Libraries

How to use SakanaAI/TinySwallow-1.5B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="SakanaAI/TinySwallow-1.5B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("SakanaAI/TinySwallow-1.5B")
model = AutoModelForCausalLM.from_pretrained("SakanaAI/TinySwallow-1.5B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

TinySwallow-1.5B

🤗 Models | 📚 Paper | 📝 Blog | 🐦 Twitter

TinySwallow-1.5B is a Japanese compact language model created through TAID (Temporally Adaptive Interpolated Distillation), our new knowledge distillation method. We used Qwen2.5-32B-Instruct as the teacher model and Qwen2.5-1.5B-Instruct as the student model. The model has been further pre-trained on Japanese text data to enhance its Japanese language capabilities.

If you are looking for an instruction-following model, check TinySwallow-1.5B-Instruct.
