Falcon RefinedWeb 1B

Dataset Description

This is a 1.01 Billion token subset of the tiiuae/falcon-refinedweb dataset. It was created by streaming the dataset with a large shuffle buffer to ensure a random, representative sample of the web data.

Motivation

RefinedWeb is a high-quality filtered web dataset, but the full version is massive. This 1B token slice provides a perfect testbed for evaluating model architecture changes or for use in curriculum learning experiments.

Dataset Details

• Total Tokens: 1,005,000,041 (~1.01B)
• Source: tiiuae/falcon-refinedweb
• Method: Streamed with shuffle buffer (size=5000).
• Format: Parquet (Snappy compression)
• Producer: Kris Bailey (kris@krisbailey.com)

Usage

from datasets import load_dataset

ds = load_dataset("krisbailey/falcon-refinedweb-1B", split="train")
print(ds[0])

Subsets & Slicing

Since this dataset was randomly shuffled during creation, you can safely slice it to get smaller, representative datasets (e.g., for scaling laws experiments) without needing to download the full dataset.

# 100M Token Subset (approx 10%)
ds_100m = load_dataset("krisbailey/falcon-refinedweb-1B", split="train[:10%]")

# 500M Token Subset (approx 50%)
ds_500m = load_dataset("krisbailey/falcon-refinedweb-1B", split="train[:50%]")
