Anthropic says Claude designed 17 scorpion-toxin binders

On Oct. 20, 2026 Anthropic said an internal Claude research model designed protein minibinders against scorpion neurotoxins, and that Adaptyv Bio and Twist Bioscience tested 211 designs. Seventeen met Anthropic's binding criteria. Anthropic says it has not tested neutralization in cells or animals and does not claim an antivenom; a participating account also said broader tests flagged some designs as potentially sticky.
