Abstract Scope

Custom Generative pre-trained transformers (GPTs) are transforming domain-specific problem-solving across scientific fields. However, materials science lacks a dedicated, accessible GPT-based assistant tailored to its unique challenges. ChatGPT Material Explorer 1.0 (CME), a custom GPT that integrates large language models with graph neural networks (GNN) models and other domain-specific APIs to enhance materials design workflows. The assistant offers core functionalities such as: (1) intelligent exploration of molecular and materials databases, (2) GNN-driven prediction of materials properties, (3) efficiently searching arXiv for papers, and (4) interactive, conversational support for scientific analysis and writing. I evaluate its performance against general-purpose models such as OpenAI GPT-4o highlighting its superior ability to retrieve accurate data, reduce hallucination, and provide context-aware responses. More details about CME are available at: https://github.com/AtomGPTLab/chatgpt_material_explorer to facilitate broader community adoption.
