There was an open source vector database that was suppose to be an alternative to pinecone that was mentioned a few weeks back.

I can’t seem to find it. Does anyone recall the name?

Not sure which one, but if you are after a vector search engine (not just a database) then I can recommend this https://github.com/marqo-ai/marqo. Includes inference, transformations, schema's, multi-modal search, multi-modal queries, multi-modal representations, text chunking and more.
