siglip2-x256-explicit-content

siglip2-x256-explicit-content 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.

Label Space: 5 Classes

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"

Intended Use

This model is intended for applications such as:

• Content Moderation: Automatically detect NSFW or suggestive content.
• Parental Controls: Enable AI-based filtering for safe media browsing.
• Dataset Preprocessing: Clean and categorize image datasets for research or deployment.
• Online Platforms: Help enforce content guidelines for uploads and user-generated media.
