Clinical LLMs evaluated for semantic stability in diagnosis

Researchers have developed a new framework to evaluate the semantic stability of clinical Large Language Models (LLMs). This framework uses Natural Language Inference (NLI) to filter prompt variations that preserve clinical meaning, addressing the risk of LLMs producing inconsistent diagnoses due to subtle linguistic changes. The study evaluated 16 LLMs, finding that domain specialization does not consistently guarantee improved robustness, with some general-purpose models remaining competitive. AI

IMPACT Highlights critical safety concerns for LLMs in healthcare, emphasizing the need for robust evaluation beyond simple semantic similarity.

    Same Patient, Different Words, Different Diagnosis? Evaluating Semantic Stability in Clinical LLMs

    arXiv:2605.30646v1 Announce Type: cross Abstract: Large Language Models (LLMs) are increasingly used in clinical applications. However, their behavior remains highly sensitive to subtle linguistic variations, such as rephrasing or syntactic variation. This sensitivity poses risks…
