Pretrained FAIRChem models#

This page summarizes all the pretrained models released as part of the Open Catalyst Project. All models were trained using this codebase.


Open Catalyst 2020 (OC20)#

  • All configurations for these models are available in the configs/ directory.

  • All of these models are trained on various splits of the OC20 S2EF / IS2RE datasets. For details, see https://arxiv.org/abs/2010.09990 and https://github.com/FAIR-Chem/fairchem/blob/main/DATASET.md.

  • All OC20 models are trained on adsorption energies, i.e. the DFT total energies minus the clean surface and gas phase adsorbate energies. For details on how to train models on OC20 total energies, please read the referencing section here.

  • All configurations for these models are available in the configs/oc22 directory.

  • All of these models are trained on various splits of the OC22 S2EF / IS2RE datasets. For details, see https://arxiv.org/abs/2206.08917 and https://github.com/FAIR-Chem/fairchem/blob/main/DATASET.md.

  • All OC22 models released here are trained on DFT total energies, in contrast to the OC20 models listed above, which are trained on adsorption energies.

The models in the table above were trained to predict relaxed energy directly. Relaxed energies can also be predicted by running structural relaxations using the S2EF models from the previous section.

IS2RS#

The IS2RS is solved by running structural relaxations using the S2EF models from the prior section.
