Abstract

The escalating computational costs of large language models (LLMs) have catalyzed the pursuit of more efficient alternatives, particularly in specialized domains like biomedicine. In this study, we propose BioQwen, a series of small-parameter biomedical bilingual (Chinese–English) multi-task models designed to mitigate the resource demands of LLMs while achieving high performance.
BioQwen is trained on carefully curated open-source biomedical datasets, employing a stringent preprocessing pipeline with thorough quality filtering and standardized formatting. Through an efficient two-stage fine-tuning strategy, BioQwen models with 0.5B, 1.5B, and 1.8B parameters attain competitive performance across a variety of comprehension and generative tasks. For comprehension tasks, BioQwen-1.8B achieves a Macro F1 score of 0.730 and a balanced accuracy of 0.802 on the BC5CDR dataset, surpassing the 7B-parameter Taiyi model’s scores of 0.685 and 0.757. In generative tasks, BioQwen delivers superior zero-shot results on the iCliniq dataset, outperforming all baselines across multiple metrics. Comparisons with established small-parameter LLMs (e.g., Llama3.2 1B) further substantiate the effectiveness of domain-specific fine-tuning.
Significantly, BioQwen’s reduced iteration time highlights its computational efficiency, and its quantized version demonstrates successful deployment on mobile devices, confirming its viability in resource-constrained settings. This study demonstrates the potential of strategically fine-tuned small-parameter LLMs to deliver resource-efficient, high-performing solutions for biomedical bilingual applications, expanding accessibility and usability in the field.
