Health AI safety layer reduces benchmark scores, reveals bugs

By PulseAugur Editorial · [1 sources] ·

A developer building a health AI assistant named Tabibu found that its safety layer, designed to prevent dangerous outputs, actually lowered its score on the HealthBench benchmark. The safety layer, which includes features like emergency escalation and refusing prescription doses, was penalized for not being as comprehensive as the bare language model. This occurred because HealthBench rewards completeness, such as providing specific dosages and diagnoses, which the safety layer intentionally avoids to enhance user safety. AI

IMPACT Safety layers in health AI may be penalized by current benchmarks, potentially leading developers to prioritize completeness over safety.

    We ran HealthBench on our health AI's safety layer. It scored lower than the bare model.

    <p>I build Tabibu, a health-information assistant. It adds a safety layer on top of a language model: emergency escalation, refusing prescription doses, answering from retrieved sources, and a reviewer that checks the output. I wanted to know what that layer costs on a public ben…
