Dataset Details
Dataset Description
- Curated by: Lucas S
- Language(s) (NLP): English
- License: apache-2.0
Uses
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
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
There is a lack of modern pretraining mixtures for very small byte-level language models.
