  1. The numbers are the calculated energy, force and stress mean absolute errors (MAEs) of M3GNet, TensorNet, and CHGNet compared to DFT. The numbers are listed in the order of training, validation, and test. The dataset was divided into training, validation, and test sets with a split ratio of 0.9, 0.05, and 0.05, respectively.
