A new research paper explores the universality of scaling laws for machine-learned interatomic potentials (MLIPs), finding that while power-law scaling improvements are observed with increased data, the specific exponent, error floor, and sample efficiency are influenced by model architecture, target quantity, data sampling policy, and test set distribution. The study highlights that structure count alone is insufficient for scaling MLIPs, emphasizing that the value of additional data depends on its chemical and configurational content relative to the model's intended use. Different sampling strategies can yield varying results, with some improving cross-dataset performance while others degrade in-distribution performance. AI
