deepfake-detector-model-v1

(★ 18)

deepfake-detector-model-v1 is a vision-language encoder model fine-tuned from siglip2-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
```

---

## Install Dependencies

```bash
pip install -q transformers torch pillow gradio hf_xet
```

---

## Inference Code

```python
import gradio as gr
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"
}

def classify_image(image):
    image = Image.fromarray(image).convert("RGB")
    inputs = processor(images=image, return_tensors="pt")

with torch.no_grad():
        outputs = model(**inputs)
        logits = outputs.logits
        probs = torch.nn.functional.softmax(logits, dim=1).squeeze().tolist()

prediction = {
        id2label[str(i)]: round(probs[i], 3) for i in range(len(probs))
    }

return prediction

# Gradio Interface
iface = gr.Interface(
    fn=classify_image,
    inputs=gr.Image(type="numpy"),
    outputs=gr.Label(num_top_classes=2, label="Deepfake Classification"),
    title="deepfake-detector-model",
    description="Upload an image to classify whether it is real or fake using a deepfake detection model."
)

if __name__ == "__main__":
    iface.launch()
```

## Intended Use

`deepfake-detector-model` is designed for:

* **Deepfake Detection** – Accurately identify fake images generated by AI.
* **Media Authentication** – Verify the authenticity of digital visual content.
* **Content Moderation** – Assist in filtering synthetic media in online platforms.
* **Forensic Analysis** – Support digital forensics by detecting manipulated visual data.
* **Security Applications** – Integrate into surveillance systems for authenticity verification.
