传统机器学习方法通过精准性质预测和定向生成加速无机材料设计,但受限于训练数据中的隐含知识,仅能作为单次模型使用。核心挑战在于构建一个能够自主执行完整材料发现周期(从构想到实验、迭代优化)的智能系统。本文提出SparksMatter,一种多智能体物理感知科学推理的自动化无机材料设计模型。该模型能响应用户需求,生成创意、设计并执行实验流程,持续评估与优化结果,并最终提出满足目标的候选材料。SparksMatter还可自我批判与改进,识别研究盲点与局限,建议严格的后续验证步骤,如DFT计算及实验合成与表征,并整合为结构化报告。在热电材料、半导体及钙钛矿氧化物的设计案例中评估其性能。结果显示,SparksMatter能生成符合用户需求的新颖稳定无机结构。与前沿模型对比表明,其在相关性、新颖性和科学严谨性上均表现更优,盲评显示多个真实任务中新颖性显著提升。这证明SparksMatter具备超越现有知识边界,生成化学合理、物理有意义且具创造力的无机材料假设的独特能力。
原文摘要 · Abstract (English)
Conventional machine learning approaches accelerate inorganic materials design via accurate property prediction and targeted material generation, yet they operate as single-shot models limited by the latent knowledge baked into their training data. A central challenge lies in creating an intelligent system capable of autonomously executing the full inorganic materials discovery cycle, from ideation and planning to experimentation and iterative refinement. We introduce SparksMatter, a multi-agent AI model for automated inorganic materials design that addresses user queries by generating ideas, designing and executing experimental workflows, continuously evaluating and refining results, and ultimately proposing candidate materials that meet the target objectives. SparksMatter also critiques and improves its own responses, identifies research gaps and limitations, and suggests rigorous follow-up validation steps, including DFT calculations and experimental synthesis and characterization, embedded in a well-structured final report. The model's performance is evaluated across case studies in thermoelectrics, semiconductors, and perovskite oxides materials design. The results demonstrate the capacity of SparksMatter to generate novel stable inorganic structures that target the user's needs. Benchmarking against frontier models reveals that SparksMatter consistently achieves higher scores in relevance, novelty, and scientific rigor, with a significant improvement in novelty across multiple real-world design tasks as assessed by a blinded evaluator. These results demonstrate SparksMatter's unique capacity to generate chemically valid, physically meaningful, and creative inorganic materials hypotheses beyond existing materials knowledge.
