OMC25 Dataset

The training and validation splits of the Open Molecular Crystals 2025 (OMC25) dataset are available for download from HuggingFace at https://huggingface.co/facebook/OMC25, under the CC BY 4.0 license, after applying for the repository access on HuggingFace.

The pretrained ML models are also accessible from HuggingFace: eSEN model at https://huggingface.co/facebook/OMC25 and UMA models at https://huggingface.co/facebook/UMA. We provide the pretrained models with a commercially permissive license (with some geographic and acceptable use restrictions).
