This is the official model release for the paper:

[**BiGR: Harnessing Binary Latent Codes for Image Generation and Improved Visual Representation Capabilities**]()  

Please download the pretrained weights for tokenizers and BiGR models to run our [code](https://github.com/haoosz/BiGR).

### Binary Autoencoder
We train Binary Autoencoder (B-AE) by adapting the [official code](https://github.com/ZeWang95/BinaryLatentDiffusion) of [Binary Latent Diffusion](https://arxiv.org/abs/2304.04820). We provide pretrained weights for different configurations.

**256x256 resolution**

### BiGR models ✨
We provide pretrained weights for BiGR models in various sizes.
