# Model Card for Model ID

This repository contains the FlashMD universal models. These are models designed to run accelerated molecular dynamics for chemical systems across the periodic table.

## Model Details

These models offer acceleration with respect to traditional molecular dynamics by allowing the use of larger steps. Each FlashMD model follows the following naming
convention: `flashmd_{mlip}_{timestep}fs.ckpt`, where "mlip" is the name of the MLIP (machine-learned interatomic potential) that was used to generate the training
trajectories for the FlashMD model, and {timestep} is the FlashMD timestep in fs. The corresponding MLIP is also made available as `mlip_{mlip}.ckpt`.

At the moment, we have:

- mlip = "pet-omatpes" (with timestep={1,2,4,8,16,32,64,128}): these are FlashMD models trained on the PET-OMATPES MLIP, and therefore allowing to run FlashMD at the
  r2SCAN level of theory
- earlier models used in the reference paper ("flashmd_{timestep}fs.pt", with timestep={1,4,8,16,32,64}), only supported by `flashmd<=0.1.2` and useful to reproduce
  older results. These are trained on the PET-MAD MLIP and therefore reproduce molecular dynamics at the PBEsol level of theory
