Are these dedicated vector databases doing anything more complicated than what can be accomplished using Postgres with the Cube extension?

- m00x 3y agoYou don't need a dedicated vector db, you can use pgvector. You could maybe use Cube for euclidean space search, but you're better off using optimized algorithms for embedding space search. https://github.com/pgvector/pgvector https://github.com/pgvector/pgvector
- gk1 3y agoYes, see: https://www.pinecone.io/blog/hnsw-not-enough/ https://www.pinecone.io/blog/hnsw-not-enough/
- ok123456 3y agoThis is an unconvincing advertisement.
