Well now I know I have a bunch of software I want to try https://github.com/unum-cloud/. The author is definitely brilliant.
I should benchmark https://github.com/ashvardanian/SimSIMD/blob/main/include/si... and see if it's any faster than what hnswlib currently uses for bruteforce IP search because I'm currently using hnswlib in something and it's become a bottleneck. Or maybe I'll just try usearch directly.
