Model Details

Model Description

Vision Transformer (ViT) model trained on the largest dataset to-date for detecting AI-generated images in forensic applications.

• Developed by: Jeongsoo Park and Andrew Owens, University of Michigan
• Model type: Vision Transformer (ViT-Small)
• License: MIT (compatible with CreativeML OpenRAIL-M referenced in [2411.04125v1.pdf])
• Finetuned from: timm/vit_small_patch16_384.augreg_in21k_ft_in1k
• Adapted for HF inference compatibility by AI Without Borders.

HF Space will be open sourced shortly showcasing various ways to run ultra-fast inference. Make sure to follow us for updates, as we will be releasing a slew of projects in the coming weeks.
