## Hugging Face models
The UniDisc checkpoints are available on Hugging Face:
* [Interleaved Image-Text](https://huggingface.co/aswerdlow/unidisc_interleaved)
* [Non-Interleaved (Static)](https://huggingface.co/aswerdlow/unidisc_non_interleaved)
## Getting Started
Code can be found here: https://github.com/alexanderswerdlow/unidisc/tree/main
To install the dependencies, run:
```bash
git submodule update --init --recursive
uv sync --no-group dev
uv sync
```
For a more detailed installation guide, please refer to [INSTALL.md](docs/INSTALL.md).
## Data
See [DATA.md](docs/DATA.md) for details on how to download and preprocess the datasets. We provide processing scripts and instructions for all of the used datasets. Additionally, we release a synthetic dataset available [here](https://huggingface.co/datasets/aswerdlow/unidisc_hq) and the corresponding [generation scripts](unidisc/datasets/preprocessing/unidisc_dataset/README.md) as well as the raw data.
## Training
See [TRAIN.md](docs/TRAIN.md) for training commands.
