Deepfake-Detect-Siglip2
Deepfake-Detect-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 detect whether an image is real or a deepfake using the SiglipForImageClassification architecture.
The model categorizes images into two classes:
- Class 0: "Fake" – The image is detected as a deepfake or manipulated.
- Class 1: "Real" – The image is classified as authentic and unaltered.

Intended Use:
The Deepfake-Detect-Siglip2 model is designed to distinguish between real and fake (deepfake) images. It is useful for identifying AI-generated or manipulated content.
Potential Use Cases:
- Deepfake Detection: Identifying AI-generated fake images.
- Content Verification: Assisting social media platforms in filtering manipulated content.
- Forensic Analysis: Supporting cybersecurity and investigative research on fake media.
- Media Authenticity Checks: Helping journalists and fact-checkers verify image credibility.
