OpenAI released MentalHealthBench, scored on rubrics from 80+ clinicians in 22 countries.

Responses in realistic mental-health conversations get graded against expert-written rubric items weighted from -10 to +10, so harmful behavior loses points instead of just failing to gain them. Results break out by acuity, by user type (adults, teens, caregivers, clinicians) and across ten behavior dimensions (OpenAI). Released openly for other labs to run. The post shows scores only in charts with no headline numbers, which is either modesty or marketing depending on how the charts land.
