# An internal Claude model designed 17 lab-confirmed binders against scorpion neurotoxins in a 64-hour mostly autonomous campaign

Claude generated 318,484 candidates with 12 design tools, and 17 of the 211 designs sent to the wet lab met strict binding criteria, though Anthropic ran no neutralization tests.

Anthropic reported on October 20 that it gave an internal Claude research model a task: design minibinders against five scorpion neurotoxins from species found in Mexico, Brazil, North Africa and the Middle East. Working largely on its own…
