Anthropic Says Claude Found Something Big in DNA. It Just Doesn't Know What

In brief

• Anthropic says Claude spent 21 hours and roughly 210 million tokens searching DNA databases before flagging an unusual enzyme system it now calls ART
• CRISPR co-inventor Feng Zhang reviewed the pre-print and called the find “genuinely intriguing,”
• However, even CEO Dario Amodei admits the system's “precise function, biotechnological utility (if any), or level of significance is not yet clear.”

Anthropic put out a press release Wednesday saying Claude, its AI model, discovered a new molecular machine hiding in virus DNA. But read past the hype and CEO Dario Amodei admits its "precise function, biotechnological utility (if any), or level of significance is not yet clear."

Translate that out of corporate-speak: Claude found something. Nobody knows what it does exactly. Nobody knows if it's useful, or even important.

Anthropic announced it anyway.

The thing itself turned up inside bacteriophages, the viruses that infect bacteria, sitting next to a repeating stretch of DNA that resembles a CRISPR array—the gene-editing tool that turned an obscure bacterial defense mechanism into a multi-billion-dollar medical industry. Anthropic named its find ART, short for array-associated reverse transcriptases.
