# RedPajama-Data-V2 1B

## Dataset Description
This is a **1.01 Billion token** subset of the [togethercomputer/RedPajama-Data-V2](https://huggingface.co/datasets/togethercomputer/RedPajama-Data-V2) dataset (specifically derived from the `sample-10B` config). It was created by randomly sampling the source data.

## Motivation
RedPajama V2 is a state-of-the-art web dataset with rich quality signals. This 1B token subset allows for rapid testing of these quality signals or other filtering experiments without needing to process the full multi-trillion token dataset.

## Dataset Details
- **Total Tokens:** 1,005,000,066 (~1.01B)
- **Source:** [togethercomputer/RedPajama-Data-V2](https://huggingface.co/datasets/togethercomputer/RedPajama-Data-V2) (config: `sample-10B`)
- **Structure:** Randomized slice of the source dataset.
- **Format:** Parquet (Snappy compression)
- **Producer:** Kris Bailey (kris@krisbailey.com)

## Usage

```python
from datasets import load_dataset

ds = load_dataset("krisbailey/RedPajama-Data-V2-1B", 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.

```python
# 100M Token Subset (approx 10%)
ds_100m = load_dataset("krisbailey/RedPajama-Data-V2-1B", split="train[:10%]")

# 500M Token Subset (approx 50%)
ds_500m = load_dataset("krisbailey/RedPajama-Data-V2-1B", split="train[:50%]")
```
