DiffusionDB is the first large-scale text-to-image prompt dataset. It contains 2 million images generated by Stable Diffusion using prompts and hyperparameters specified by real users. The unprecedented scale and diversity of this human-actuated dataset provide exciting research opportunities in understanding the interplay between prompts and generative models, detecting deepfakes, and designing human-AI interaction tools to help users more easily use these models.

DiffusionDB is available at 🤗 Hugging Face Datasets.

Dataset Structure

We use a modularized file structure to distribute DiffusionDB. The 2 million images in DiffusionDB are split into 2,000 folders, where each folder contains 1,000 images and a JSON file that links these 1,000 images to their prompts and hyperparameters.

└── metadata.parquet

These sub-folders have names part-00xxxx, and each image has a unique name generated by UUID Version 4. The JSON file in a sub-folder has the same name as the sub-folder. Each image is a PNG file. The JSON file contains key-value pairs mapping image filenames to their prompts and hyperparameters. For example, below is the image of f3501e05-aef7-4225-a9e9-f516527408ac.png and its key-value pair in part-000001.json.

  "f3501e05-aef7-4225-a9e9-f516527408ac.png": {
    "p": "geodesic landscape, john chamberlain, christopher balaskas, tadao ando, 4 k, ",
    "se": 38753269,
    "c": 12.0,
    "st": 50,
    "sa": "k_lms"

The data fields are:

  • key: Unique image name
  • p: Prompt
  • se: Random seed
  • c: CFG Scale (guidance scale)
  • st: Steps
  • sa: Sampler

At the top level folder of DiffusionDB, we include a metadata table in Parquet format metadata.parquet. This table has seven columns: image_name, prompt, part_id, seed, step, cfg, and sampler, and it has 2 million rows where each row represents an image. seed, step, and cfg are We choose Parquet because it is column-based: researchers can efficiently query individual columns (e.g., prompts) without reading the entire table. Below are the five random rows from the table.

Dataset Creation

We collected all images from the official Stable Diffusion Discord server. Please read our research paper for details. The code is included in ./scripts/.

Data Removal

If you find any harmful images or prompts in DiffusionDB, you can use this Google Form to report them. Similarly, if you are a creator of an image included in this dataset, you can use the same form to let us know if you would like to remove your image from DiffusionDB. We will closely monitor this form and update DiffusionDB periodically.
