Claude lifts Riemann zero bound to 67%—AI narrows hypothesis gap
Claude, Anthropic’s latest model, raised the proven lower bound for zeta‑function zeros on the critical line from 41.6% to 67.2%. The result builds on decades of number‑theory work and was vetted by specialists, showing AI can meaningfully advance hard mathematics—even if a full proof of the Riemann hypothesis remains out of reach.
