Anthropic's AI Model Claude Discovers CRISPR-Like Enzyme System
Confirmed
In Short: Anthropic announced its AI model Claude discovered a novel enzyme system with properties similar to CRISPR.
Anthropic on Wednesday said its AI model Claude helped discover a novel enzyme system with properties reminiscent of mechanisms in gene-editing technology CRISPR, marking the first result from the company's biology research efforts.
The finding comes days after Reuters reported Anthropic had quietly established a wet lab in the San Francisco Bay Area, expanding its ambitions in life sciences and drug-related research.
Anthropic CEO Dario Amodei said Claude discovered the system after spending 21 hours searching a large database of DNA sequences.
Claude's discovery involved nearly 950 agents working through 210 million tokens before one spotted an unusual repeating pattern in the dataset and flagged it for human review.
Further analysis and lab testing revealed a previously uncharacterized enzyme system found in bacteriophages, a type of virus that infects bacteria.
The company said Claude's involvement was limited to the initial prompt and the lab work, while Claude agents combed the database, investigated distinct RT families, and used their own judgment to identify candidates.
Anthropic said this type of analysis can take an expert scientist weeks to months.
The underlying RT, found in a jumbo phage, had been identified in previous studies, but Anthropic said Claude appears to be the first to notice the system’s defining features.
The system’s set of characteristics has only ever been found together in a handful of other systems, all of which are programmable and perform operations such as cutting, copying, and pasting DNA.
Anthropic said it had not determined the function of the system, but it suspects the “molecular machine” could “represent a new gene editing mechanism.”
What this adds
Anthropic's Claude AI now leads 26% of the company's research and development, up from nearly none earlier this year.
The push comes as Anthropic seeks to attract more scientists to its lab and expand into areas like drug discovery.
The company formed the research group in the spring of 2026 to test whether general AI models can systematize and accelerate biological discovery.
Background
Anthropic's Claude AI now leads 26% of the company's research and development, up from nearly none earlier this year.
What's confirmed
- Further analysis and lab testing revealed “a previously uncharacterized enzyme system found in bacteriophages,” a type of virus that infects bacteria.
What's still developing
- Anthropic, which is at the centre of a vigorous global debate about how to maximise the benefits of AI while mitigating catastrophic risks, said it had not determined the function of the system.
- “Nature contains an enormous diversity of molecular systems we barely understand, and some patterns are very complicated but highly meaningful; AI could greatly expand our ability to explore them more effectively and rapidly, in this case, in just 21 hours,” he said.
- “Because the identified array is ‘CRISPR-like’, some have leaped to conclude Anthropic discovered the ‘next CRISPR’ – ie, a Nobel Prize-winning gene editing technology,” Blake told Al Jazeera.
- “CRISPR-the-technology is very different from CRISPR in nature, which is basically a bacterium’s immune system. It has long been known that there are countless CRISPR-like sequences we have yet to identify and catalogue because there are millions of bacterial species we have yet to study,” Blake said.
- It’s the first result from Anthropic’s newly-launched wet lab and an early test of Claude’s usefulness for science as the company prepares to go public.
- The admittedly premature announcement comes as Anthropic seeks to attract more scientists to its lab and expand into areas like drug discovery.
- The push comes as AI companies increasingly turn to scientific research to prove the value of their more capable models.
- The company said it believes that acceleration will come from a new way of doing biology research in which AI agents collaborate with humans at every step, and that developing this approach required building its own laboratory and a single team working on everything from training Claude in biology to running experiments.
- Before joining Anthropic, team members’ research contributed to understanding the evolution and regulation of CRISPR systems, discovering new enzymes for next-generation cell and gene therapies, and building tools to speed the identification of anomalies in DNA such as human pathogenic variants.
- The announcement placed the result in a line of past discoveries that began with a scientist noticing something unusual in nature’s molecular machines: restriction enzymes found in bacterial immune systems, Taq polymerase identified in a bacterium in a Yellowstone hotspring and later used as the basis for PCR, and CRISPR itself, first noticed as an unusual repeat sequence in bacterial DNA.
- The company said that with hundreds to thousands of candidate reports arriving from a single campaign, the hypotheses themselves have become an object of study, with lessons fed back into the instructions given to Claude.
- Anthropic formed the research group in the spring of 2026 to test whether general AI models can systematize and accelerate biological discovery.
