Our Swallow model has undergone continual pre-training from the Llama 3 family, primarily with the addition of Japanese language data. The Instruct versions use supervised fine-tuning (SFT) and Chat Vector. Links to other models can be found in the index.
We are excited to share the release schedule for our latest models:

The following datasets were used for the instruction tuning.
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.
