Claude’s Protein Design Hit Rate Was 26.8%. One Target Returned 0 for 90.

Author(s): Decoding AI Originally published on Towards AI. We refit Anthropic’s published per-target protein design counts on Aug 25, 2026. Ninety designs went into the wet lab against maltose-binding protein. Ninety came back with nothing. That is the part of the story that stopped us. On August 18, 2026, Anthropic published the results of an autonomous protein design campaign, and the number everyone repeated was the Claude protein design hit rate: 354 binders out of 1,320 designs, 26.8%, agai
