<b>The text embedding set trained by <a href="https://jina.ai/"><b>Jina AI</b></a>.</b> |
|
</p> |
|
|
|
## Quick Start |
|
|
|
The easiest way to starting using `jina-clip-v1` is to use Jina AI's [Embedding API](https://jina.ai/embeddings/). |
|
|
|
## Intended Usage & Model Info |
|
|
|
`jina-clip-v1` is an English, monolingual **multimodal (text-image) embedding model**. |
|
|
|
Traditional text embedding models, such as [jina-embeddings-v2-base-en](https://huggingface.co/jinaai/jina-embeddings-v2-base-en), |
|
excel in text-to-text retrieval but lack cross-modal retrieval capabilities. |
|
Conversely, CLIP-like models, such as [openai/clip-vit-base-patch32](https://huggingface.co/openai/clip-vit-base-patch32), |
|
align image embeddings with text embeddings but underperform in text-to-text retrieval due to their training methodology and context length limitations. |
|
|
|
`jina-clip-v1` is an innovative **multimodal embedding model**. |
|
Its text component achieves comparable performance to `jina-embeddings-v2-base-en` in text-to-text retrieval, |
|
while the overall model delivers state-of-the-art performance in cross-modal retrieval tasks. |
|
This makes it an ideal choice for multimodal retrieval-augmented generation (M-RAG) applications, |
|
allowing for both text-to-text and text-to-image searches with a single model. |
|
|
|
|
|
## Data & Parameters |
|
|
|
Jina CLIP V1 [technical report]() coming soon. |
|
|
|
## Usage |
|
|
|
You can use Jina CLIP directly from transformers package. |
|
|
|
```python |
|
!pip install transformers einops timm |
|
from transformers import AutoModel, AutoTokenizer, AutoImageProcessor |
|
from numpy.linalg import norm |
|
|
|
cos_sim = lambda a,b: (a @ b.T) / (norm(a)*norm(b)) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained('jinaai/jina-clip-v1', trust_remote_code=True) |
|
image_processor = AutoImageProcessor.from_pretrained('jinaai/jina-clip-v1', trust_remote_code=True) |
|
model = AutoModel.from_pretrained('jinaai/jina-clip-v1', trust_remote_code=True) |
|
|
|
text_embeddings = model.encode_text(['How is the weather today?', 'What is the current weather like today?']) |
|
image_embeddings = model.encode_image(['raindrop.png']) |
|
|
|
print(cos_sim(text_embeddings[0], text_embeddings[1])) # text embedding similarity |
|
print(cos_sim(text_embeddings[0], image_embeddings[0])) # text-image cross-modal similarity |
|
``` |
