TinySwallow-1.5B-Instruct

Sakana and the Swallow team add Japanese instruction tuning to the Qwen-derived TinySwallow model. The release includes synthetic dialogue data associated with Gemma.

Research release

Read both the license section and intended-use statement

The license section permits commercial use when both sets of terms are met. A separate use section calls the model an experimental prototype and says commercial deployment is not intended. The catalog preserves both statements.TinySwallow-1.5B-Instruct official model card

Working with this release

Practical guidance. Apply the supplied chat template. Assess Japanese conversation quality separately from the memory savings offered by a particular weight format.

GGUF and MLC are packaging choices

Sakana publishes GGUF weights and a q4f32_1 MLC package for this instruction model. They are grouped here as formats rather than separate trained models.TinySwallow-1.5B-Instruct-GGUF official model cardTinySwallow-1.5B-Instruct-q4f32_1-MLC official model card
