Llama 3.1 Swallow - Built with Llama

Llama 3.1 Swallow is a series of large language models (8B, 70B) that were built by continual pre-training on the Meta Llama 3.1 models. Llama 3.1 Swallow enhanced the Japanese language capabilities of the original Llama 3.1 while retaining the English language capabilities. We use approximately 200 billion tokens that were sampled from a large Japanese web corpus (Swallow Corpus Version 2), Japanese and English Wikipedia articles, and mathematical and coding contents, etc for continual pre-training. The instruction-tuned models (Instruct) were built by supervised fine-tuning (SFT) on the synthetic data specially built for Japanese (see the Training Datasets section for details). See the Swallow Model Index section to find other model variants.

Training Datasets

Continual Pre-Training

The following datasets were used for continual pre-training.

Swallow Corpus Version 2

We built the Swallow Corpus by extracting high-quality Japanese texts from Common Crawl. In Version 2, we expanded the scope of the Common Crawl collection and modified the pipeline sequence to enable more flexible quality filtering. For Llama 3.1 Swallow v0.2, we further refined our quality filtering and data sampling strategies, resulting in an even higher-quality selection of Japanese texts for pre-training.

Further details of the methodology and analysis will be provided in a forthcoming paper.

The-stack-v2(filtered)

We created a high-quality Python code corpus, The-Stack-v2(filtered), by applying filtering to The-Stack-v2-train-smol-ids. This filtering process utilizes Python's compile() function, pylint, and language detection on comments within the code to select only data that meets a certain quality threshold. Further details will be available in our forthcoming paper.

Risks and Limitations

The models released here are still in the early stages of our research and development and have not been tuned to ensure outputs align with human intent and safety considerations.
