New framework stresses medical LLMs, reveals hidden safety flaws

A new stress-testing framework called AI-MASLD has been developed to evaluate the safety of medical large language models beyond standard accuracy benchmarks. The framework revealed significant performance divergences among seven tested models when subjected to realistic narrative stress, uncovering two distinct stress-response phenotypes. Notably, fine-tuning on medical data degraded logical stability, while an open-weight model matched or surpassed proprietary alternatives in safety metrics, highlighting the necessity of narrative stress auditing.

    Stress-testing medical large language models reveals latent safety pathology beyond benchmark accuracy

    arXiv:2606.07929v1 Announce Type: new Abstract: Large language models (LLMs) are entering clinical practice based on benchmark accuracy that may fail to detect safety-relevant failure modes. Here we present AI-MASLD, a stress-audit framework that adapts the logic of metabolic str…
