Technologisma

The technologisma is an unnoticeable 7-limit comma measuring about 0.012 cents, or 1/98278.5 of an octave. Tempering it out gives the technologismic temperament, a very high accuracy 7-limit rank-3 temperament that can be defined by 46edo, 51edo and 130edo, and is the difference between the slendrisma and the schisma.

Trivia

It was named by Praveen Venkataramana and Tristan Bay in 2024. The name was chosen arbitrarily, but a mildly interesting fact is that if A=1, B=2, ... up to Z=26, "ChatGPT" adds up to 75, which is also the sum of the absolute values of the monzo entries of the chatgptsma (51 + 13 + 1 + 10). The name has received a considerable amount of negative feedback in the xenharmonic community, which may lead to an eventual name change in the future.
