NEWAnthropic Claude Cracks RSA-896 in 10 Days to Set New Factoring Record

Anthropic's Claude AI model employed 2,048 GPUs to break the RSA-896 encryption key. The process took 10 days and established a new public factoring record, following jumps from 829 to 862 bits in the previous 16 days. This sequence represents an acceleration in AI-assisted factorization of large prime numbers used in cryptography.

Cognition's Devin model cracked RSA-260 two weeks ago using $400,000 of Nvidia B200 GPUs. RSA encryption serves as the underlying security layer for banking systems and various digital communication protocols across the financial sector.
