Mathematician Thomas Bloom reported that GPT 5.6 Pro, prompted by user DottedCalculator, has improved the bound on prime gaps by combining new sieving ideas with the established [FGKMT18] framework. The new bound saves a factor of approximately log3(n) compared to the previous record set in 2018. Furthermore, this result has been formally verified in Lean by Alexeev, highlighting the growing role of AI in advancing mathematical research.
