The “equivalent” here would be Jina-Clip (architecture-wise), not necessarily performance.

The ColPali paper(1) does a good job explaining why you don’t really want to directly use vision embeddings; and how you are much better off optimizing for RAG with a ColPali like setup. Basically, it is not optimized for textual understanding, it works if you are searching for the word bird; and images of birds. But doesn’t work well to pull a document where it’s a paper about birds.

Makes sense. My main takeaway from the ColPali paper (and your comments) is that ColPali works best for document RAG, whereas vision model embeddings are best used for image similarity search or sentiment analysis. So to answer my own question: The best model to use depends on the application.
