Jina Embeddings v5 Omni Nano
Omni Nano accepts text, images, video and audio, including supported document inputs. It uses approximately 1.04 billion parameters and keeps its text vectors aligned with Jina Embeddings v5 Text Nano.
How the model works
The model returns 768-dimensional embeddings with an 8,192-token sequence limit. Retrieval, classification, clustering and text matching have their own adapters. Its model card documents query and document roles for retrieval, including media input. On Nano, this role mainly changes the text side; image embeddings vary less.Jina Embeddings v5 Omni Nano model details
Use and access
Jina distributes the complete adapter package and separate merged task variants. Elastic Inference Service and the Jina API provide managed access, while weights permit local use under CC BY-NC 4.0. The smaller vector width also changes storage requirements relative to Omni Small. The two sizes use different text spaces and should not be mixed in one index without validation.Jina Embeddings v5 Omni Nano model detailsJina Embeddings v5 Omni Nano technical overview
