SigLIP2-ImageShield-90M-256

SigLIP2-ImageShield-90M-256 is a vision-language encoder model fine-tuned from google/siglip2-base-patch16-256 for multi-class image classification. Built on the SiglipForImageClassification architecture, the model is designed to identify and categorize visual content for explicit, suggestive, and safe media filtering.

SigLIP 2: Multilingual Vision-Language Encoders with Improved Semantic Understanding, Localization, and Dense Features https://arxiv.org/pdf/2502.14786

Label Space: 5 Classes

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

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

Install Dependencies

pip install transformers torch torchvision pillow gradio

Intended Use

This model is intended for applications such as:

• Content Moderation: Detect explicit or suggestive visual content.
• Parental Controls: Support AI-based media filtering.
• Dataset Preprocessing: Categorize and filter image datasets.
• Online Platforms: Assist with content safety and upload moderation.
