AI-vs-Deepfake-vs-Real-Siglip2

AI-vs-Deepfake-vs-Real-Siglip2 is an image classification vision-language encoder model fine-tuned from google/siglip2-base-patch16-224 for a single-label classification task. It is designed to distinguish AI-generated images, deepfake images, and real images using the SiglipForImageClassification architecture.

The model categorizes images into three classes:

• Class 0: "AI" – The image is fully AI-generated, created by machine learning models.
• Class 1: "Deepfake" – The image is a manipulated deepfake, where real content has been altered.
• Class 2: "Real" – The image is an authentic, unaltered photograph.

Intended Use:

The AI-vs-Deepfake-vs-Real-Siglip2 model is designed to classify images into three categories: AI-generated, deepfake, or real. It helps in identifying whether an image is fully synthetic, altered through deepfake techniques, or an unaltered real image.

Potential Use Cases:

• Deepfake Detection: Identifying manipulated deepfake content in media.
• AI-Generated Image Identification: Distinguishing AI-generated images from real or deepfake images.
• Content Verification: Supporting fact-checking and digital forensics in assessing image authenticity.
• Social Media and News Filtering: Helping platforms flag AI-generated or deepfake content.
