## News
- 3/6/2025: :fire: Release **MegaPairs** ([repo](https://github.com/VectorSpaceLab/MegaPairs), [paper](https://arxiv.org/abs/2412.14475)), massive data synthesis for universal multimodal retrieval. And corresponding [BGE-VL](https://huggingface.co/collections/BAAI/megapairs-67c6bbe49c15a9e7a7c69d92) series multimodel embedding models!
- 3/6/2025: :fire::fire: Introduce **BGE-VL** ([HF repo](https://huggingface.co/collections/BAAI/megapairs-67c6bbe49c15a9e7a7c69d92)), State-Of-The-Art multimodal embedding models to support Any visual search applications (everything, including text-to-image, image-to-text, image&prompt-to-image, text-to-image&text, and more)! They are released under the MIT license and are completely free for both academic and commercial use. We also release **MegaPairs** ([repo](https://github.com/VectorSpaceLab/MegaPairs), [paper](https://arxiv.org/abs/2412.14475)), a massive synthetic dataset which empowers BGE-VL!
- 12/5/2024: :book: We built the [BGE documentation](https://www.bge-model.com) for centralized BGE information and materials!
- 10/29/2024: :earth_asia: We created WeChat group for BGE. Scan the [QR code](./imgs/BGE_WeChat_Group.png) to join the group chat! To get the first hand message about our updates and new release, or having any questions or ideas, join us now!
- <img src="./imgs/BGE_WeChat_Group.png" alt="bge_wechat_group" class="center" width="200">
- 10/22/2024: :fire: We release another interesting model: [OmniGen](https://github.com/VectorSpaceLab/OmniGen), which is a unified image generation model supporting various tasks. OmniGen can accomplish complex image generation tasks without the need for additional plugins like ControlNet, IP-Adapter, or auxiliary models such as pose detection and face detection.
- 9/10/2024: Introducing **MemoRAG**, a step forward towards RAG 2.0 on top of memory-inspired knowledge discovery (repo: https://github.com/qhjqhj00/MemoRAG, paper: https://arxiv.org/pdf/2409.05591v1) :fire:

- 9/2/2024: Start to maintain the [tutorials](./Tutorials/). The contents within will be actively updated and eariched, stay tuned! :books:
- 7/26/2024: Release a new embedding model [bge-en-icl](https://huggingface.co/BAAI/bge-en-icl), an embedding model that incorporates in-context learning capabilities, which, by providing task-relevant query-response examples, can encode semantically richer queries, further enhancing the semantic representation ability of the embeddings. :fire:
- 7/26/2024: Release a new embedding model [bge-multilingual-gemma2](https://huggingface.co/BAAI/bge-multilingual-gemma2), a multilingual embedding model based on gemma-2-9b, which supports multiple languages and diverse downstream tasks, achieving new SOTA on multilingual benchmarks (MIRACL, MTEB-fr, and MTEB-pl). :fire:

## Installation
### Using pip:
If you do not want to finetune the models, you can install the package without the finetune dependency:
