Training Data

Training data shapes what a model learns. We build and document open corpora so researchers can inspect that foundation and study how changing it changes a model.

The Pile brought together diverse sources of text in an 800GB language-modeling dataset. The Common Pile extends our work on open training data with an 8TB collection of public domain and openly licensed text.

Releasing a corpus also means documenting where its contents came from and how they were selected. This connects dataset construction to research on filtering, licensing, and the effects of data composition.
