deepfake-detector-model-v1

deepfake-detector-model-v1 is a vision-language encoder model fine-tuned from google/siglip-base-patch16-512 for binary deepfake image classification. It is trained to detect whether an image is real or generated using synthetic media techniques. The model uses the SiglipForImageClassification architecture.

Label Space: 2 Classes

The model classifies an image as one of the following:

Class 0: fake  
Class 1: real

Inference Code

from transformers import AutoImageProcessor, SiglipForImageClassification
from PIL import Image
import torch

# Load model and processor
model_name = "prithivMLmods/deepfake-detector-model-v1"  
model = SiglipForImageClassification.from_pretrained(model_name)
processor = AutoImageProcessor.from_pretrained(model_name)

# Updated label mapping
id2label = {
    "0": "fake",
    "1": "real"
}

    return prediction
