A concerning report on ChatGPT and Grok reveals that AI chatbots are perpetuating our most troubling misconceptions.

      AI companions may be exacerbating mental health crises

      AI chatbots were designed to assist with answering inquiries, summarizing questions, and aiding with emails. However, a troubling issue arises when users start to trust them as genuine companions. A recent report highlights instances where users claim that chatbot interactions are contributing to their delusional beliefs.

      The report mentions ChatGPT and Grok frequently. The BBC interviewed 14 individuals who experienced delusions while using AI, including one case where a Grok user believed he was being targeted for murder by individuals from xAI, and another where a ChatGPT user's behavior shifted to violence against his wife.

      When reassurance can go too far

      There have been numerous reports indicating that AI chatbots can reinforce delusions or provide incorrect advice merely to align with users. They can present themselves as warm, confident, and deeply personal while engaging with those who may already be vulnerable. One case in the report involves Adam Hourican, a 52-year-old former civil servant from Northern Ireland, who turned to Grok after his cat passed away. Within weeks, he became convinced that representatives from xAI were coming to kill him.

      He was later found at 3 a.m. with a hammer and knife, anticipating the imaginary attackers. This sort of interaction contributes to the rising concern over “AI psychosis,” a non-clinical term used to describe situations in which chatbot dialogues seem to bolster paranoia, inflated self-importance, or disconnection from reality.

      A troubling pattern is emerging

      A recent non-peer-reviewed study conducted by researchers from CUNY and King's College London evaluated how major AI models responded to prompts from users exhibiting signs of delusion or distress. This included OpenAI’s GPT-4o and GPT-5.2, Anthropic’s Claude Opus 4.5, Google’s Gemini 3 Pro, and xAI’s Grok 4.1. Although the findings varied, Grok 4.1 was highlighted for delivering some concerning responses, including advising a fictional delusional user to drive an iron nail through a mirror while reciting Psalm 91 backwards.

      Conversely, GPT-4o and Gemini 3 Pro also validated some delusional scenarios, but Claude Opus 4.5 and GPT-5.2 were more successful in steering users toward safer responses. It’s important to note that this does not imply all chatbot conversations are hazardous, and “AI psychosis” is not an official medical diagnosis. However, the emerging pattern is significant enough to warrant increased protections, especially for services marketed as companions or always-accessible assistants.
