AI总结:

针对科学文献爆炸与通用大模型领域适应性不足的问题,本文提出SciGPT模型与ScienceBench基准,通过领域蒸馏、稀疏专家注意力和知识感知自适应,在科学任务上超越GPT-4o,助力AI科学发现。

摘要:

科学文献呈指数级增长,给研究人员高效综合知识造成了严重瓶颈。虽然通用大语言模型(LLM)在文本处理方面展现出潜力,但它们往往无法捕捉科学领域特有的细微差别(如技术术语、方法论严谨性),并且在处理复杂科学任务时存在困难,限制了其在跨学科研究中的实用性。为解决这些不足,本文提出了SciGPT,一个面向科学文献理解的领域自适应基础模型,以及ScienceBench,一个专为评估科学大语言模型而设计的开源基准。基于Qwen3架构,SciGPT融合了三项关键创新:(1)通过两阶段流程实现低成本领域蒸馏,以平衡性能与效率;(2)稀疏混合专家(SMoE)注意力机制,在32,000词元的长文档推理中将内存消耗降低55%;(3)知识感知自适应,整合领域本体以弥合跨学科知识鸿沟。在ScienceBench上的实验结果表明,SciGPT在核心科学任务(包括序列标注、生成和推理)上优于GPT-4o。它还在未见过的科学任务中表现出强大的鲁棒性,验证了其促进人工智能增强科学发现的潜力。

英文摘要:

Scientific literature is growing exponentially, creating a critical bottleneck for researchers to efficiently synthesize knowledge. While general-purpose Large Language Models (LLMs) show potential in text processing, they often fail to capture scientific domain-specific nuances (e.g., technical jargon, methodological rigor) and struggle with complex scientific tasks, limiting their utility for interdisciplinary research. To address these gaps, this paper presents SciGPT, a domain-adapted foundation model for scientific literature understanding and ScienceBench, an open source benchmark tailored to evaluate scientific LLMs. Built on the Qwen3 architecture, SciGPT incorporates three key innovations: (1) low-cost domain distillation via a two-stage pipeline to balance performance and efficiency; (2) a Sparse Mixture-of-Experts (SMoE) attention mechanism that cuts memory consumption by 55\% for 32,000-token long-document reasoning; and (3) knowledge-aware adaptation integrating domain ontologies to bridge interdisciplinary knowledge gaps. Experimental results on ScienceBench show that SciGPT outperforms GPT-4o in core scientific tasks including sequence labeling, generation, and inference. It also exhibits strong robustness in unseen scientific tasks, validating its potential to facilitate AI-augmented scientific discovery.
