It’s pretty hard to systematically compare the behaviors of AI systems, especially over multi-turn conversations in a nuanced domain like user mental health. Very proud to have worked with the team at @TransluceAI to get this report out!
Today, Transluce is releasing the most expansive independent evaluation to date of how AI systems respond to users experiencing mental health crises.
We evaluated 77 model variants from OpenAI, Anthropic, Google, Meta, SpaceXAI, Thinking Machines, DeepSeek and Moonshot AI.
