nsfw-image-detection

nsfw-image-detection is a vision-language encoder model fine-tuned from siglip2-base-patch16-256 for multi-class image classification. Built on the SiglipForImageClassification architecture, the model is trained to identify and categorize content types in images, especially for explicit, suggestive, or safe media filtering.

Demo Inference

The model classifies each image into one of the following content categories:

Class 0: "Anime Picture"  
Class 1: "Hentai"  
Class 2: "Normal"  
Class 3: "Pornography"  
Class 4: "Enticing or Sensual"
