# Web-SSL DINO ViT-7B: 8B MetaCLIP data, 518 Resolution

A 7 billion parameter Vision Transformer (ViT) trained with DINOv2 self-supervised learning on web-scale image data without language supervision. Introduced in ["Scaling Language-Free Visual Representation Learning"](https://arxiv.org/abs/2504.01017) (Fan et al., 2025).

## Model Details
- **Architecture**: ViT (4096 width, 32 depth, 32 heads)
- **Parameters**: 7B
- **Resolution**: 518×518 pixels
- **Training**: Self-supervised Web-DINO on 8B image samples from MetaCLIP web data

## Model Descriptions
Web-SSL DINO 7B is a 7 billion parameter Vision Transformer model trained using self-supervised learning on 8 billion web images without language supervision. This model demonstrates that pure visual learning, when scaled appropriately, can match or exceed the performance of language-supervised models like CLIP across various vision tasks. It excels in both traditional vision benchmarks and multimodal tasks including visual question answering and OCR & chart understanding.

## Usage

```python
from transformers import AutoImageProcessor, Dinov2Model
import torch
from PIL import Image

processor = AutoImageProcessor.from_pretrained('facebook/webssl-dino7b-full8b-518')
model = Dinov2Model.from_pretrained('facebook/webssl-dino7b-full8b-518')

# Process an image
image = Image.open('path/to/image.jpg')
inputs = processor(images=image, return_tensors="pt")
with torch.no_grad():
    outputs = model(**inputs)
cls_features = outputs.last_hidden_state[:, 0]  # CLS token features
patch_features = outputs.last_hidden_state[:, 1:] # patch-wise token features
```
