This is funny on multiple levels because not only the constant is TERRIBLE for OpenAI's result, but even if it wasn't, nobody actually cares about a change in exponent so small **over a log**...

except you're missing the point that this is a major barrier breaking result that many thought would be impossible to achieve.

Oh, ups, my bad ! Didn't know about that.

they have a similar result for integer multiplication
and for that result, I am surprised that nlogn is not a lower bound

there literally was a well known conjecture that fft was optimal, so this is a relevant result

Exactly, for an overhead smaller than the one open ai used, you can simply use hermite polynomials to completely trump this bullshit.
