Five Pharma Firms Federally Fine-tune OpenFold3, Lifting Ligand-Pose Accuracy 29% to 47%

Five pharma companies fine-tuned OpenFold3 in a federated setting on 20,000+ structures, raising correct ligand-pose predictions from 29% to 47% — the model improved dramatically once trained on private pharma data. The post argues protein-ligand structure prediction isn't solved: models only work well where training data is dense, and claims of broad generalization in other bio foundation models deserve skepticism given protein structure's unusually good data curation, labels, and physical constraints.
