More so, I am wondering how it is that Pinecone manages to land on the HN front page so frequently given the large number of alternatives (see all the other comments in this thread). It suggests to me a coordinated marketing effort (brigading, cronyism, etc.)
Oh man, now I sound like I'm part of the brigading :) FWIW I recently evaluated pinecone and alternatives and decided not go with pinecone (pgvector).

Having myself recently bootstrapped an understanding of language models et al, I would not be surprised if the pinecone learning center gets a lot of traffic.
