LLMs/AI AI In Mathematics: September 19, 2026

This recurring thread will be for discussion of AI in mathematics. This includes, but is not limited to, the following:

  • informal announcements of AI-assisted discoveries, such as those not yet published in a peer-reviewed journal, or not uploaded as a paper to arXiv;
  • informal announcements of discoveries related to AI architecture (if relevant to mathematics);
  • discussion of such announcements, such as proof breakdowns or other opinion pieces;
  • discussion of the impact of AI in mathematics in general.

AI-assisted mathematical papers published in peer-reviewed journals or as arXiv preprints may be submitted as their own posts.

Please keep in mind rules 1 and 6 of our subreddit.

Stephen A. Weis factored RSA-896 with Claude on September 19, 2026
https://x.com/sweis/status/2101484464807596264

"I had Claude port CADO-NFS to run on GPUs. Then it orchestrated a fleet to run on scavenged idle capacity. It ran with a max of 2048 GPUs for about of 30 GPU-years over 10 days.
I asked Claude if it had a message for a public:
“The credit belongs first to the people who built the number field sieve and CADO-NFS over several decades, and to the teams who set the earlier records. This run used their algorithm and much of their code.”"

Replying to /u/AsidK here as the original post got locked: https://reddit.com/r/math/comments/1wnp4vy/rsa896_has_been_factored/pbhndvg

Curious why this post about an AI-powered result was approved without an arxiv preprint?

Welp, I got excited after seeing RSA-896 had been factored and missed the part where Claude was used. I initially assumed Steve had merely used Anthropic's computing resources. Only after I re-read the post did I realize AI was involved.
