**RuCLIP** (**Ru**ssian **C**ontrastive **L**anguage–**I**mage **P**retraining) is a multimodal model 
for obtaining images and text similarities and rearranging captions and pictures. 
RuCLIP builds on a large body of work on zero-shot transfer, computer vision, natural language processing and 
multimodal learning. 

Model was trained by [Sber AI](https://github.com/sberbank-ai) and [SberDevices](https://sberdevices.ru/) teams.  
* Task: `text ranking`; `image ranking`; `zero-shot image classification`;
* Type: `encoder`
* Num Parameters: `150M`
* Training Data Volume: `240 million text-image pairs`
* Language: `Russian`
* Context Length: `77`
* Transformer Layers: `12`
* Transformer Width: `512`
* Transformer Heads: `8`
* Image Size: `224`
* Vision Layers: `12`
* Vision Width: `768`
* Vision Patch Size: `32`

## Usage [Github](https://github.com/sberbank-ai/ru-clip)

```
pip install ruclip
```

```python
clip, processor = ruclip.load("ruclip-vit-base-patch32-224", device="cuda")
```
