Md Ismail Šojal 🕷️(@0x0SojalSec):For thirty years the number field sieve was the bottleneck. 🙌 a legendary C implementation, put it on GPUs, and keep 2,048 chips working for ten days. Anthropic engineer Steve Weis factored RSA-896 (896 bits, 270 digits) with Claude’s help porting CADO-NFS and orchestrating that fleet. About 30 GPU-years of work. That is the actual shock.
