CHIMERA-Bench: A Benchmark Dataset for Epitope-Specific Antibody Design

arXiv:2603.13431v3 Announce Type: replace Abstract: Computational antibody design has seen rapid methodological progress, with dozens of deep generative methods proposed in the past three years, yet the field lacks a standardized benchmark for fair comparison and model development. These methods are evaluated on different SAbDab snapshots, non-overlapping test sets, and incompatible metrics, and the literature fragments the design problem into numerous sub-tasks with no common definition. We introduce CHIMERA-Bench: (CDR Modeling with Epitope-guided Redesign), a unified benchmark built around

Why this matters
Why now

The proliferation of deep generative methods for antibody design in recent years necessitates a standardized benchmark to foster methodological progress and fair comparison.

Why it’s important

A unified benchmark like CHIMERA-Bench will accelerate the development of more effective and targeted antibody therapies, impacting pharmaceutical innovation and healthcare outcomes.

What changes

The fragmented landscape of antibody design evaluation will be replaced by a common framework, allowing for clearer progress tracking and identification of superior computational approaches.

Winners
