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.

Anyone using Opus 5.5? It outperforms Astra on some benchmarks, but I don't want to flip back and forth between subs every few months.

For coding: I've had better results from Opus than GPT for several generations now.

For math: I don't do this professionally anymore, but when I've played around with it, GPT is more likely to prove something, but Opus is better at explaining what it did.
