DALL·E Mini

How to use it?

You can use the model on 🖍️ craiyon

How does it work?

Refer to our reports:

• DALL·E mini - Generate Images from Any Text Prompt
• DALL·E mini - Explained
• DALL·E mega - Training Journal

Development

Dependencies Installation

For inference only, use pip install dalle-mini.

For development, clone the repo and use pip install -e ".[dev]". Before making a PR, check style with make style.

You can experiment with the pipeline step by step through our inference pipeline notebook

Training of DALL·E mini

Use tools/train/train.py.

You can also adjust the sweep configuration file if you need to perform a hyperparameter search.

FAQ

Where to find the latest models?

Trained models are on 🤗 Model Hub:

• VQGAN-f16-16384 for encoding/decoding images
• DALL·E mini or DALL·E mega for generating images from a text prompt

Where does the logo come from?

The "armchair in the shape of an avocado" was used by OpenAI when releasing DALL·E to illustrate the model's capabilities. Having successful predictions on this prompt represents a big milestone for us.

Contributing

Join the community on the LAION Discord. Any contribution is welcome, from reporting issues to proposing fixes/improvements or testing the model with cool prompts!

You can also use these great projects from the community:
