If you are just getting into this tech, like me, then this article leads down the rabbit hole of different index types supported in different vector stores. Most easy-to-use vector stores only use HNSW indices, which is "good enough".

A few offer different types of indices. Milvus[1] and FAISS[2] are a couple that support IVF indices. It's great to see another lightweight tool that does this with GPU acceleration.

Faiss is a library that supports indexing, not a fully-fledged vector database on its own. Milvus uses Faiss with a few other libraries to build a full vector database (https://github.com/milvus-io/milvus#acknowledgments).
