What options do you think work better?

I’m trying build an exhaustive list of realistic options. See the spreadsheet here

I don’t have an opinion, just wondering why they didn’t choose other another option such as Sentence Embeddings, OpenAI embeddings, etc.

FAISS can be used with OpenAI embeddings (and any other embedding model).

FAISS is technology for fast indexed similarity vector search - using it is an independent decision from which model you use to create those vectors.
