Sorry a noob question, how is Faiss different from say pgvector, other than the fact that pgvector is developed mainly as a postgres plugin? I think I saw use cases of using pgvector for similarity search on openai encoidings of text (which itself is generated from a NN)

Scale, Faiss supports a bunch more algorithms. A much larger scale.

Thank you, that makes sense

Although there is some work going on right now to add support for the type of algorithms in pgvector to alot it to scale better (and also to have better recall/speed tradeoffs).
