Jina Embeddings v5 Omni Small
Omni Small maps several media types into the vector space of Jina Embeddings v5 Text Small. The approximately 1.74-billion-parameter model can add media queries to an index built with its matching text model.
How the model works
The release combines a text backbone with visual and audio encoders. It produces 1,024-dimensional vectors and supports a 32,768-token sequence. Four adapters cover retrieval, classification, clustering and text matching. The base package retains all adapters; merged task packages select one of them.Jina Embeddings v5 Omni Small model details
Use and access
For retrieval, the model distinguishes queries from documents across media types. Jina documents encode_query and encode_document methods rather than an undifferentiated encode call. Weights and managed API access are offered. The matching Text Small model supplies the compatible text space; compatibility should not be assumed for Text Nano or an unrelated embedding model.Jina Embeddings v5 Omni Small model detailsJina Embeddings v5 Omni Small technical overview
