Lightweight LLMs Show Promise for Biomedical Named Entity Recognition

ai-technology · 2026-04-30

A new study from arXiv explores the use of lightweight Large Language Models (LLMs) for Biomedical Named Entity Recognition, addressing computational demands and privacy constraints in healthcare. The research evaluates how different output formats affect model performance, finding that lightweight LLMs can achieve competitive results compared to larger models. Instruction tuning across many distinct formats does not improve performance, but certain formats consistently yield better outcomes. The study highlights the potential of lightweight LLMs as effective alternatives for biomedical information extraction.
