How does this compare to duckdbs vector capabilities (vss extension)?

Yes, nothing on that or sqlite-vec (both of which seem to be apples to apples comparisons).

I maintain a fork of sqlite-vec (because there hasn't been activity on the main repo for more than a year): sqlite-vec is great for smaller dimensionality or smaller cardinality datasets, but know that it's brute-force, and query latency scales exactly linearly. You only avoid full table scans if you add filterable columns to your vec0 table and include them in your WHERE clause. There's no probabilistic lookup algorithm in sqlite-vec.

You're right that we didn't include sqlite-vec in our initial benchmarks—apples-to-apples comparisons are always better. I've actually added basic zvec tests to my fork of sqlite-vec (https://github.com/luoxiaojian/sqlite-vec), so feel free to give it a try. We'll also be publishing a more complete performance comparison in an upcoming blog post—stay tuned!
