Single-tenantMixpeek has no managed extractor for this model. On a single-tenant deployment you upload the weights and a custom plugin serves them next to the rest of your pipeline.
Overview
Jina Embeddings v5 Omni Small is a 2B-parameter embedding model that accepts text, images, audio, and video as input and produces 1024-dimensional vectors in a shared embedding space. This means you can index a video, then query it with text, an image, or an audio clip -- all vectors live in the same space.
The model aligns with jina-embeddings-v5-text, so text-only queries remain high quality. It supports Matryoshka representation learning, allowing you to truncate embeddings to smaller dimensions (512, 256) with graceful quality degradation.
Architecture
Based on a multimodal encoder with separate modality-specific preprocessors feeding into a shared transformer backbone. Supports Matryoshka dimensions (1024, 512, 256). Available in GGUF format for llama.cpp deployment.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so jina-embeddings-v5-omni-small runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.

// Managed alternative, if this exact model is not the requirement:
// image_extractor@v1 runs google/siglip-base-patch16-224
// (768-d) over a bucket, with no inference of your own.Capabilities
