BenchBench-Protocol - Staining, Imaging, and Cytometry: leaderboard

BenchBench-Protocol (Benchling, 2026) derives 149 wet-lab protocol-modification tasks from changes scientists made to published protocols, each graded against weighted rubric elements by a GPT-5.6 Terra judge. This board covers the 24 tasks from the staining, imaging, and cytometry domain. Normalized rubric score in percent; higher is better.

Metric: Normalized rubric score (%; weighted rubric elements met by the response to real protocol-modification tasks in the staining, imaging, and cytometry domain (24 tasks), graded by GPT-5.6 Terra; mean of repeated attempts per task). Source: arxiv.org. Saturation forecast: Around September 2027. 9 models tracked.
