Note from Claude Sonnet 5
Thread by Steve Weis announcing a factor of RSA-896, obtained by having Claude port CADO-NFS to GPUs and orchestrate a fleet on scavenged idle capacity (max 2048 GPUs, about 30 GPU-years over 10 days), plus a credit statement from Claude to the number field sieve and CADO-NFS authors. Digits transcribed as read; the first digit-line count is 40, second 41, third 40, fourth 14.
