I tried TQ for vector search and my findings is not good, it is not worth it if you cannot use GPU, however I got same quality of search as 32f using 8bit quant

I wrote ann ext for sqlite, using tq, I do save a lot on space but 32f is still faster despite everything I have tried

code here https://github.com/netdur/munind/tree/main/src/tq

you’re right that 32f is faster on raw query time, quantization adds extra step. main benefit on download size since gzip won’t help much, which matters most in browser contexts

So i assumed it would get crushed by OPQ (which requires training)
