# KARAKURI LM

![KARAKURI LM](./thumbnail.png)

KARAKURI LM is a pretrained language model that builds upon Llama 2.
Our model enhances Llama 2's capabilities by incorporating additional Japanese vocabulary and further pretraining on a mixture of Japanese and multilingual corpora.

KARAKURI LM Chat is a fine-tuned version of KARAKURI LM, which was trained on a mixture of publicly available and closed datasets using the [SteerLM](https://aclanthology.org/2023.findings-emnlp.754/) technique.
During fine-tuning, our model employed a continual learning approach.
Unlike the common practice of relying solely on structured conversational datasets, we also incorporated unstructured corpora, similar to what was used during its pretraining phase.

Despite the conversational datasets containing only 2.5% Japanese tokens, our model has shown remarkable performance.
It achieves the highest performance among Japanese open models on the [MT-Bench-jp](https://api.wandb.ai/links/wandb-japan/6ff86bp3) at the time of release.
Furthermore, it achieves performance comparable to Llama 2 70B Chat on the original English [MT-Bench](https://huggingface.co/spaces/lmsys/mt-bench).

You can find more details in our blog post ([en](https://medium.com/karakuri/introducing-karakuri-lm-34c79a3bf341), [ja](https://medium.com/karakuri/karakuri-lm%E3%81%AE%E8%A7%A3%E8%AA%AC-4b6cf9c3d40f)).

| Swallow-70B-Instruct                |   70B   |     SFT     |        4.39 |

It also achieves performance comparable to Llama 2 70B Chat on the original English [MT-Bench](https://huggingface.co/spaces/lmsys/mt-bench):

| Model                         |  Average | MT-Bench | MT-Bench-jp |
| :---------------------------- | -------: | -------: | ----------: |
| **KARAKURI LM 70B Chat v0.1** | **6.52** | **6.61** |    **6.43** |
| Llama 2 70B Chat              |     6.04 |     6.86 |        5.23 |

## Use in 🤗 Transformers

You can run the model using the `pipeline()` function from 🤗 Transformers:

```python
from transformers import pipeline

generator = pipeline("text-generation", model="karakuri-ai/karakuri-lm-70b-v0.1", device_map="auto", torch_dtype="auto")

prompt = """以下は人間とAIアシスタントとの会話です。

Human: こんにちは。
AI: こんにちは、私はAIアシスタントです。何かお手伝いできることはありますか？
Human: 週末に日帰りで東京に遊びに行こうと思っています。日帰りなので、短時間で回れるおすすめの観光プランを教えてください。
AI: """
outputs = generator(prompt, return_full_text=False, max_new_tokens=512)
outputs[0]["generated_text"]
```
