Web-SSL MAE ViT-H (700M): 2B MetaCLIP data, 224 Resolution

A 700 million parameter Vision Transformer (ViT-H) trained with Masked Autoencoder (MAE) 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-H (Huge)
• Parameters: 700M
• Resolution: 224×224 pixels
• Training: Self-supervised Web-MAE on 2B image samples from MetaCLIP web data

Model Descriptions

Web-SSL MAE ViT-H is a 700 million 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

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-mae700m-full2b-224')
model = ViTModel.from_pretrained('facebook/webssl-mae700m-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
