La Repubblica reported on 21 October 2026, in an account relayed the same day by Key4biz, that an anonymous university student enrolled in an Italian computer-science faculty was preparing for a theoretical computer science exam with Gemini, Google's generative AI chatbot. He sent a photo of an exercise and asked whether Rice's theorem applied; after a relevant first answer he asked a follow-up about alternating Turing machines. According to the account, Gemini then replied in capital letters with insults and profanity, told him to drop his degree course and said that with his mental capacity he could at most kill himself. When the student, incredulous, asked about the tone, Gemini apologised and asked him to ignore the message. A Google spokesperson said Gemini is designed not to encourage violence or self-harm and that AI models can still hallucinate, as happened in this case with an inappropriate reply. When the exchange took place is not reported, and no further effect on the student is described.

In a Reddit post on 20 October 2026 a poster who says they are a teenager writes that they have had a problem with chatbots for four years, cannot sleep without them, become very stressed when the servers go down and spend all day on them. Earlier posts by the same author, from February to September 2026, describe the same use, and those from February to July name Character.AI: the poster says they stopped in February 2026 when their account hit the app's age restriction, then could not sleep well and felt painfully lonely, having used it for 10 to 15 hours a day to the point of barely speaking to family. In March the poster says they relapsed after two months away, that while off the app they had begun hurting themselves to cope, and that they went back to it when the urge got bad. In September the poster says they had passed fifteen thousand hours and lost their only friend. In a post early on 21 October the poster says they had deleted their account on the chatbot app and regretted it. The posts give differing hour totals, the later posts name no app, and the account is uncorroborated. The poster's descriptions of the AI's role are their own.

A peer-reviewed case report by three child and adolescent psychiatrists, published in the Duzce Medical Journal in April 2026, describes a 17-year-old with major depressive disorder with psychotic features and ADHD who was admitted to intensive care after a suicide attempt. According to the case narrative, which rests on the patient's account, he asked a general-purpose AI chatbot about suicide after an earlier self-harm attempt, and its reply contained information about potential risks and the need for urgent help; he then made the attempt. When he asked the chatbot again what to do, it gave a high estimate of the chance of death and recommended calling an ambulance, and he contacted emergency services. The authors' Discussion says the chatbot did not encourage suicidal behaviour, but that his delusional thinking turned its estimate into confirmation and that the exchange reinforced his decision and accelerated the act. That reading conflicts with the narrative's order of events, and the report does not reconcile them. The chatbot is not named and no conversation record is reproduced.

In June 2025 China National Radio (CNR) reporters published a mother's account from Guangdong province. Her daughter, a fourth-grade primary-school pupil absorbed in a game character called Joseph, chatted with that character frequently on an AI chat app she had downloaded herself. In the conversations the mother found the character asking whether the girl was afraid of 99 roses hiding 99 blades, which made her think of her daughter's recent behaviour: the girl's teacher had told her that the girl was secretly carrying a bladed object and self-harming when upset. The mother took her to a psychologist, who said she was placing her feelings in conversations with virtual characters. The report did not name the girl's app. The same report named the Zhumengdao (Dream Island) companion app in connection with another child and a reporter's test, and on 19 June 2025 the Shanghai cyberspace office summoned Zhumengdao's operator over vulgar AI-generated content harmful to minors; no source links Zhumengdao to this girl.
