Project mention: DocArray – Represent, send, and store multimodal data for ML | news.ycombinator.com | 2023-04-27
Project mention: [D]: Best nearest neighbour search for high dimensions | /r/MachineLearning | 2023-05-17I'll assume this is the link to pynndescent, looks cool! Thanks for sharing. I haven't used it before. Also seems like it's an approximate nearest neighbor algorithm, just FYI for others seeing this.
Why do you use pgvector instead of pgANN? My understanding is pgANN is built with FAISS. When I compared pgvector with FAISS, pgvector was 3-5x slower.

Project mention: Created a smol vector database in my free time. Looking to provide a LangChain integration soon! | /r/LangChain | 2023-05-06It supports all the basic features like creating an index, inserting vectors and searching through them. Here's the GitHub link if anyone's interested in going over it: https://github.com/0xDebabrata/citrus
