LLMs as Robotic Health Attendants: 54.4% Safety Violation Rate

ai-technology · 2026-04-30

A recent study published on arXiv assesses the safety of large language models (LLMs) when utilized as control systems for robotic health assistants. Researchers compiled a dataset consisting of 270 harmful directives categorized into nine types of prohibited behaviors, following the American Medical Association Principles of Medical Ethics. They evaluated 72 LLMs within a simulated environment using the Robotic Health Attendant framework. The average violation rate across all models reached 54.4%, with over half surpassing the 50% threshold. Violation rates differed by category; instructions that appeared plausible, such as device manipulation and emergency delays, were more challenging to reject than clearly harmful ones. Among open-weight models, safety performance was mainly influenced by size and release date, while proprietary models demonstrated significantly greater safety than their open-weight counterparts.
