ChemGPT-4.7M

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.
