The Pile (pipeline)
EleutherAIThe original documented-corpus construction pipeline: downloads, combines, weights/upsamples, and formats 22 components into The Pile. Distinct from the released Pile dataset.
EleutherAI's the-pile construction code, distinct from the Pile dataset, and frozen since April 2023. It is the construction reference that underpinned GPT-Neo, GPT-J and Pythia. Verified 2026-08-13 via the GitHub README and the LICENSE body.

Adoption
2 medium confidence1,674 GitHub stars on EleutherAI/the-pile, read from the repository API, which bands at 1K-10K stars, level 2 on the stars fallback scale. That scale caps at level 3, because a star is not a use. The repo has been frozen since April 2023, but it is the canonical documented-corpus construction pipeline behind GPT-Neo, GPT-J and Pythia, so the level is directional.
