Has anyone successfully used embeddings with anything other than OpenAI's APIs? I've seen lots of debates on using embeddings vs fine-tuning for things like chatbots on private data, but is there a reason why you can't use both? IE, fine-tune LLaMA on your data, then run the same embeddings approach on top of your own fine-tuned model?
