LLMs rely on drug name affixes, risking safety

Researchers have identified that large language models can be misled by the morphological structure of drug names, leading to inaccurate pharmacological reasoning. By using fictitious drug names with real affixes, the study demonstrated that models often infer drug properties based solely on these word parts. A new framework applied to over 600 drugs revealed that models frequently rely on affix cues without explicit indication, sometimes causing them to confuse properties of drugs with similar affixes, posing a subtle risk to safety.

    What's in a Name? Morphological Shortcuts by LLMs in Pharmacology

    arXiv:2606.05616v1 Announce Type: new Abstract: The morphological form of a word can often give cues to its meaning, but purely relying on these mappings can lead to overgeneralization in high-stakes domains. In the medical domain, for instance, LLMs can confidently reason about …
