Yes I had a look at it, I haven't tried e5-mistral-7b-instruct yet but I'll definitely give it a go.
Is there such a leaderboard only focused on retrieval by any chance? I haven't found one so far
It's interesting how the massive model of e5-mistral has only marginal performance gains over the bge-base and similar ones. It could still be useful for the longer sentence length though.
