Conceptual task guide. Dataset preparation, parameters and scoring must come from a separately identified protocol.

Choosing an evaluation

Define the endpoint before comparing numbers. Boltz-2 distinguishes a binder-versus-decoy probability from a quantitative affinity output, with different supervision. Preserve measurement units, transforms and assay conditions. Structural plausibility alone does not validate affinity; a structural dataset also needs checked affinity labels before it can support this task.

Task scope

This is a task guide, not a single versioned benchmark protocol. The connected resources provide examples or concrete procedures. A candidate method or proposed control is not evidence that an evaluation has been completed.

What is still missing

  • Binding probability, mixed-measure affinity regression and virtual-screening enrichment are different outcomes.
  • Affinity head mixes biochemical quantities; values are not automatically assay-calibrated Kd.
  • No paper-wide universal affinity score or common ligand denominator.
