AlphaFold 2

Original AlphaFold; monomer and multimer structure prediction from sequence.

Google DeepMind

What it does

Predicts protein structure from sequence. Input: FASTA (monomer or multimer); output: 5 ranked all-atom models with pLDDT and PAE, plus MSAs. Still the workhorse for binder-design filtering and the engine inside BindCraft/ColabFold.

Commercial use

Commercial use OK

Licence as writtenApache License 2.0 (code); CC BY 4.0 (model parameters)

README's 'Model Parameters License' section states parameters are made available under CC BY 4.0, which replaced the earlier CC BY-NC 4.0 terms; attribution required. Some mirrored MSA databases carry their own CC BY-SA 4.0 terms.

The licence read at the source allows use by a company. Attribution or copyleft conditions may still apply — read the note.

Is commercial use free of charge?

Free for commercial use

Free: code Apache-2.0, parameters CC BY 4.0 (changed from CC BY-NC in January 2022). Attribution is the only cost.

Price and rights are separate: this panel is about money, the panel above is about permission.

When to use it

Still the workhorse for monomer and protein-protein complex prediction and the engine inside many binder pipelines. Weaker on ligands and nucleic acids than AF3/Boltz-2, and MSA generation is the slow step.
