# Comma v0.1 dataset

This repository contains the dataset used to train [Comma v0.1-1T](https://huggingface.co/common-pile/comma-v0.1-1t) and [Comma v0.1-2T](https://huggingface.co/common-pile/comma-v0.1-2t).
It is a slightly modified and consolidated version of the [Common Pile v0.1 "filtered" data](https://huggingface.co/collections/common-pile/common-pile-v01-filtered-data-68300bb0a946d10dda697663).
If you are looknig for the raw Common Pile v0.1 data, please see [this collection](https://huggingface.co/collections/common-pile/common-pile-v01-raw-data-6826b454a5a6a445d0b51b37).
You can learn more about Common Pile in [our paper](https://huggingface.co/papers/2506.05209).

## Mixing rates and token counts

The Comma v0.1 models were trained in two stages, a "main" stage and a "cooldown" stage.
During each stage, we heuristically set mixing rates to up or downweight different sources.
In the two tables below, we provide per-source token count, repeat rate, and effective token count (after up/downweighting) for the main and cooldown stage of the Comma v0.1-1T training run.
For the Comma v0.1-2T training run, all sources are repeated 2x as many times in both stages.
Token counts are as provided by the Comma v0.1 tokenizer; using a different tokenizer may change these counts significantly.
