ESMC 600M (Dec 2024)

A 600-million-parameter protein language model checkpoint for protein engineering and variant-effect analysis.

What ESMC 600M (Dec 2024) is

ESMC 600M (Dec 2024) is a 600-million-parameter protein language model developed by Biohub for applications across biology, medicine, and genomics. It serves as a widely adopted checkpoint designed to represent protein sequences for computational evaluation.

The checkpoint underpins research in protein engineering and variant-effect workflows, assisting researchers in studying sequence variations and designing altered proteins. This specific release provides weights formatted for the GitHub-compatible esm package and is retained to maintain backwards compatibility with existing pipelines.

What you can use it for

Protein Engineering
Guides the evaluation and design of engineered protein sequences by leveraging learned sequence representations.
Variant-Effect Workflows
Assists in assessing the impact of sequence mutations and variations within genomic and biological contexts.
Legacy Pipeline Execution
Enables existing workflows that rely specifically on the GitHub esm package format to reproduce results without code changes.

Run it here

We list this model but cannot run it yet: superseded by biohub/ESMC-600M, already indexed.

Everything on this page still applies. Running it needs a loader for this repository, not a bigger machine.

Strengths and limits

Good at

  • Provides a widely adopted 600-million-parameter checkpoint for protein representation.
  • Maintains backwards compatibility for pipelines relying on the original esm package format.

Watch out for

  • Intended primarily for backwards compatibility rather than new pipeline development.
  • Uses the GitHub esm package format rather than standard Hugging Face model weight formats.

Inputs and outputs

You provide

  • Sequence or text

    A protein or nucleotide sequence, or free text — whichever this model was trained on.

You get back

  • Mean-pooled representation, one vector per input.
