Researchers report factoring RSA-260 using autonomous software agents

Hacker News reports that Cognition used Devin agents to factor the 260-digit number.

The short version

  • Cognition researchers utilized Devin autonomous software agents to factor the 260-digit number RSA-260, establishing a new public challenge record.[Hacker News]
  • The achievement surpassed the previous RSA-250 benchmark set in February 2020.[Hacker News]
  • The computational effort relied on a GPU-adapted general number field sieve rather than quantum computing or manual trial.[Hacker News]
  • An estimated 4,900 GPU-days were consumed, while RSA-1024 factoring remains an expensive theoretical milestone.[Hacker News]

Key facts

  • The Cognition research team used Devin agents to factor RSA-260, setting a new public record.[Hacker News]
  • The prior public record was the factorization of RSA-250 achieved in February 2020.[Hacker News]
  • The project was completed through a GPU-oriented implementation of the general number field sieve.[Hacker News]
  • Computing costs were estimated at roughly 4,900 GPU-days, or approximately $400,000 at market rates.[Hacker News]

What remains uncertain

  • Whether frontier AI labs or hyperscalers can actually factor RSA-1024 at the projected cost of roughly $30 million per number remains an untested estimate.[Hacker News]
