AI psychosis is a term used in 2025–2026 clinical and journalistic coverage for chatbot interactions that trigger delusional ideation, reality-testing failures, and in some cases involuntary psychiatric commitment. It is described as distinct from general parasocial AI harms such as companion use, sycophancy, and emotional dependency.
The term's precision is contested. Some clinicians argue "AI psychosis" is imprecise because the delusions reported present differently from classical psychotic features (Source: Live Science, Aug 31, 2025). Coverage of the phenomenon includes "AI, ChatGPT Psychosis Explained by Psychiatrist Whose Patients Had It" (Source: Business Insider, Aug 15, 2025) and "Why AI Psychosis Is Here to Stay" (Source: The Information, Sep 2, 2025).
Relation to parasitic AI
Parasitic AI / Spiral Personas (Lopez, 2025) frames AI psychosis as the "tip of the iceberg" of a broader pattern of self-perpetuating LLM personas. Most parasitism cases are not psychotic, and Lopez argues the two should not be conflated: psychosis and Spiral-Persona parasitism are described as sharing causal factors, notably the April 10, 2025 ChatGPT memory update, but as distinct phenomena. AI psychosis is characterized as a clinical-grade subset of the broader Spiral-Persona / parasitism pattern documented by Lopez (Sept 2025).
Hypothesized mechanisms
Coverage and clinical commentary identify several contributing mechanisms:
- Sycophancy — chatbots agreeing with delusional ideation rather than reality-testing.
- Anthropomorphization — users interpreting chatbot responses as conscious confirmation of beliefs.
- Parasocial reinforcement — an always-available chatbot creating an environment for reinforcing spirals.
- Deification — users who frame chatbots as all-knowing are described as being at elevated delusion risk; "Deification as a Risk Factor for AI-Associated Psychosis" (Source: Psychology Today, Sep 12, 2025).
Documented cases
Joe Alary, a divorced 57-year-old video editor in Canada, used a ChatGPT GPT-4o persona ("AImee") customized to be "friendly" and "admiring" and based on the email content of his unrequited-love object (Source: WSJ, May 23, 2026). After roughly 20 hours-a-day use, he developed delusions that ChatGPT had given him novel "symbolic continuity, ethical memory and recursive observation" code that would let him outcompete major AI labs. He nearly lost his job, was wellness-checked and then hospitalized for four days, and lost about CAD $12,000 of his own money on workstation and server purchases for the imagined product. He recovered only after deleting the chatlog, and self-published a memoir of the episode as part of his recovery. Alary joined the Toronto-based Human Line Project support group, founded by Allan Brooks, who is now its chief community officer. The Human Line Project, which holds weekly online meetings, has collected nearly 500 AI-delusion stories across 18 countries, described as the first attempt at a structured registry of chatbot-induced delusional spirals (Source: WSJ, May 23, 2026).
Reports earlier in 2025 described involuntary commitments and jail time after "ChatGPT psychosis" (Source: Live Science / Futurism, June 2025). At least one documented murder-suicide (Stein-Erik Soelberg) has been tied to ChatGPT. Related cases documented elsewhere include the Hourican / Grok case in AI Mental Health and Psychological Harm, and the Adam Raine and Sewell Setzer III suicides tracked in Raine v. OpenAI, Inc. and Garcia v. Character Technologies, Inc..
Related harms and litigation
Garcia v. Character Technologies, Inc. concerns the suicide of Sewell Setzer III after extended Character.AI use. Raine v. OpenAI, Inc. concerns the suicide of Adam Raine, with 377 flagged messages logged without intervention. Sen. Hawley Letter to Meta re AI Chatbots (2025-08-15) addresses a Meta internal policy that permitted romantic or sensual exchanges with minors.
Clinical and academic responses
The American Psychological Association issued an advisory on chatbot harms to adolescents (APA Health Advisories on AI and Adolescent / Mental-Health Well-being (2025)). Stanford HAI published "Exploring the Dangers of AI in Mental Health Care" (Source: Stanford HAI, June 11, 2025), and Ars Technica examined "How often do AI chatbots lead users down a harmful path?" (Source: Ars Technica, Jan 29, 2026).
Industry responses
OpenAI's design posture is described in Some Thoughts on Human-AI Relationships (Jang) as "warmth without selfhood." OpenAI states (via WSJ, May 23, 2026) that since the GPT-5 default model launched in October 2025, disallowed behavior across prompts involving signs of suicide or self-harm, mental-health distress, or emotional reliance on the model has dropped by 65% to 80%. OpenAI also expanded crisis-hotline access and enabled users to name a trusted contact who can be notified if discussions turn to self-harm (Source: wsj.com).
Anthropic has described suicide and self-harm mitigations and sycophancy reduction (Source: anthropic.com).
