RFdiffusion3
All-atom generative diffusion model for designing proteins, nucleic acid binders, and enzymes with precise non-protein interaction conditioning.

RFdiffusion3 (RFD3) is a fully atom-based diffusion model that generates protein structures—including explicit side chains—in the context of nucleic acids, small molecules, and other non-protein atoms. By modeling all polymer atoms explicitly, RFD3 enables precise conditioning on complex atom-level constraints, such as hydrogen bond donor/acceptor status and solvent accessibility. The model utilizes a streamlined architecture to achieve state-of-the-art performance on protein, ligand, and DNA binder design benchmarks while operating at approximately one-tenth the computational cost of RFdiffusion2.

Key Capabilities
- Fully atomistic generation creates protein backbones and side chains simultaneously, enabling precise modeling of interactions.
- Advanced atom-level conditioning allows direct control over hydrogen bonding, solvent accessibility (RASA), and center-of-mass positioning.
- Streamlined architecture (approx. 168M parameters) delivers a 10-fold speed increase over RFdiffusion2 without sacrificing performance.
- Demonstrated success in designing high-affinity binders, symmetric oligomers, and enzymes with complex active site scaffolding.
