       | There's the interesting question here - has embedding performance

       | 100 candidates and reranking the results. Does it really matter
       | if a model is 1 - 3% better on pulling in the top 10 when it's
       | probably going to be captured in the top 50? I think at this
       | point the real frontier is making these models as small as
       | possible to minimize hosting costs.

         | (1-3) results in a search. If you can get the most relevant
         | result from position, let's say 7 to 2, that can have a big
         | impact on the user experience. And I know they market this for
         | RAG, but I think that's just marketing and this is as relevant
         | for traditional search.

       | So, based on the emphasis on "retrieval" in the blog title, are
       | these models narrowly focused on retrieval tasks only? E.g. I
       | shouldn't use them for clustering, STS, and so on?
       | 
       | How does voyage-3.5 compare against Gemini Embedding (GE)? I
       | thought GE had top spot for retrieval tasks on MMTEB. Is Voyage
       | saying here that voyage-3.5 now has the top spot? Or is it just
       | that, for the 10 specified datasets, voyage-3.5 outperforms the
       | specified OpenAI and Cohere models.
