AI总结:

本文评估了多种大型语言模型在医疗问答任务中的性能,发现大模型表现更优,同时指出在实际部署中需权衡效率与避让问题。

摘要:

最近,大型语言模型(LLMs)在医疗领域获得了显著关注,特别是在开发用于医疗问答系统的问答系统以提高低资源环境中的医疗服务可及性。本文比较了从2024年4月至2025年8月期间部署的五个LLM,使用包含38,000个跨专科医学问题和答案的iCliniq数据集。我们的模型包括Llama-3-8B-Instruct、Llama 3.2 3B、Llama 3.3 70B Instruct、Llama-4-Maverick-17B-128E-Instruct以及GPT-5-mini。我们采用零样本评估方法,并使用BLEU和ROUGE指标来评估性能,而无需专门的微调。我们的结果表明,较大的模型如Llama 3.3 70B Instruct优于较小的模型,这与临床任务中观察到的扩展效益一致。值得注意的是,Llama-4-Maverick-17B表现出更具竞争力的结果,从而突显了在实际部署中效率与避让之间的权衡。这些发现与LLM能力向专业水平医疗推理的进展一致,并反映了LLM支持的问答系统在真实临床环境中的日益可行。本基准旨在为未来研究提供标准化设置,以减少模型大小、计算资源并最大化医疗NLP应用中的临床效用。

英文摘要:

Recently, Large Language Models (LLMs) have gained significant traction in medical domain, especially in developing a QA systems to Medical QA systems for enhancing access to healthcare in low-resourced settings. This paper compares five LLMs deployed between April 2024 and August 2025 for medical QA, using the iCliniq dataset, containing 38,000 medical questions and answers of diverse specialties. Our models include Llama-3-8B-Instruct, Llama 3.2 3B, Llama 3.3 70B Instruct, Llama-4-Maverick-17B-128E-Instruct, and GPT-5-mini. We are using a zero-shot evaluation methodology and using BLEU and ROUGE metrics to evaluate performance without specialized fine-tuning. Our results show that larger models like Llama 3.3 70B Instruct outperform smaller models, consistent with observed scaling benefits in clinical tasks. It is notable that, Llama-4-Maverick-17B exhibited more competitive results, thus highlighting evasion efficiency trade-offs relevant for practical deployment. These findings align with advancements in LLM capabilities toward professional-level medical reasoning and reflect the increasing feasibility of LLM-supported QA systems in the real clinical environments. This benchmark aims to serve as a standardized setting for future study to minimize model size, computational resources and to maximize clinical utility in medical NLP applications.
