Capabilities

Updated antibody Fv predictor. Input: heavy and light chain sequences; output: an Fv structure plus a per-residue predicted error (RMSD) estimate, so you can tell which CDR loops to trust before docking.

When to use it

Use when you want Fv models plus a calibrated confidence estimate per residue. Weight-file terms were not separately stated, and like other Fv models CDR-H3 is the limiting region.

Commercial Licensing

Commercial rights — may a company use it?

Commercial use OK

Licence as writtenApache License 2.0

LICENSE.txt in the repo is Apache-2.0; permissive, commercial use allowed.

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

Commercial cost — is commercial use free of charge?

Free for commercial use

Nothing to pay: the licence read at the source grants commercial use with no fee, and the code and weights are public downloads. You still pay for your own compute.

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

  • Commercial OK ≠ Free of charge. A tool can be licensed for company use and still need a paid licence for a dependency (BindCraft → PyRosetta).
  • Free download ≠ Commercially licensed. Weights you can download at no cost may still forbid commercial use (AlphaFold 3).
  • Unverified ≠ Commercially permitted. If no published statement settles it, treat it as unknown — not as a yes.
  • Every component counts. Each status considers the code licence, the model-weights terms, required dependencies and any terms of use.

Model Weights

Weights: unverified. A separate weights licence is Not documented as its own field; where weights carry different terms from the code, that is stated in the licence explanation above.

Dependencies

Not documented as a separate field. Any dependency that affects commercial use (for example a paid PyRosetta licence) is named in the licence and cost explanations above.
