Optimizing Expert-Designed Crystal Graph Networks for Band-Gap Prediction with an Autonomous LLM Research Loop
arXiv:2606.29717v1 Announce Type: cross Abstract: Predicting a material's properties from its structure is a central, fast-advancing problem in computational materials science. A decade of work has produced standard public benchmarks and many published machine-learning models for the task (Dunn et al., 2020). The task's fixed metric and these baselines make it a natural setting for autonomous agent research (Karpathy, 2026). On the MatBench band-gap benchmark ($>$100k crystals), a general-purpose coding agent autonomously built the most accurate model trained without external pretraining, ahea
The rapid advancement of large language models and autonomous agents is enabling them to tackle complex scientific problems previously requiring significant human expert intervention.
This development demonstrates a significant leap in the capability of AI agents to perform scientific research autonomously, potentially accelerating discovery in materials science and other fields.
AI models can now autonomously design, train, and optimize new models that surpass human-engineered solutions in specific scientific benchmarks.
