This repository contains the official checkpoint for PixelGPT, as presented in the paper [Autoregressive Pre-Training on Pixels and Texts (EMNLP 2024)](https://arxiv.org/pdf/2404.10710). For detailed instructions on how to use the model, please visit our [GitHub page](https://github.com/ernie-research/pixelgpt/).

## Model Description
PixelGPT is an autoregressive language model pre-trained exclusively on pixel data using a next patch prediction objective. By processing documents as visual data (pixels), the model learns to predict the next image patch in a sequence, enabling it to handle visually complex tasks without relying on tokenized text. This tokenization-free approach allows PixelGPT to process and understand text rendered as images.
