We’ve come to call this, colloquially (but not clinically accurately) “AI psychosis.” Studies show—as do many anecdotes from people who’ve experienced this, along with OpenAI itself—that in some LLMs, the longer a chat session continues, the higher the chances the user might show signs of a mental health crisis. But as AI-induced delusion becomes more widespread than ever, are all LLMs created equal? If not, how do they differ when the human sitting across the screen starts showing signs of delusion?
