You're absolutely right—sqlite-vec currently only supports brute-force search, and its latency does scale linearly with dataset size. We did some rough comparisons using its benchmark tools: on the SIFT dataset, latency was around 100ms; on GIST, it was closer to 1000ms. In contrast, with zvec's HNSW implementation, we get ~1ms latency on SIFT and ~3ms on GIST, while achieving recall@100 of 99.9% on SIFT and 97.7% on GIST.

FWIW "You're absolutely right" broadly declares "a human is not piloting the keyboard"
You are undoubtedly correct!
