Citrini Research uses internal Anthropic Claude model to design scorpion toxin binders
Investment research firm Citrini Research collaborated with Anthropic to autonomously design protein minibinders targeting scorpion neurotoxins, resulting in 17 lab-confirmed binding designs.

Investment research firm Citrini Research teamed up with AI developer Anthropic to test whether an unreleased bio-research model could autonomously design functional proteins for a scorpion antivenom. Citrini spent three months and $200,000 using the Claude model to engineer proteins, according to Quartz. Following the project's laboratory results, the hedge fund is now purchasing biotechnology stocks.[6][5][2]
Anthropic granted Citrini access to its internal Claude research model to generate protein minibinders targeting scorpion neurotoxins. Armed with a starting prompt, follow-up directions, and specialized tools, the model generated 300 sub-agents and autonomously ran a design campaign. Over roughly 64 hours, Claude evaluated docking targets, produced more than 318,000 protein candidates, and determined which designs warranted physical experimentation.[1][2][3][4]
Physical laboratories evaluated 211 candidate proteins, including options added with human assistance. The testing confirmed that 17 designed proteins successfully attached to target molecules, with binders acting across four toxins. Anthropic framed the collaboration as a continuation of its protein engineering work, noting it had demonstrated Claude designing protein minibinders from a single prompt in August.[1][2][3][4][6]

Anthropic’s internal Claude research model carried out much of a research project on its own, with results confirmed in the lab. This is the beginning of autonomous AI scientists making their own discoveries. Given a starting prompt and four follow-ups, Claude used specialized tools to generate more than 318,000 protein designs in 64 hours. It chose where they should attach to scorpion toxins and selected candidates for testing. Labs tested 211 candidates, including additions made with human help. Seventeen successfully attached to their target toxins. These are "binders", small proteins that latch onto another molecule. Claude handled a substantial stretch of research: choosing an approach, coordinating tools and deciding what deserved a physical experiment. From here on it only gets more autonomous. I am so excited!
