Design success
40%estimated progressWhat we track
Experimentally functional designs / all synthesized AI proposals, with explicit activity, stability, and specificity requirements.
Why this estimate?
Experimentally successful binders demonstrate strong bounded design capability across targets. People still choose targets, run acceptance assays and establish broader biological utility.
Advancements
- AlphaProteo binds 7 target proteins, with an 88% wet-lab success rate on BHRF1September 5, 2024. Google DeepMind reported that AlphaProteo designed binders for seven target proteins with 3 to 300 times better binding affinity than the best existing methods, including an 88% experimental success rate for candidates against the viral protein BHRF1. It failed to produce successful binders against an eighth target, TNF-alpha.
- BindCraft designs protein binders with 46% average success2025 publication. BindCraft reports target-specific experimental binder success rates of 10–100%, averaging 46.3%, with affinities predominantly in the nanomolar range.
- Designed serine hydrolases reach kcat/KM of 2.2x10^5 with sub-angstrom structural match2025. Lauko, Pellock et al., Science 388, eadu2454, report computationally designed serine hydrolases with catalytic efficiencies (kcat/KM) up to 2.2 x 10^5 M-1 s-1, whose crystal structures match the design models with C-alpha RMSDs below 1 angstrom.
- RFantibody designs antibodies that bind C. difficile toxin at mid-nanomolar affinityNovember 5, 2025. The UW Institute for Protein Design reported RFdiffusion-designed antibodies against bacterial toxins, influenza and coronavirus proteins and cancer targets; anti-Clostridium difficile toxin designs showed mid-nanomolar affinity and retained potency as full IgG. Of five designed antibodies imaged with their targets, four matched the computational predictions closely.
Read the dated findings and sources
Status: Measured experimental design success. Sources accessed November 7, 2026. This is a documentary baseline, not an independent replication or an assertion of the worldwide best result. An unknown measurement is not zero.

Interpretation and tracking value
The reported average is not a pooled success fraction for every generated or synthesized design, and binding alone does not establish all activity, stability and specificity requirements.
Next comparable measurement
Record all synthesized designs per target; require prespecified binding, function, stability and off-target thresholds and independent assay replication. Preserve this dated observation; append future results with their model/system version, denominator, budget and evidence level rather than overwriting it.
