+
+### Model Description
+
+**Llama-3-ELYZA-JP-8B** is a large language model trained by [ELYZA, Inc](https://elyza.ai/). 
+Based on [meta-llama/Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct), it has been enhanced for Japanese usage through additional pre-training and instruction tuning. (Built with Meta Llama3)
+
+For more details, please refer to [our blog post](https://note.com/elyza/n/n360b6084fdbd).
+
+### Usage
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+DEFAULT_SYSTEM_PROMPT = "あなたは誠実で優秀な日本人のアシスタントです。特に指示が無い場合は、常に日本語で回答してください。"
+text = "仕事の熱意を取り戻すためのアイデアを5つ挙げてください。"
+
+model_name = "elyza/Llama-3-ELYZA-JP-8B"
+
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = AutoModelForCausalLM.from_pretrained(
+    model_name,
+    torch_dtype="auto",
+    device_map="auto",
+)
+model.eval()
+
+messages = [
+    {"role": "system", "content": DEFAULT_SYSTEM_PROMPT},
+    {"role": "user", "content": text},
+]
+prompt = tokenizer.apply_chat_template(
+    messages,
+    tokenize=False,
+    add_generation_prompt=True
+)
+token_ids = tokenizer.encode(
+    prompt, add_special_tokens=False, return_tensors="pt"
+)
+
+with torch.no_grad():
+    output_ids = model.generate(
+        token_ids.to(model.device),
+        max_new_tokens=1200,
+        do_sample=True,
+        temperature=0.6,
+        top_p=0.9,
+    )
+output = tokenizer.decode(
+    output_ids.tolist()[0][token_ids.size(1):], skip_special_tokens=True
+)
+print(output)
