MLIPilot: LLM-Driven Auto-Research for Machine-Learned Interatomic Potentials

arXiv:2605.30889v1 Announce Type: cross Abstract: Constructing production-quality machine-learned interatomic potentials (MLIPs) requires balancing accuracy, dynamical stability, and computational throughput under constraints that are not captured by a single training loss. We introduce MLIPilot, an auto-research framework in which tool-calling large language models propose hypotheses, edit MLIP training code, launch HPC jobs, and accept or revert changes using a fixed, physically constrained scorecard. We evaluate MLIPilot on MACE potential optimization using both commercial and open-weight L

Why this matters
Why now

The increasing sophistication of large language models and the demand for more efficient materials science research are converging, enabling autonomous scientific discovery. The paper describes MLIPilot, which leverages LLMs to automate hypothesis generation, code modification, and job execution for machine-learned interatomic potentials.

Why it’s important

Automating significant portions of complex scientific research, particularly in materials science, accelerates discovery cycles and reduces the human effort barrier for developing advanced materials. This development could substantially enhance the pace and efficiency of R&D in critical sectors like manufacturing, energy, and defense.

What changes

Traditional materials science research requiring extensive manual iteration and expert knowledge for potential optimization can now be partially or fully automated by AI agents. This automation dramatically speeds up the development and refinement of new materials, impacting various industries that rely on advanced material properties.
