ChemGPT 4.7M

ChemGPT is based on the GPT-Neo model and was introduced in the paper Neural Scaling of Deep Chemical Models .

Model description

ChemGPT is a transformers model for generative molecular modeling, which was pretrained on the PubChem10M dataset.

Intended uses & limitations

How to use

You can use this model directly from the ?/transformers library.

Limitations and bias

This model was trained on a subset of molecules from PubChem. You can use this model to generate molecules, but it is mostly intended to be used for investigations of the effects of pre-training and fine-tuning on downstream datasets.

Training data

PubChem10M, a dataset of SMILES strings from PubChem, available via DeepChem .

Training procedure

Preprocessing

SMILES strings were converted to SELFIES using version 1.0.4 of the SELFIES library.

Pretraining

See code in the LitMatter repository .
