# Dataset Card for TinyCorpus

<!-- Provide a quick summary of the dataset. -->

## Dataset Details

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->

- **Curated by:** Lucas S
- **Language(s) (NLP):** English
- **License:** apache-2.0

## Uses

<!-- Address questions around how the dataset is intended to be used. -->
This dataset comprises ~250B bytes of high quality text data. Should be used to train very small (<50M parameters) byte-level English models for educational purposes and to iterate on experimental LLM architectures quickly. 

## Dataset Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

The text is encoded in UTF-8 format, with \x02 (STX) and \x03 (ETX) as the start and end special bytes respectively. 

## Dataset Creation

### Curation Rationale

<!-- Motivation for the creation of this dataset. -->

There is a lack of modern pretraining mixtures for very small byte-level language models. 

### Source Data

<!-- This section describes the source data (e.g. news text and headlines, social media posts, translated sentences, ...). -->
