What is everyone using embeddings for, and which mdels? I built a RAG last year (for searching long documents) but found it a bit disappointing. I tested it with OpenAI and with SentenceTransformers (instructor-xl or a smaller variant). Apparently they've come a long way since then though. Currently I'm working on an old fashioned search engine (tf-if + keyword expansion). Apparently that can work better than vector databases in some cases: https://news.ycombinator.com/item?id=38703943 https://news.ycombinator.com/item?id=38703943
