dolma

Dolma is two things:

1. Dolma Dataset: an open dataset of 3 trillion tokens from a diverse mix of web content, academic publications, code, books, and encyclopedic materials.
2. Dolma Toolkit: a high-performance toolkit for curating datasets for language modeling -- this repo contains the source code for the Dolma Toolkit.

Dolma Dataset

Dolma is an open dataset of 3 trillion tokens from a diverse mix of web content, academic publications, code, books, and encyclopedic materials. It was created as a training corpus for OLMo, a language model from the Allen Institute for AI (AI2).

Dolma is available for download on the HuggingFace 🤗 Hub: huggingface.co/datasets/allenai/dolma. Dolma is licensed under ODC-BY; see our blog post for explanation.

You can also read more about Dolma in our announcement, as well as by consulting its data sheet.

Dolma Toolkit

This repository houses the Dolma Toolkit, which enables curation of large datasets for (pre)-training ML models. Its key features are:

1. High Performance ⚡: Can process billions of documents concurrently thanks to built-in parallelism.
2. Portability 🧳: Works on a single machine, a cluster, or cloud environment.
3. Built-In Taggers 🏷: Includes ready-to-use taggers commonly used to curate datasets such as Gopher, C4, and OpenWebText.
4. Fast Deduplication 🗑: Speedy document deduplication using a Rust Bloom filter.
5. Extensibility 🧩 & Cloud Support ☁: Supports custom taggers and AWS S3-compatible locations.

To install, simply type pip install dolma in your terminal.

To learn more about how to use the Dolma Toolkit, please visit the documentation.
