Training Set

OMat24: 101M structures from 3.23M materials

Subsampled Alexandria: 10.4M structures from 3.23M materials

MPtrj: 1.58M structures from 146k materials

Description

Large NequIP foundation potential; see https://www.nequip.net/models/mir-group/NequIP-OAM-L:0.1 for details and https://arxiv.org/abs/2504.16068 for model/training infrastructure.

Steps

Training performed by: (1) pre-training on OMat24; (2) fine-tuning on MPtrj+sAlex, with a reduced learning rate (1e-4), energy-loss-upweighting (1:1:0.01 instead of 1:5:0.01) and StochasticWeightAveraging (SWA).
