Figure 2C reports n=2,573 scored ligands on the intersection where all models produced valid predictions, after excluding undefined SuCOS scores. Multiple ligands in one system are scored independently. Five seeds × five diffusion samples per target; select top candidate by ipTM. Success requires lDDT-PLI >0.8 and BiSyRMSD <2 angstrom. Baselines use 10 recycles and 200 diffusion steps; ESMFold2 uses 10 or 20 loops as labelled and truncated 68-step diffusion. Single-sequence and MSA conditions remain separate.

How it works
How it works
ESMFold2 predicts biomolecular structures from protein, DNA, RNA and ligand inputs, optionally using protein alignments. ESM C 6B embeddings coupled to a diffusion-based structure prediction architecture. The documented inputs are protein, DNA/RNA, modified-residue and small-molecule specifications; optional protein MSAs for the full variant. The output consists of all-atom complex coordinates with confidence estimates and optional distogram predictions.

ESMFold2 supports optional MSA conditioning; ESMFold2-Fast is a distinct single-sequence inference variant. The applicable input limits require configuration-specific checking.

Strengths and limitations
Strengths and considerations
- Supports both sequence-only prediction and an MSA-assisted mode.

Limitations and conditions
- The 6B figure describes the ESM C backbone, not a verified parameter total for the complete folding system. Sequence-only and MSA-assisted runs need separate evaluation identities.
