About

Swallow is the Tokyo Institute of Technology (tokyotech-llm) Japanese-focused LLM line built by continual pre-training of strong open bases, with instruction-tuned Instruct variants. Llama 3.1 Swallow (8B and 70B) continues Meta Llama 3.1 on a large Japanese web corpus plus Wikipedia, math, and code, then applies supervised fine-tuning on Japanese-oriented synthetic instruction data so Japanese ability rises while English capability is retained. The Swallow team publishes base and Instruct checkpoints across versions and documents the series on the Swallow project site and Hugging Face.
