       | How does this work? I thought it was probably powered by
       | embeddings and maybe some more traditional search code, but I
       | checked out the linked github repo and I didn't see any
       | model/inference code. The public code is a wrapper that
       | communicates with your commercial API?
       | 
       | Some searches work like magic and others seem to veer off target
       | a lot. For example, "sculpture" and "watercolor" worked just
       | about how I'd expect. "Lamb" showed lambs and sheep. But "otter"
       | showed a random selection of animals.

         | It is powered by Mixedbread Search which is powered by our
         | model Omni. Omni is multimodal (text, video, audio, images) and
         | multi vector, which helps us to capture more information.
         | 
         | The search is in beta and we improving the model. Thank you for
         | reporting the queries which are not working well.
         | 
         | Edit: Re the otter, I just checked and I did not found otters
         | in the dataset. We should not return any results if the model
         | is not sure to reduce confusion.

           | neither "blue pictures" nor "multiples" worked well.

           | There's at least a little bit of otter in the data. The one
           | relevant result I saw was "Plate 40: Two Otters and a Beaver"
           | by Joris Hoefnagel.
           | 
           | I also expected semantic search to return similar results for
           | "fireworks" and "pyrotechnics," since the latter is a less
           | common synonym for the former. But I got many results for
           | fireworks and just one result for pyrotechnics.
           | 
           | This is still impressive. My impulse is to poke at it with
           | harder cases to try to reason about how it could be
           | implemented. Thanks for your Show HN and for replying to me!

             | If you find more such cases please feel free to send them
             | over to aamir at domain name of the Show HN. I would love
             | to see those cases and see how we can improve on them.
             | Thank you so much for the feedback.

       | hey, your service is back up again!!! Mixedbread was my favorite
       | tool for so long since your pivot, and I'm so glad y'all are back

         | We have a lot more things coming up soon. It just took us some
         | time building Mixedbread Search.

       | Colnomic and nvidia models are great for embedding images and
       | MUVERA can transform those to 1D vectors.

       | "Images of german shepherds" never fails to provide some humor.

           | The results for "Mark Rothko", "Paintings by Mark Rothko",
           | "Paintings similar to mark rothko" etc does not bring up
           | anything that I was expecting. NGA has a large collection of
           | Rothko paintings but none of them come up.
           | 
           | This NGA link returns over a thousand pieces by Rothko:

             | We are right now not including the artist name. Which will
             | be done in the next iteration of the model (next week).
             | Right now the search is only based on what the model can
             | "see". And it seems like that the model does not understand
             | the art of Mark Rothko.
             | 
             | The next version can see the image and read the metadata.
             | 
             | A bit more context: We are include everything in the latent
             | space (embeddings) without trying to maintain multiple
             | indexes and hack around things. There is still a huge
             | mountain to climb. But this one seems really promising.

       | This is neat, not sure how to report queries that are working
       | poorly as you have mentioned. But when I search "Waltz" I am
       | presented with Kitchen Utensils and only one piece of dancing
       | folks. Presumably this is due to the Artist's name being
       | 'Walton'.
