AI Agents Find CRISPR-Like DNA in Giant Viruses
A Thousand Agents, One Day, and a Viral Sequence
Anthropic, the artificial intelligence company headquartered in San Francisco, California, has established a biology “wet lab” where human scientists and AI agents collaborate to design and conduct experiments. [1] The company announced the new laboratory and released a preprint on 25 September 2026. [1] The preprint has not yet been peer reviewed. [1] The work offers a first look at how Anthropic’s new life sciences research group intends to mine enormous genomic datasets in search of novel molecular tools.
The detection effort enlisted roughly 950 AI agents that spent more than 21 hours combing through DNA sequence databases. [2] These agents identified a peculiar pattern of DNA in the genomes of several giant viruses. [2] Similar patterns appear in DNA encoding the CRISPR immune systems of some microbes — systems that scientists have already developed into powerful genome-editing tools. [2]
What distinguishes this search from conventional bioinformatics is its scale and autonomy. Instead of a single researcher querying a database, nearly a thousand independent software agents worked in parallel for the better part of a day. The result was not a confirmed function but a candidate: a sequence worth investigating further. Finding a pattern that resembles a known tool is not the same as demonstrating that the pattern does what the known tool does.
