Not sure if it's fair to compare USearch and pgvector. One is an efficient indexing structure, the other is more like a pure database plugin. Not that they can't be used in a similar fashion.

If you are looking for pure indexing benchmarks, you might be interested in USearch vs FAISS HNSW implementation [1]. We run them ourselves (and a couple of other tech companies), so take them with a grain of salt. They might be biased.

As for Lantern vs pgvector, impressed by the result! A lot of people would benefit from having fast vector-search compatible with Postgres! The way to go!

It's wasn't a trivial integration by any means, and the Lantern team was very active - suggesting patches into the upstream version to ease integrations with other databases. Some of those are tricky and have yet to be merged [2]. So stay tuned for the USearch v3. Lots of new features coming :)
