Claude Helps Set Elliptic Curve Rank Records of 30 and 31

The gist

The previous step in this sequence, from rank 28 to rank 29, took more than 18 years; the jump to ranks 30 and 31 occurred within days using AI assistance. The result demonstrates a potentially useful AI-assisted research capability in number theory.

The full picture

Anthropic mathematician Levent Alpöge and cryptographer Ava Howell used an internal, non-public variant of Claude to discover elliptic curves with ranks of at least 30 and 31, surpassing a record that had previously advanced to rank 29 only after more than 18 years. The new examples emerged within days from a relatively simple prompt to the model. Both researchers have extensive background knowledge in elliptic curve research. Higher-rank elliptic curves are more mathematically complex, with rank determining how certain points are distributed along the curve.
