# Model Card for AI Image Classification - Midjourney V6 & SDXL  

## Model Details  

### Model Description  

This model is a **Swin Transformer-based classifier** designed to distinguish between **AI-generated** and **human-created** images, specifically focusing on outputs from **Midjourney V6** and **Stable Diffusion XL (SDXL)**. It has been trained on a curated dataset of AI-generated images.  

- **Developed by:** Deepankar Sharma  
- **Model type:** Image Classification (Swin Transformer)  
- **Finetuned from model:** SwinForImageClassification  

### Model Sources  

- **Repository:** [Hugging Face Model Repository](https://huggingface.co/ideepankarsharma2003/AI_ImageClassification_MidjourneyV6_SDXL)  

## Uses  

### Direct Use  

This model can be used for **detecting AI-generated images** from Midjourney V6 and SDXL. It is useful for content moderation, fact-checking, and detecting synthetic media.  

### Out-of-Scope Use  

- The model is **not designed** for detecting AI-generated images from all generative models.  
- It **may not perform well** on heavily edited AI-generated images or images mixed with human elements.  
- It is **not intended for forensic-level deepfake detection**.  

## Bias, Risks, and Limitations  

This model is trained specifically on **Midjourney V6** and **Stable Diffusion XL** datasets. It may not generalize well to images generated by other AI models. Additionally, biases in the dataset could lead to **false positives** (flagging real images as AI-generated) or **false negatives** (failing to detect AI-generated content).  

### Recommendations  

Users should verify results with additional tools and **not solely rely on this model** for high-stakes decisions. Model performance should be tested on domain-specific datasets before deployment.  

## How to Get Started with the Model  

You can use this model with the 🤗 Transformers library:  

```python
from transformers import AutoModelForImageClassification, AutoFeatureExtractor
from PIL import Image
import torch

# Load model and feature extractor
model_name = "ideepankarsharma2003/AI_ImageClassification_MidjourneyV6_SDXL"
model = AutoModelForImageClassification.from_pretrained(model_name)
feature_extractor = AutoFeatureExtractor.from_pretrained(model_name)

# Load and preprocess image
image = Image.open("path_to_image.jpg")
inputs = feature_extractor(images=image, return_tensors="pt")

# Perform inference
with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_label = logits.argmax(-1).item()

# Label Mapping
id2label = {0: "ai_gen", 1: "human"}
print("Predicted label:", id2label[predicted_label])
```
