+# OpenSDI-SD1.5-SigLIP2
+
+> OpenSDI-SD1.5-SigLIP2 is a vision-language encoder model fine-tuned from google/siglip2-base-patch16-224 for binary image classification. It is trained to detect whether an image is a real photograph or generated using Stable Diffusion 1.5 (SD1.5), utilizing the SiglipForImageClassification architecture.

+
+## Label Space: 2 Classes
+
+The model classifies an image as either:
+
+```
+Class 0: Real_Image
+Class 1: SD1.5_Generated
+```

+
+## Intended Use
+
+OpenSDI-SD1.5-SigLIP2 is designed for the following use cases:
+
+* Generative Model Evaluation – Detect SD1.5-generated images for analysis and benchmarking.
+* Dataset Integrity – Filter out AI-generated images from real-world image datasets.
+* Digital Media Forensics – Support visual content verification and source validation.
+* Trust & Safety – Detect synthetic media used in deceptive or misleading contexts.
