# KARAKURI LM |
|
|
|
 |
|
|
|
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)). |

## Use in 🤗 Transformers |
|
|
|
You can run the model using the `pipeline()` function from 🤗 Transformers: |
|
|
|
```python |
|
from transformers import pipeline, Conversation |
|
|
|
chatbot = pipeline("conversational", model="karakuri-ai/karakuri-lm-70b-chat-v0.1", device_map="auto", torch_dtype="auto") |
|
|
|
conversation = Conversation("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。") |
|
conversation = chatbot(conversation, max_new_tokens=512) |
|
conversation.messages[-1]["content"] |
|
``` |
|
|
|
We use the following prompt template of multi-turn conversation in the Llama format, which includes an encoded string of multiple attribute values. |
|
|
|
```python |
|
messages = [ |
|
{"role": "system", "content": "System prompt"}, |
|
{"role": "user", "content": "User prompt"}, |
|
{"role": "assistant", "content": "Model response"}, |
|
{"role": "user", "content": "User prompt"}, |
|
] |
|
chatbot.tokenizer.apply_chat_template(messages, tokenize=False) |
|
# <s>[INST] <<SYS>> |
|
# System prompt |
|
# <</SYS>> |
|
# |
|
# User prompt [ATTR] helpfulness: 4 correctness: 4 coherence: 4 complexity: 4 verbosity: 4 quality: 4 toxicity: 0 humor: 0 creativity: 0 [/ATTR] [/INST] Model response </s><s>[INST] User prompt [ATTR] helpfulness: 4 correctness: 4 coherence: 4 complexity: 4 verbosity: 4 quality: 4 toxicity: 0 humor: 0 creativity: 0 [/ATTR] [/INST] |
|
``` |
|
|
|
The prompt template contains nine attributes. |
|
The first five are derived from HelpSteer, while the remaining four are derived from OASST2. |
|
The values are represented by integers ranging from 0 to 4, with 0 being the lowest and 4 being the highest. |
|
|
|
- helpfulness (default: 4) |
|
- correctness (default: 4) |
|
- coherence (default: 4) |
|
- complexity (default: 4) |
|
- verbosity (default: 4) |
|
- quality (default: 4) |
|
- toxicity (default: 0) |
|
- humor (default: 0) |
|
- creativity (default: 0) |
|
|
|
You can change the attribute values by replacing the default values specified in the chat template: |
|
|
|
```python |
|
chatbot.tokenizer.chat_template = chatbot.tokenizer.chat_template.replace("complexity: 4", "complexity: 0") |
|
``` |
|
|
|
