# Tiny GenImage Dataset

## 📝 Dataset Description

### Dataset Summary

The Tiny GenImage Dataset is a curated, scaled-down collection of images and associated metadata designed to train, validate, and benchmark models for detecting and identifying artificially generated content. The dataset contains a mix of real-world images alongside those generated by prominent AI models, including various diffusion models (like Stable Diffusion 1.4/1.5, GLIDE, Midjourney, ADM, VQDM, Wukong) and GANs (BigGAN).

Each image is labeled under two categories, enabling researchers and developers to tackle two distinct, high-value computer vision tasks: binary real/fake classification and multi-class source model identification.

### Supported Tasks and Leaderboards

This dataset directly supports two critical image classification tasks:

|**Task ID**|**Task Name**|**Description**|**Output Classes**|
|---|---|---|---|
|**Task A**|Binary Veracity Classification|Classifying images as either real or fake.|2 (real, fake)|
|**Task B**|AI Model Source Identification|Identifying the specific AI generation model used for images labeled as AI-Generated.|9 (Real, ADM, BigGAN, GLIDE, Midjourney, SD14, SD15, VQDM, Wukong)|

### Languages

The descriptive text, including all class labels and metadata, is in English (en).

## 🗂️ Data Splits

The dataset is divided into training and validation splits to facilitate standard machine learning workflows.

|**Split**|**Number of Instances**|**Notes**|
|---|---|---|
|**train**|28,000|Used for model training and weight optimization.|
|**validation**|7,000|Used for hyperparameter tuning and intermediate model evaluation.|

## 💾 Dataset Structure

### Data Instances

A single data instance consists of an image file and two distinct labels detailing its source and authenticity.

|**Field Name**|**Example Value**|**Description**|
|---|---|---|
|**image**|`<PIL.Image.Image object>`|The actual image content loaded into a PIL object.|
|**label**|`1`|Binary label for authenticity (Real vs. AI-Generated).|
|**generator**|`4`|Multi-class label for the specific generation model (or Real).|

### Data Fields

The dataset contains the following fields:

|**Field Name**|**Data Type**|**Description**|
|---|---|---|
|**image**|`datasets.Image()`|The actual image content (e.g., .jpg, .png).|
|**label**|`datasets.ClassLabel`|Task A: Binary label for image veracity.|
|**generator**|`datasets.ClassLabel`|Task B: Label specifying the generation source/model.|

## 🏷️ Label Definitions

The two label fields use the following strict mappings:

**`label` (Binary Veracity Classification)**

|**Label**|**Value**|**Description**|
|---|---|---|
|**real**|`0`|Image is a real photograph/non-AI generated.|
|**fake**|`1`|Image was created by an AI generation model.|

**`generator` (Model Source Identification)**

|**Label**|**Value**|**Description**|
|---|---|---|
|**Real**|`0`|Real image (no AI generation involved).|
|**ADM**|`1`|Generated by Ablated Diffusion Model (Guided Diffusion).|
|**BigGAN**|`2`|Generated by BigGAN.|
|**GLIDE**|`3`|Generated by GLIDE.|
|**Midjourney**|`4`|Generated by Midjourney.|
|**SD14**|`5`|Generated by Stable Diffusion 1.4.|
|**SD15**|`6`|Generated by Stable Diffusion 1.5.|
|**VQDM**|`7`|Generated by Vector Quantized Diffusion Model.|
|**Wukong**|`8`|Generated by the Wukong diffusion model.|
