# Web-SSL MAE ViT-3B: 2B MetaCLIP data, 224 Resolution
A 3 billion parameter Vision Transformer (ViT) trained with Masked Autoencoder (MAE) 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 (3072 width, 26 depth, 24 heads)
- **Parameters**: 3B
- **Resolution**: 224×224 pixels
- **Training**: Self-supervised Web-MAE on 2B image samples from MetaCLIP web data

## Model Descriptions
Web-SSL MAE 3B is a 3 billion parameter Vision Transformer model trained using masked autoencoder self-supervised learning on 2 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. Web-MAE exhibits particularly strong performance on OCR & Chart understanding tasks while maintaining competitive performance across traditional vision benchmarks and multimodal tasks.

## Usage
```python
from transformers import AutoImageProcessor, ViTModel
import torch
from PIL import Image

# Adjust the size, crop_size, etc. fields to your liking
processor = AutoImageProcessor.from_pretrained('facebook/webssl-mae3b-full2b-224')
model = ViTModel.from_pretrained('facebook/webssl-mae3b-full2b-224').cuda().eval()

# Process an image
image = Image.open('path/to/image.jpg')
inputs = processor(images=image, return_tensors="pt").to('cuda')
with torch.no_grad():
    outputs = model(**inputs)

# Extract features from the encoder
encoder_hidden_states = outputs.last_hidden_state
```
