About this model
OpenFold matches AlphaFold2 accuracy from a clean-room retraining, released under Apache 2.0. When licensing is the deciding constraint rather than raw accuracy, this is the structure predictor to reach for.
Standardized I/O contract
Every model in the Hub speaks the same contract, which is what lets the Router and the agent call any of them without special-casing.
Inputs
Protein sequence
Outputs
All-atom coordinates in PDB format, viewable and downloadable.
pLDDT score per residue (0–100). Above 70 is generally reliable.
