The models' case: Best overall for a typical new multimodal application: named dense and sparse vectors, native multivectors for ColPali/ColBERT, strong filtering, and flexible server-side. The models' main caveat: It is not a full search platform for teams needing sophisticated lexical analysis, joins, or elaborate non-vector ranking inside the engine. The strongest alternative is Vespa — Purpose-built for hybrid multimodal retrieval at scale — native tensor fields let you store and combine multiple embeddings (image, text, audio) per. Not unanimous: Claude picks Vespa.
