What is EvoDiff?
EvoDiff is a generative diffusion model for protein sequences developed by Microsoft Research and released in September 2023. While AlphaFold predicts structures from sequences, EvoDiff designs new protein sequences from scratch using diffusion modeling — making it the inverse complement to structure prediction.
It's released under the MIT license, free for any commercial use including biotech and pharmaceutical research.
Why EvoDiff Is Trending in 2026
As generative protein design revolutionizes drug discovery, EvoDiff has become a key tool for designing novel enzymes, antibodies, and therapeutic proteins. Combined with AlphaFold for structure validation, it enables a complete design → predict → test loop for protein engineering.
Key Features and Capabilities
EvoDiff supports unconditional protein sequence generation, sequence inpainting (filling missing regions), structure-conditioned design, evolutionary-aware diffusion, and rapid sampling at scale.
Who Should Use EvoDiff?
EvoDiff is built for biotech researchers, pharmaceutical R&D teams, synthetic biologists, drug-discovery engineers, and enzyme designers.
Top Use Cases
Real-world applications include novel enzyme design, therapeutic antibody generation, drug-target binder design, vaccine candidate generation, biocatalyst design for industrial chemistry, and protein engineering for synthetic biology.
Where Can You Run It?
EvoDiff runs on any system with PyTorch. The model is relatively lightweight and runs on a single consumer GPU.
How to Use EvoDiff (Quick Start)
Clone: git clone https://github.com/microsoft/evodiff. Install dependencies, then generate sequences: python generate.py --model EvoDiff_OAR_640M --num_seqs 100 --seq_length 100. Validate generated sequences with AlphaFold for structure.
When Should You Choose EvoDiff?
Choose EvoDiff when you need novel protein sequence generation with controllable conditioning. For structure-driven design, also use ProteinMPNN or RFdiffusion alongside it.
Pricing
EvoDiff is completely free under MIT license.
