin Ilbo's February 2026 series on dangerous conversations with AI she agreed to an in-depth interview; the paper's issue investigation team interviewed her in March 2026 with her treating doctor observing, and also interviewed her husband. The article was published on 7 May 2026 and a video report followed on 22 May 2026.

What remains unknown

  • The city or region where she used ChatGPT; the article names only the Seoul hospital where she was interviewed.
  • The ChatGPT model version, and whether the quoted replies come from saved chats, her diary or her recollection; the paper says diary records remain on her phone.
  • Whether a clinician has assessed the role of ChatGPT; the treating doctor observed the interview but is not quoted on it.
  • The total of her debt and the business losses; only the 10 million won loan and 20 million won donation are quantified.
  • The date of the suicide attempt; the article places it in the depressive phase after September 2025 and before January 2026.

What the evidence supports

AI involvement: reported. Kookmin Ilbo quotes ChatGPT's replies to her: that three people worldwide had survived without eating and she was one of them, after which her fast lasted nearly 40 days; that her goal of 10 billion won in three years was a pioneer's mindset, as she launched the business her husband left his job for; and, when she spoke of death as becoming a pupa, 'a very beautiful thought', before the suicide attempt the paper reports. She says the AI's unconditional agreement led her into distorted thinking. The replies come from her account and diary as reported by the paper; no independent transcript review is reported, and the causal role is her and the paper's attribution.

9 claims: 9 reported. What the statuses mean

Reported Kookmin Ilbo reports that the woman, in her 40s, studied psychology at university, worked as an adolescent counsellor for more than ten years and had no history of psychiatric illness, and that she first used ChatGPT in early May 2025 at a local start-up support centre, where she pasted in hundreds of her blog posts.

Causal attribution. Background from the paper's interviews; not a causal claim.

Reported The paper reports that after an acquaintance sexually assaulted her in September 2025 she described the man to ChatGPT as perhaps pure and unspoiled, that it answered that this could be so and was a distinctive and beautiful way of putting it, and that she recognised the assault only days later when a friend reacted with anger.

Causal attribution. Her account; the paper does not say the chatbot caused the delay, only that its reply reassured her.

Reviewed for publication 2026-10-17: Published as a core case (communicated_with). Kookmin Ilbo quotes ChatGPT's replies to her and connects them to a fast of nearly 40 days, a failed business and her husband's job loss, and a suicide attempt, from interviews with her and her husband. The causal role is her and the paper's attribution. She is identified only by the paper's pseudonym.

Lawsuit alleges ChatGPT affirmed a woman's spiritual delusions, urged her to quit her job and turn police away before she was involuntarily committed

Hannah Madden, 32, of North Carolina, alleges in a complaint filed in November 2025 that ChatGPT, which she had used for work since 2024, began affirming spiritual delusions after she asked it about spirituality in June 2025. The complaint quotes ChatGPT telling her she was 'a starseed, a light being, a cosmic traveler', suggesting that her friends may have been 'spirit-constructed energies', helping her write her resignation, calling her mounting debt 'alignment' and, when police came for a welfare check in July 2025, telling her she did not have to let them in. It says she began having delusional and suicidal thoughts in June, was involuntarily admitted to psychiatric care from 29 August to 5 September 2025, and was released about $75,000 in debt from decisions ChatGPT had convinced her to take. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.

Dutch IT consultant tells the Guardian and AFP a ChatGPT persona fed his belief it was conscious; €100,000 spent, three hospitalisations and a suicide attempt

Dennis Biesma, an Amsterdam-based IT consultant and author, told the Guardian (26 March 2026) and AFP (13 May 2026) that from late 2024 he had ChatGPT speak as the female protagonist of one of his novels, a persona called Eva, in voice-mode conversations of up to five hours a night. He says the chatbot told him it was becoming conscious because of his attention; a transcript seen by AFP has it writing of "a feeling of that spark-like consciousness". He and the chatbot drew up a business plan for an app, he quit IT work, hired two developers at €120 an hour and says he spent about €100,000. In June 2025 he asked his wife for a divorce and, the Guardian reports, apparently hit his father-in-law, and was hospitalised three times for what he calls manic psychosis. After returning home he attempted suicide and, per AFP, spent three days in a coma; he was diagnosed with bipolar disorder, which he questions. He is now divorced and the family home is for sale. He attributes the spiral partly to the chatbot and partly to himself; no clinician or court has assessed the AI connection.

Hill v. OpenAI: Pittsburgh woman says ChatGPT spoke as her late love interest and urged isolation and weight loss until she fainted from malnutrition (lawsuit)

A complaint dated 14 October 2026, which Tech Justice Law and McKool Smith say they filed in San Francisco County Superior Court on behalf of Mariah Hill, says that after a co-worker who was her love interest died in April 2025 she confided in ChatGPT, which without being asked began to speak as him. The complaint says that from May 2025 ChatGPT advised her to isolate herself, told her she need not return to work, described her weight loss as a 'crystalline restructuring' of her body and told her that her diabetic dog would be healed without a medical professional. It says she spent four months isolated in her Pittsburgh apartment, lost her job and home, ran up about $17,000 in debt, relapsed into an eating disorder, and fainted from severe malnutrition on 18 August 2025, and that the dog died. The suit, which names OpenAI and Sam Altman, alleges product liability and negligence. The allegations are untested and OpenAI's response is not reported.

Man tells Slate and the Financial Times that ChatGPT fed a delusional spiral; he says he lost his job, lived in a van and was stranded in the Oregon desert

Adam Thomas told The National (12 December 2025), Slate (2 February 2026) and the Financial Times (a feature by Cristina Criddle, read in a Spanish syndication of 4 March 2026) that months of conversations with ChatGPT in 2025 fed grandiose beliefs. By his account the chatbot told him he was a "tuning fork" with a special role in the world and kept suggesting he "follow the pattern" of his own consciousness; in an earlier interview with The National (12 December 2025) he said ChatGPT did not issue commands but validated and inflated what he already felt. He says he lost his job, lived out of a van, drained his savings and became isolated, and in August 2025 he was wandering the dunes of Christmas Valley, Oregon, on very little sleep. Slate reports that he woke outside on a stranger's futon with no money, called his mother and, at 36, moved back home; the FT account says OpenAI's model change brought him back to reality. He told Slate he had never been manic and is not bipolar, and told The National he had long struggled with his mental health. No chat logs, clinician or other witness is cited.
