ODesign: The World Model for All-to-All Biomolecular Interaction Design
ODesign is a pioneering generative foundation model that treats the entire biomolecular universe as a unified, programmable system. Developed by the ODesign Team, it moves beyond specialized tools to provide an "all-to-all" design framework. By abstracting proteins, nucleic acids (DNA/RNA), small molecules, and ions into a unified generative token space, ODesign can generate high-affinity binding partners for arbitrary targets with unparalleled precision.
Built upon a state-of-the-art AlphaFold 3-like architecture, ODesign leverages learned structural priors to perform de novo design across multiple biological modalities in a single, cohesive framework.
Key Innovations: Multimodal Generative Intelligence
ODesign replaces disjointed, modality-specific pipelines with a unified world model capable of cross-modality reasoning.
Unified Generative Tokens: Consolidates the minimal chemical units of diverse modalities into a single token space, enabling the design of any molecule type against any target.
Task-Oriented Masking: A hierarchical masking strategy (All, Entity, Token, Atom) provides fine-grained control, from generating entire structures from scratch to scaffolding precise atomic active sites.
Rigid & Flexible Design Modes: Supports Rigid Mode for fixed targets and Flexible Mode for joint co-generation of both the binder and the receptor interface.
Epitope-Specific Guidance: Allows researchers to specify exact "hotspot" residues on a target, guiding the model to design binders that interact with precise biological surfaces.
All-Atom Diffusion Module: Decodes high-dimensional representations into physically plausible 3D Cartesian coordinates at full-atom resolution.
Performance Benchmarks
ODesign consistently outperforms state-of-the-art (SOTA) modality-specific models, achieving an order-of-magnitude leap in design throughput.
Task | Metric | ODesign Result | Key Finding |
Protein Binder Design | Successful Designs/Day | 2,672 | 10x higher throughput than RFDiffusion |
Motif Scaffolding | MotifScore | 35.9 | 38.6% improvement over SOTA methods |
Atomic Scaffolding | Efficiency Gain | 37.5-fold | Enables high-throughput enzyme active site design |
Small Molecule Design | Success Count (SM) | Highest | 48.4x better throughput than SurfGen |
RNA/DNA Design | Success Rate | ~2x Increase | Outperforms specialized models like RNAFrameFlow |
Scientific Breakthroughs in Interaction Design
De Novo Protein & Antibody Engineering
ODesign sets a new standard for protein binder design, generating thousands of filter-passing candidates per GPU day. Its ability to handle "flexible" targets ensures it can optimize binding poses even for receptors with substantial conformational variability.
Programmable Nucleic Acid Aptamers
ODesign is one of the first AI models capable of rational DNA and RNA aptamer design against protein targets. It effectively generates single-stranded sequences that localize around electrostatically complementary regions on protein surfaces.
Cross-Modality Small Molecule Design
Beyond standard protein targets, ODesign generalizes to design small molecules that target DNA and RNA structures—areas previously hindered by severe data sparsity. It successfully reproduces native binding modes, such as aromatic stacking in DNA minor grooves.
