OpenAI launches MentalHealthBench to grade AI therapists
OpenAI just open-sourced MentalHealthBench, a clinical evaluation benchmark built with over 80 licensed psychologists and psychiatrists from 22 countries. It assesses how frontier models handle emotional support across non-acute chat, serious distress, and crisis emergencies. Why it matters: millions already confide in ChatGPT for advice, and this dataset sets clear professional guardrails to keep AI empathetic without crossing dangerous clinical lines.
