This is an unofficial implementaion of AlphaFold 3 on Google Colab using Jupyter runtime. It makes the folding parameters smooth and interactive without the need to json files editing. Simulating the I/O interface featured in ColabFold.
According to the terms of use. This implementation could only be ran locally and you have to request AlphaFold 3 parameter from the AlphaFold 3 team. This repo does not contain any confidential files from AlphaFold 3 team. This repo is based on the AlphaFold3.
See the updated installation documentation.
This repository contains all necessary code for AlphaFold 3 inference. To request access to the AlphaFold 3 model parameters, please complete this form. Access will be granted at Google DeepMind’s sole discretion. We will aim to respond to requests within 2–3 business days. You may only use AlphaFold 3 model parameters if received directly from Google. Use is subject to these terms of use.
See the input documentation.
See the output documentation.
See the performance documentation.
This package provides an implementation of the inference pipeline of AlphaFold 3. See below for how to access the model parameters. You may only use AlphaFold 3 model parameters if received directly from Google. Use is subject to these terms of use.
Any publication that discloses findings arising from using this source code, the model parameters or outputs produced by those should cite the Accurate structure prediction of biomolecular interactions with AlphaFold 3 paper.
Please also refer to the Supplementary Information for a detailed description of the method.
AlphaFold 3 is also available at alphafoldserver.com for non-commercial use, though with a more limited set of ligands and covalent modifications.
If you have any questions, please contact the AlphaFold team at [email protected].
Known issues are documented in the known issues documentation.
Please create an issue if it is not already listed in Known Issues or in the issues tracker.
