Jaehwan Choi, Seongmin Kim, and Yousung Jung present SynCry-GPT—an LLM that doesn’t just predict if a crystal can be synthesized, but actually redesigns unsynthesizable structures into feasible ones, bridging the gap between theory and experiment. pubs.acs.org/doi/10.1021/...
Synthesis-Aware Materials Redesign via Large Language Models
We propose a novel framework that leverages large language models (LLMs) to transform synthetically infeasible inorganic crystal structures into synthetically feasible ones. Unlike previous studies on...
