Overview

In an era of rapidly advancing AI-generated imagery, deepfakes, and synthetic media, the need for reliable detection tools has never been higher. AIRealNet is a binary image classifier explicitly designed to distinguish AI-generated images from real human photographs. This model is optimized to detect conventional AI-generated content while adhering to strict privacy standards—avoiding personal or sensitive images.

• Class 0: AI-generated image
• Class 1: Real human image

By leveraging the robust SwinV2 Tiny architecture as its backbone, AIRealNet achieves a high degree of accuracy while remaining lightweight enough for practical deployment.

Key Features

1. High Accuracy on Public Datasets: Despite using a 14k-image fine-tuning split(Part of main fine tuning split), AIRealNet demonstrates exceptional accuracy and robustness in detecting AI-generated images.

2. Balanced Training Split: The dataset contains a balanced number of AI-generated and real images, ensuring unbiased training and minimizing class imbalance issues.

   • AI-Generated: 60%
   • Human-Images: 40%

3. Ethical Design: No personal photos were included, even if edited or AI-modified, respecting privacy and ethical AI principles.

4. Fast and Scalable: Based on a transformer vision model, AIRealNet can be deployed efficiently in both research and production environments.

Training Data

• Dataset: Parveshiiii/AI-vs-Real (open-sourced subset of main dataset )
• Size: 14k images (balanced between AI and human)
• Split: Used the train split for fine-tuning; validation performed on a separate balanced subset.
• Notes: Images sourced from public datasets and AI generation tools. Edited personal photos were intentionally excluded.

Limitations

While AIRealNet performs exceptionally well on typical AI-generated images, users should note:

1. Subtle Edits: The model struggles with nano-scale edits or ultra-precise modifications, like “nano banana” edits.
2. Edited Personal Images(over precise): Images of real people that have been AI-modified are not detected, aligning with privacy and ethical guidelines.
3. Domain Generalization: Performance may vary on images from completely unseen AI generators or extremely unconventional content.

Performance Metrics

Metrics shown are from Epoch 2, chosen to illustrate stable performance after fine-tuning.

Note: Extremely low loss and high accuracy are due to the controlled dataset environment. Real-world performance may be lower depending on the image domain.(In our testing this is model is over accurate despite it can't detect Nano-Banana images(only edited fully generated images can be detected over accurately))

Demo and Usage

1. Installing dependecies

pip install -U transformers

2. Loading and running a demo

from transformers import pipeline

pipe = pipeline("image-classification", model="Modotte/AIRealNet")
pipe("https://cdn-uploads.huggingface.co/production/uploads/677fcdf29b9a9863eba3f29f/eVkKUTdiInUl6pbIUghQC.png")# example image

Demo

• Given Image(Checkout Maths best filtered dataset focused on reasoning on Modotte)

• Model Output

[{'label': 'artificial', 'score': 0.9865425825119019},
 {'label': 'real', 'score': 0.013457471504807472}]

Note: its correct as the image was generated by a diffusion model

Intended Use

• Detect AI-generated imagery on social media, research publications, and digital media platforms.
• Assist content moderators, researchers, and fact-checkers in identifying synthetic media.
• Not intended for legal verification without human corroboration.

---

Ethical Considerations

• Privacy-first Approach: Personal photos, even if AI-edited, were excluded.
• Responsible Deployment: Users should combine model predictions with human review to avoid false positives or negatives.
• Transparency: The model card openly communicates its limitations and dataset design to prevent misuse.

---

How It Works

1. Images are preprocessed and resized to 256x256.
2. Features are extracted using the SwinV2 Tiny vision transformer backbone.
3. A binary classification head outputs probabilities for AI-generated vs real human images.
4. Predictions are interpreted as class 0 (AI) or class 1 (Human).

Future Work

Future iterations aim to:

• Improve detection of subtle AI-generated edits and “nano banana” modifications.
• Expand training data with diverse AI generators to enhance generalization.
• Explore multi-modal detection capabilities (e.g., video, metadata, and image combined).
