It outputs a numerical representation of input protein sequences that is suitable for downstream tasks. In particular, its output is used for protein folding in the ESMFold model. ESM2 comes in various sizes: 650M parameters, 3B parameters, and 15B parameters. ESM2 was developed and trained by [META](https://github.com/facebookresearch/esm). The larger models tend to result in more accurate results on downstream tasks, however they also have a longer runtime.
