Introduction

This is a text pre-training dataset used in the modality-aware continual pre-training of MoCa models. It is adapted from DCLM and randomly downsampled to ~20B tokens.

The dataset consists of text examples. text is a string containing text while images are left blank intentionally since there is no image available.
