Ops-MM-embedding-v1-7B
Ops-MM-embedding-v1-7B is a dense, large-scale multimodal embedding model developed and open-sourced by the Alibaba Cloud OpenSearch-AI team, fine-tuned from Qwen2-VL.
Key Features
Unified Multimodal Embeddings
- Encodes text, images, text-image pairs, visual documents, and videos (by treating video frames as multiple image inputs) into a unified embedding space for cross-modal retrieval.
High Performance on MMEB
- Achieves SOTA results among models of similar scale on MMEB-V2 and MMEB-Image benchmark (until 2025-07-03).
Multilingual Capabilities
- Ops-MM-embedding-v1-7B achieves SOTA performance among dense models on the ViDoRe-v2 benchmark, demonstrating strong cross-lingual generalization.
Training data
MMEB-train, CC-3M, colpali training set.
