**Mirage-Test** is a modern **test-only dataset** for benchmarking AI-generated image detection models. 
It contains **real** (`0_real`) and **fake** (`1_fake`) images across five distinct content domains, designed to evaluate generalization across diverse visual semantics. 
The fake images are generated using state-of-the-art generative models specifically optimized for perceptual realism and visual fidelity.

> 📌 **This dataset is for evaluation only. No training split is provided.**

## 📁 Dataset Structure

Images are organized hierarchically by content type and authenticity:

```bash
Mirage-Test/
├── Animal/
│ ├── 0_real/ # Real animal photos
│ └── 1_fake/ # AI-generated animal images
├── Anime/
│ └── 1_fake/ # AI-generated anime-style images
├── Human/
│ ├── 0_real/ # Real human photos
│ └── 1_fake/ # AI-generated human images
├── Object/
│ ├── 0_real/ # Real object photos
│ └── 1_fake/ # AI-generated object images
├── Scene/
│ ├── 0_real/ # Real landscape/architecture photos
│ └── 1_fake/ # AI-generated scenes images
├── metadata.parquet
└── README.md
```

- **Total samples**: 49000
