# DALL·E Mini

_Generate images from a text prompt_

<img src="https://github.com/borisdayma/dalle-mini/raw/main/img/logo.png" width="200">

Our logo was generated with DALL·E mini using the prompt "logo of an armchair in the shape of an avocado".

You can create your own pictures with [the demo](https://huggingface.co/spaces/flax-community/dalle-mini).

## How does it work?

Refer to [our report](https://wandb.ai/dalle-mini/dalle-mini/reports/DALL-E-mini--Vmlldzo4NjIxODA).

## Inference Pipeline

To generate sample predictions and understand the inference pipeline step by step, refer to [`tools/inference/inference_pipeline.ipynb`](tools/inference/inference_pipeline.ipynb).

## Contributing

Join the community on the [DALLE-Pytorch Discord](https://discord.gg/xBPBXfcFHd).
Any contribution is welcome, from reporting issues to proposing fixes/improvements or testing the model with cool prompts!

## Development

### Dependencies Installation

For inference only, use `pip install git+https://github.com/borisdayma/dalle-mini.git`.

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

### Image Encoder

We use a VQGAN from [taming-transformers](https://github.com/CompVis/taming-transformers), which can also be fine-tuned.

Use [patil-suraj/vqgan-jax](https://github.com/patil-suraj/vqgan-jax) if you want to convert a checkpoint to JAX (does not support Gumbel).

Any image encoder that turns an image into a fixed sequence of tokens can be used.

### Training of DALL·E mini

Use [`tools/train/train.py`](tools/train/train.py).

You can also adjust the [sweep configuration file](https://docs.wandb.ai/guides/sweeps) if you need to perform a hyperparameter search.

## FAQ

### Where to find the latest models?

Trained models are on 🤗 Model Hub:

- [VQGAN-f16-16384](https://huggingface.co/dalle-mini/vqgan_imagenet_f16_16384) for encoding/decoding images
- [DALL·E mini](https://huggingface.co/flax-community/dalle-mini) 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 to us.
