GPT-6 Astra claims first improvement on prime gaps since the 1930s, shaving a log log n factor
rapha_gl · x · 2026-09-04
Announced as part of the GPT-6 Astra launch, the model reportedly improved the bound on the longest gap between primes by roughly a log log n factor — the first improvement of that size since the 1930s.
Context from the thread: prior progress by subsets of Ford, Green, Konyagin, Maynard and Tao, and more recently by GPT 5.6 Sol, were smaller log log log n factors. If verified, it would mark another landmark AI-for-math result.
