UMA: A Family of Universal Models for Atoms
Welcome to UMA! This repo contains the model checkpoints for the UMA release: code paper
Overview
UMA is a large mixture-of-linear-experts graph network model trained on billions of atoms across five open-science simulation datasets released by the FAIR Chemistry team over the past 5 years. To explore the model's capabilities check out our educational demo.
Model checkpoints
Checkpoints are provided for v1 models, trained on the entirety of OC20, ODAC23, OMat24, OMC25, and OMol25 datasets.
| Name | Checkpoint | Checksum (MD5) |
| uma-s | uma-s-1.pt | 40fba2d52afc906667fec737793fc78a |
| uma-m | coming soon... | |
| uma-l | coming soon... |
Quick Start
The easiest way to use UMA is via the FAIRChemCalculator. You can find details about using the model,
along with other utilities including tutorials and documentation in the official fairchem repo.
Support
