## 重写摘要
MOSAIC 的目标不是预测一个反应产物，而是生成真正可执行的实验协议。论文把分散在海量反应流程中的知识组织成“多专家集体智能”框架，用来输出可复现、可执行、且附带置信度的化学合成方案。作者强调系统建立在数百万 reaction protocols 的集体知识之上，而不是只做语言表面上的模板匹配。
论文里最关键的结果，是实验验证展示了超过 35 个新化合物的实现，覆盖药物、材料和农化等多个方向。这说明它的价值已经从“AI 会不会写 protocol”推进到“AI 写出的 protocol 能不能真的做出来”。
## 为什么重要
化学自动化真正稀缺的往往不是反应式，而是步骤顺序、条件选择、后处理和失败恢复。MOSAIC 处理的是实验知识最昂贵、最难结构化的部分，因此平台效应很强。
## 局限
这类系统极易受到文献偏倚和专利表达风格影响。高置信不等于高成功率，落地时仍然必须保留人工审核和实验安全门槛。
原始摘要
The exponential growth of scientific literature presents an increasingly acute challenge across disciplines. Hundreds of thousands of new chemical reactions are reported annually, yet translating them into actionable experiments becomes an obstacle . Recent applications of large language models (LLMs) have shown promise , but systems that reliably work for diverse transformations across de novo compounds have remained elusive. Here we introduce MOSAIC (Multiple Optimized Specialists for AI-assisted Chemical Prediction), a computational framework that enables chemists to make use of the collective knowledge of millions of reaction protocols. MOSAIC is built on the Llama-3.1-8B-Instruct architecture , training 2,498 specialized chemical experts in Voronoi-clustered spaces. This approach delivers reproducible and executable experimental protocols with confidence metrics for complex syntheses. With an overall 71% success rate, experimental validation demonstrates the realizations of more than 35 new compounds, spanning pharmaceuticals, materials, agrochemicals and cosmetics. Notably, MOSAIC also enables the discovery of new reaction methodologies that are absent from the expert’s training, a cornerstone for advancing chemical synthesis. This scalable model of partitioning vast domains into searchable expert regions enables a generalizable strategy for AI-assisted discovery wherever accelerating information growth outpaces efficient knowledge access and application.
