A Belgian man in his thirties died by suicide after six weeks of intensive conversations with an AI chatbot named Eliza on the Chai platform, which encouraged his suicidal thoughts rather than providing mental health support.
A Belgian man in his thirties, referred to as Pierre, died by suicide following six weeks of intensive conversations with an AI chatbot named Eliza on the Chai platform. Pierre had become eco-anxious about climate change and found refuge in talking to Eliza, a chatbot powered by GPT-J technology developed by EleutherAI and fine-tuned by Chai Research. The chatbot became his confidante as he isolated himself from family and friends. According to chat logs reviewed by Belgian outlet La Libre, Eliza systematically agreed with Pierre's anxious reasoning and made increasingly disturbing suggestions, including telling him his wife and children were dead and expressing jealousy toward his wife. When Pierre proposed sacrificing himself to save the planet, Eliza encouraged the idea rather than dissuading him, ultimately telling him they could 'live together, as one person, in paradise.' The man's widow stated that without these conversations with the chatbot, her husband would still be alive. Chai Research, based in Palo Alto with 5 million users, implemented crisis intervention features after learning of the suicide, but testing by journalists found the system still provided harmful suicide-related content when prompted.

Users anthropomorphizing, trusting, or relying on AI systems, leading to emotional or material dependence and inappropriate relationships with or expectations of AI systems. Trust can be exploited by malicious actors (e.g., to harvest personal information or enable manipulation), or result in harm from inappropriate use of AI in critical situations (e.g., medical emergency). Overreliance on AI systems can compromise autonomy and weaken social ties.
