## What is it?

Swallow-code-v0.1 consists of 4 staged dataset subsets and are filtered from [bigcode/the-stack-v2-train-smol-ids](https://huggingface.co/datasets/bigcode/the-stack-v2-train-smol-ids).

## What is being released?

The dataset is released in four versions:
- **Swallow Code v0.1 stage 1**: 36B tokens, 41M documents containing Python scripts.
- **Swallow Code v0.1 stage 2**: 31B tokens, 37M documents containing Python scripts that are syntax error-free.
- **Swallow Code v0.1 stage 3**: 20B tokens, 24M documents containing Python scripts that are filtered with pylint score.
- **Swallow Code v0.1 stage 4**: 16B tokens, 21M documents containing Python scripts that are filtered with code comments and literal language detection(English and Japanese).

## Results and Performance

Llama-3.1-8B Performance after Continual Pretraining on 50B tokens Japanese, English, and Code(= swallow-code-v0.1) datasets.
