How to install

  • Claude Science — enable the built-in OpenFold3 research skill (Anthropic-hosted; not published to the public anthropics/life-sciences marketplace).
  • Run the model yourself — the upstream model is open source:
    git clone https://github.com/aqlaboratory/openfold
    

    Follow the repo README for environment setup and model weights.

What it does

Runs OpenFold3, the open reimplementation/extension of the AlphaFold architecture, to predict protein and complex structures. MSA generation runs locally (jackhmmer) or via the ColabFold API; there is no vendor inference API.

Primary use cases: Open-source structure prediction, reproducible folding pipelines, complex modelling

Notes

Claude Science: Featured as a research skill in Anthropic’s Claude Science. Its inclusion there is an independent signal of quality and trustworthiness for life-science work.

Local (your compute); GPU recommended. Fully open training/inference stack.
