Understand this story
On October 21, 2026, it was reported that Claude autonomously completed an entire round of a protein design project as an agent in Anthropic's Claude Science environment. According to the report, Claude selected the target site on a scorpion venom neurotoxin on its own, drove 12 protein design programs and set scoring thresholds, and selected 180 molecules from the 318,484 generated to send for physical synthesis; of the 211 designs tested by Adaptyv Bio and Twist Bioscience, 17 successfully bound the target toxin. The request was made by Citrini Research, a financial firm with no laboratory or protein expertise. The report also noted that Anthropic did not call it an antivenom, because the tests needed to support that claim have not yet been conducted. There are currently no subsequent developments.

Claude autonomously designed 17 molecules that bind scorpion venom neurotoxins in Claude Science
In Anthropic's Claude Science environment, Claude autonomously completed an entire round of protein design as an agent: it selected the attack sites on scorpion venom neurotoxins on its own, drove 12 protein design programs, set scoring thresholds, and selected 180 molecules from the 318,484 generated to send for physical synthesis; of the 211 designs tested by Adaptyv Bio and Twist Bioscience, 17 successfully bound the target toxin. The request was made by Citrini Research, a financial firm with no laboratory or protein expertise. Anthropic did not call it an antivenom serum because the tests needed to support that claim have not yet been conducted.
