<b>Jina CLIP v2: Multilingual Multimodal Embeddings for Texts and Images</b>
</p>


## Quick Start

[Blog]() | [Azure](https://azuremarketplace.microsoft.com/en-gb/marketplace/apps/jinaai.jina-clip-v2-vm?tab=Overview) | [AWS SageMaker](https://aws.amazon.com/marketplace/pp/prodview-bfbctuqmky676) | [Google Cloud Platform](https://console.cloud.google.com/marketplace/browse?hl=en&inv=1&invt=AbiD-g&q=jina) | [API](https://jina.ai/embeddings)


## Intended Usage & Model Info

`jina-clip-v2` is a state-of-the-art **multilingual and multimodal (text-image) embedding model**. It is a successor to the [`jina-clip-v1`](https://huggingface.co/jinaai/jina-clip-v1) model and brings new features and capabilities, such as:

* *support for multiple languages* - the text tower is trained on 89 languages with tuning focus on *Arabic, Bengali, Chinese, Danish, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Indonesian, Italian, Japanese, Korean, Latvian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian, Urdu,* and *Vietnamese.*
* *embedding truncation on both image and text vectors* - both towers are trained using [Matryoshka Representation Learning](https://arxiv.org/abs/2205.13147) which enables slicing the output vectors and consequently computation and storage costs.
* *visual document retrieval performance gains* - with an image resolution of 512 (compared to 224 on `jina-clip-v1`) the image tower can now capture finer visual details. This feature along with a more diverse training set enable the model to perform much better on visual document retrieval tasks. Due to this `jina-clip-v2` can be used as an image encoder in vLLM retriever architectures.

Similar to our predecessor model, `jina-clip-v2` bridges the gap between text-to-text and cross-modal retrieval. Via a single vector space, `jina-clip-v2` offers state-of-the-art performance on both tasks.
This dual capability makes it an excellent tool for multimodal retrieval-augmented generation (MuRAG) applications, enabling seamless text-to-text and text-to-image searches within a single model.


## Data & Parameters

[Check out our paper](https://arxiv.org/abs/2405.20204). Updated technical report for v2 coming soon!


## Usage

1. The easiest way to start using jina-clip-v2 is via Jina AI's [Embeddings API](https://jina.ai/embeddings/).
2. Alternatively, you can use the model directly via the transformers/sentence-transformers package.

```python
# !pip install transformers einops timm pillow
from transformers import AutoModel

# Initialize the model
model = AutoModel.from_pretrained("jinaai/jina-clip-v2", trust_remote_code=True)

# Corpus
sentences = [
    "طاهٍ يطبخ المعكرونة في المطبخ", # Arabic
    "厨师在厨房煮意大利面", # Chinese
    "Un chef qui cuisine des pâtes dans la cuisine", # French
    "Ein Koch, der in der Küche Pasta kocht", # German
    "Ένας σεφ μαγειρεύει ζυμαρικά στην κουζίνα", # Greek
    "एक शेफ रसोई में पास्ता पका रहा है", # Hindi
    "Uno chef che cucina la pasta in cucina", # Italian
    "シェフがキッチンでパスタを作っている", # Japanese
    "셰프가 주방에서 파스타를 요리하고 있다", # Korean
]


# Public image URLs or Pil
image_urls = ["https://i.ibb.co/bRGGJxD/DALL-E-2024-11-20-13-44-46-A-highly-realistic-8-K-photographic-image-of-a-chef-cooking-pasta-in-a-mo.webp"]
# Choose a matryoshka dimension, set to None to get the full 1024-dim vectors
truncate_dim = 512

# Encode text and images
text_embeddings = model.encode_text(sentences, truncate_dim=truncate_dim)
image_embeddings = model.encode_image(
    image_urls, truncate_dim=truncate_dim
)  # also accepts PIL.image, local filenames, dataURI

# Encode query text
query = "A chef cooking pasta in the kitchen" # English
query_embeddings = model.encode_text(
    query, task="retrieval.query", truncate_dim=truncate_dim
)

# text to image
print("En -> Img: " + str(query_embeddings @ image_embeddings[0].T))
# text to text
print("En -> Ar: " + str(query_embeddings @ text_embeddings[0].T))
print("En -> Zh: " + str(query_embeddings @ text_embeddings[1].T))
print("En -> Fr: " + str(query_embeddings @ text_embeddings[2].T))
print("En -> De: " + str(query_embeddings @ text_embeddings[3].T))
print("En -> Gr: " + str(query_embeddings @ text_embeddings[4].T))
print("En -> Hi: " + str(query_embeddings @ text_embeddings[5].T))
print("En -> It: " + str(query_embeddings @ text_embeddings[6].T))
print("En -> Jp: " + str(query_embeddings @ text_embeddings[7].T))
print("En -> Ko: " + str(query_embeddings @ text_embeddings[8].T))
```

or via sentence-transformers:

```python
# !pip install sentence-transformers einops timm pillow
from sentence_transformers import SentenceTransformer

# Initialize the model
truncate_dim = 512
model = SentenceTransformer(
    "jinaai/jina-clip-v2", trust_remote_code=True, truncate_dim=truncate_dim
)

# Corpus
sentences = [
    "طاهٍ يطبخ المعكرونة في المطبخ", # Arabic
    "厨师在厨房煮意大利面", # Chinese
    "Un chef qui cuisine des pâtes dans la cuisine", # French
    "Ein Koch, der in der Küche Pasta kocht", # German
    "Ένας σεφ μαγειρεύει ζυμαρικά στην κουζίνα", # Greek
    "एक शेफ रसोई में पास्ता पका रहा है", # Hindi
    "Uno chef che cucina la pasta in cucina", # Italian
    "シェフがキッチンでパスタを作っている", # Japanese
    "셰프가 주방에서 파스타를 요리하고 있다", # Korean
]

# Public image URLs or Pil
image_urls = ["https://i.ibb.co/bRGGJxD/DALL-E-2024-11-20-13-44-46-A-highly-realistic-8-K-photographic-image-of-a-chef-cooking-pasta-in-a-mo.webp"]

text_embeddings = model.encode(sentences)
image_embeddings = model.encode(image_urls)
query = "A chef cooking pasta in the kitchen" # English
query_embeddings = model.encode(query)
```
