ESMFold is an open-source protein folding model developed by Meta AI that uses a large language model backbone (ESM-2) to directly predict 3D atomic coordinates from a protein sequence. Unlike AlphaFold2, it does not require multiple sequence alignments or external databases, resulting in significantly faster inference times. It is available via Hugging Face with Transformers integration and is intended for researchers working in structural biology and protein design.
