webssl-dino300m-full2b-224

A 300 million 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" (Fan et al., 2025).

Model Details

• Architecture: ViT (1536 width, 40 depth, 24 heads)
• Parameters: 300M
• Resolution: 224×224 pixels
• Training: Self-supervised Web-DINO on 2B image samples from MetaCLIP web data

Model Descriptions

Web-SSL DINO 300M is a 300 million parameter Vision Transformer model trained using 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.

Usage

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

processor = AutoImageProcessor.from_pretrained('facebook/webssl-dino300m-full2b-224')
model = Dinov2Model.from_pretrained('facebook/webssl-dino300m-full2b-224')

# 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
