#1 multimodal embedding model: unified text, image, screenshot, and video retrieval
Qwen/Qwen3-VL-Embedding-8Bmixpeek://text_extractor@v1/qwen3_vl_embed_8b_v1Overview
Qwen3-VL-Embedding-8B is a unified multimodal embedding model that projects text, images, screenshots, and video into a shared vector space. It achieves state-of-the-art results on MMEB-V2 (77.9 overall), the most comprehensive multimodal retrieval benchmark, and scores 83.3 on visual document retrieval, making it the strongest general-purpose multimodal embedding available.
Built on the Qwen3-VL vision-language backbone, it supports Matryoshka flexible dimensionality (64 to 4096), 32K context windows, and 30+ languages. On Mixpeek, it powers cross-modal retrieval where a text query can match images, screenshots, video frames, or documents in a single vector search pass.
Architecture
Qwen3-VL vision-language backbone (8B parameters) with shared projection heads for text, image, and video modalities. Uses Matryoshka Representation Learning for flexible embedding dimensions from 64 to 4096. Supports interleaved text-image input sequences up to 32K tokens.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so Qwen3-VL-Embedding-8B 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.
