HNSW is popular but has major drawbacks, like high memory use and complex updates. Disk-based solutions like IVF, especially with RabitQ, offer better scalability and efficiency. It's time to consider simpler alternatives! #VectorDatabases #HNSW #IVF blog.pgvecto.rs/why-hnsw-is-no…

> First, we’re introducing explicit functions that treat external object storage locations as first-class data citizens. Second, we’re integrating the ability to run LLMs directly within the Postgres platform. Interview with my senior coworker, Torsten. odbms.org/2024/10/on-edb…

@mattshumer_ I ended up writing it out myself using @modal_labs for getting embeddings, and @qdrant_engine for vectors, then realised I need lots of filtering and switched to pgvecto.rs

TIL about binary vector search... apparently there's a trick where you can take an embedding vector like [0.0051, 0.017, -0.0186, -0.0185...] and turn that into a binary vector just reflecting if each value is > 0 - so [1, 1, -1, -1, ...] and still get useful cosine similarities!

It is important to note that this is closely tied to the embedding model being used. The benchmark we conducted specifically focused on OpenAI's text-embedding-3-large model. Maybe some binary embedding models have better performance. e.g. @cohere @JinaAI_
