An Unreleased Claude Improved a Longstanding Bound on the Riemann Hypothesis, and Terence Tao Warns About the Cost

Anthropic reports the model raised the proven fraction of zeta zeros satisfying the hypothesis from 41.6 percent to 67.2 percent, as the Fields Medalist argues faster output may come at the price of training fewer mathematicians.

Anthropic says an unreleased research version of Claude improved a longstanding lower bound related to the Riemann hypothesis, raising the proven fraction of non-trivial zeros of the Riemann zeta function that lie on the critical line from…
