Anthropic said its AI model Claude autonomously discovered a previously uncharacterized enzyme system in bacteriophages, similar to the machinery behind Crispr. The discovery came after nearly 950 Claude agents processed 210 million tokens over 21 hours. The company announced the finding as it prepares to go public and expand into drug discovery.

Key Facts

Anthropic's Claude AI discovered a new enzyme system in bacteriophages after analyzing 210 million tokens over 21 hours.
Nearly 950 Claude agents participated in the search, with one flagging an unusual repeating pattern for human review.
The enzyme system's function remains unknown, and Anthropic said it shared the findings early to demonstrate Claude's capabilities.
Anthropic is expanding its wet lab into drug discovery and recruiting more scientists as it prepares to go public.

The Discovery

Anthropic said Claude found the enzyme system after searching through a massive database of DNA sequences. Scientists' involvement was limited to the initial prompt and lab work, according to the company. Over 21 hours, nearly 950 Claude agents worked through 210 million tokens before one spotted an unusual repeating pattern. Further analysis and lab testing revealed a previously uncharacterized enzyme system found in bacteriophages, viruses that infect bacteria.

Company Context

Anthropic said it is still working to understand what the enzyme system does. The company felt it was important to share such findings early to demonstrate Claude's capabilities and give the broader community insight into its work. The announcement comes as Anthropic seeks to attract more scientists to its lab and expand into areas like drug discovery. Anthropic is preparing to go public, and the push into scientific research is part of a broader AI industry trend.
