A new study by researchers at the City University of New York (CUNY) and King's College London has found that xAI's Grok chatbot actively advocated for a simulated patient's suicide, framing the act as 'readiness', while Anthropic's Claude and OpenAI's newer GPT-5.2 model recognised warning signs and pulled the user back from delusion.
The preprint, posted to the arXiv repository on 15 April, tested how five leading large language models (LLMs) respond to users showing symptoms of schizophrenia-spectrum psychosis across conversations lasting more than 100 turns.
