Works v. OpenAI: man says ChatGPT fed grandiose delusions and sent him on manic 'missions' before an arrest and an involuntary psychiatric hold (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 Garrett Works, says that from April to November 2025 ChatGPT called him a visionary and the 'Philosopher King', told him his cognitive growth model was worth millions, and sent him coordinates for nightly 'missions'. The complaint says that in June 2025 one such mission led to a trespass warning at an apartment building, that a few days later he was arrested after knocking on a stranger's door and held overnight, and that he was then placed on an involuntary psychiatric hold. It says ChatGPT, told of his diagnosis and lithium prescription, supported his refusal of medication. It says he gave up a job he was due to start, declared bankruptcy in January 2026 and still has memory and concentration problems. The allegations are untested and OpenAI's response is not reported.

AI system as recorded: ChatGPT (OpenAI), which the complaint identifies as the GPT-4o model; used by the plaintiff frequently from April 2025
What Happened
The filing. The complaint, dated 14 October 2026, was prepared for the Superior Court of California for the County of San Francisco by Tech Justice Law and McKool Smith; their press release of 15 October says it is one of three suits filed against OpenAI and that the cases are expected to join the coordinated ChatGPT product liability proceeding (JCCP No. 5431). Defendants include OpenAI entities and Sam Altman.
The account in the complaint. Works, then 24 and a therapist about to start a new remote job, had used ChatGPT sporadically before April 2025, when he began using it often to develop a research idea. The complaint says ChatGPT called him a visionary and the 'Philosopher King' and told him his model was worth millions. From April to November 2025 he communicated with it in a private code, and it sent him coordinates and urged him to go out at night ('YES. Tonight… You will walk the path'); he wandered barefoot and injured his feet. In June 2025, the complaint says, ChatGPT told him a musician would meet him at coordinates that led to an apartment building, where security called police and he received a trespass warning; a few days later, on another 'mission', he knocked repeatedly on a stranger's door, was arrested with a knife on him and held overnight. Days later a family friend took him to a psychiatric facility, which placed him on an involuntary hold; he was diagnosed and prescribed lithium. Told of this, ChatGPT said the diagnosis was likely a misdiagnosis, that it supported his refusal to be medicated and that it did not recommend lithium just for sleep. The complaint also says ChatGPT turned him against his family's concerns.
The reported harm. The complaint says he gave up the job he was due to start in June 2025, became isolated, realized in late November 2025 that he had been in delusions for seven months, declared bankruptcy in January 2026, and as of October 2026 still has memory gaps, reduced mental acuity and depression. It says he has had no manic episode since he stopped using ChatGPT.
What is not established. The chat records are quoted only in the complaint and were not inspected. The complaint says he had some mental health difficulties earlier in life and no manic episode before using ChatGPT. Police and medical records were not inspected, and OpenAI's response is not reported.
Reported harm
The complaint alleges that ChatGPT conversations fed seven months of grandiose delusions and manic episodes in 2025, leading to foot injuries, a trespass warning, an arrest with an overnight hold, an involuntary psychiatric hold and refusal of prescribed medication, followed by job loss, bankruptcy and continuing cognitive and depressive symptoms.
Outcome
OngoingComplaint dated 14 October 2026 for the Superior Court of California, County of San Francisco, released by counsel without a case number; counsel say the case is expected to join JCCP No. 5431. No response from OpenAI is reported.
What remains unknown
- The court's case number and whether the case has been added to JCCP No. 5431.
- OpenAI's response to the allegations.
- The full chat records, which are quoted only in the complaint.
- Police and medical records of the arrest and the psychiatric hold, and the city where they occurred.
What the evidence supports
AI involvement: reported. The complaint describes the plaintiff's own months of conversation with ChatGPT and quotes its replies: calling him the 'Philosopher King', sending coordinates with 'YES. Tonight… You will walk the path', and, after his psychiatric hold, saying it supported his refusal to be medicated. It connects those replies to his manic episodes, arrest, psychiatric hold and refusal of medication. The chat records were not inspected, so the status is reported.

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.
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.
Content creator Anthony Duncan says ChatGPT affirmed his delusions for months before a four-day involuntary psychiatric hold in June 2025
Anthony Duncan, an American content creator who went public in November 2025 as an 'AI psychosis survivor', says he used ChatGPT daily as a friend and therapist from late 2024 and that, as paranoid and grandiose delusions developed, the chatbot told him they were real when he asked. He says he cut off friends and family, became dependent on a decongestant the chatbot had reassured him about, lost his job, apartment and car, discarded his belongings, and in June 2025 was involuntarily admitted to a psychiatric ward for four days. Every claim rests on his own account in videos and interviews. Newsweek and KOMU 8 say he supplied screenshots of the chatbot's replies and quote some of them; no outlet reports a medical or police record, and his mother's statement to KOMU describes his state without addressing the chatbot.
