Anthropic's protein design PR dissected: open-source models did most of the lifting
teortaxesTex · x · 2026-08-19
Commentators dissected Anthropic's new protein design results, sharing a "no-PR" version: Claude orchestrated a suite of open-source protein design models — PXDesign, RFdiffusion, Genie, BoltzGen — using a 30k-token expert prompt and 12,500 H100-hours, designing binders against 14 of 15 targets with 22–35% hit rates versus a 10–15% baseline.
The core critique: those open-source models came from the Baker lab, Columbia, MIT and ByteDance Seed, many already wet-lab validated before Claude touched them, and some report similar numbers on their own. The orchestration is genuinely impressive, but the ceiling is set by these generators — all sharing a single PDB-shaped distribution — and the narrative overstates Claude's contribution.
