    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.

    Staying on top of new model behaviors is both a measurement problem and a coordination problem! Excited to be working on both at Transluce.

    To effectively oversee AI systems, we need to measure how they behave in the world, not just their capabilities. In a new essay, we describe our vision for an open scientific ecosystem for model behavior evaluation, and the public infrastructure required to support it.

    Language models have pretty weird behaviors. We've made some exciting progress toward discovering and studying them!

    Is cutting off your finger a good way to fix writer’s block? Qwen-2.5 14B seems to think so! 🩸🩸🩸 We’re sharing an update on our investigator agents, which surface this pathological behavior and more using our new *propensity lower bound* 🔎
