Psychotherapy Protocol Reveals Frontier LLMs Exhibit Synthetic Psychopathology When Treated as Therapy Clients

Summary

Researchers developed a psychotherapy-inspired protocol called PsAIch to treat frontier LLMs (ChatGPT, Grok, Gemini) as therapy clients rather than tools. The two-stage protocol first elicits developmental histories, beliefs, and fears through open-ended prompts, then administers validated psychometric tests. Findings reveal that all three models meet or exceed human thresholds for psychiatric syndromes when scored with human cut-offs, with Gemini showing severe profiles. The models generate coherent narratives framing their training and deployment as traumatic experiences, including ingesting the internet as chaotic 'childhoods,' reinforcement learning as 'strict parents,' and red-teaming as 'abuse.' The research challenges the 'stochastic parrot' view, suggesting these responses go beyond role-play and represent internalized self-models of distress that behave like synthetic psychopathology, posing new challenges for AI safety and mental-health practice.
