# EvoLLM-v1-JP-7B

<!-- Provide a quick summary of what the model is/does. -->
EvoLLM-v1-JP-7B is a evolved Japanese Math LLM. 

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->
EvoLLM-v1-JP-7B is a Japanese Math LLM, merged the following source models in the Parameter Space (PS) by using an evolutionary approach.

## Usage

Use the code below to get started with the model.


```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer


# 1. load model
device = "cuda" if torch.cuda.is_available() else "CPU"
repo_id = "SakanaAI/EvoLLM-v1-JP-7B"
model = AutoModelForCausalLM.from_pretrained(repo_id, torch_dtype="auto")
tokenizer = AutoTokenizer.from_pretrained(repo_id)
model.to(device)

# 2. prepare inputs
template = """以下に、あるタスクを説明する指示があります。リクエストを適切に完了するための回答を日本語で記述してください。一歩一歩考えましょう。

### 指示:
{input}

### 応答:"""
text = "ミシュカは半ズボンを3本、長ズボンを3本、靴を3足買いました。半ズボンは1本$16.50でした。長ズボンは1本$22.50で、靴は1足$42でした。すべての衣類にいくら使いましたか？"
inputs = tokenizer(template.format(input=text), return_tensors="pt")

# 3. generate
output_ids = model.generate(**inputs.to(device))
output_ids = output_ids[:, inputs.input_ids.shape[1] :]
generated_text = tokenizer.batch_decode(output_ids, skip_special_tokens=True)[0]
print(generated_text)
```

## Evaluation

We present the results that compares the performance of the our evolved LLMs compared to the source LLMs. To reproduce the results, please use [our Github repository](https://github.com/SakanaAI/evolving-merged-models).
