# Model Card for Model ID

Original model [elyza/ELYZA-japanese-Llama-2-7b-fast-instruct](https://huggingface.co/elyza/ELYZA-japanese-Llama-2-7b-fast-instruct) which is based on Meta's "Llama 2" and has undergone additional pre-training in Japanese, and thier original post-training and speed up tuning.

This model is a quantized(miniaturized to 4.11GB) version of the original model(13.69GB).  

## Model Details

Quantization reduces the amount of memory required and improves execution speed, but unfortunately performance deteriorates.  

In particular, the original model is tuned for the purpose of strengthening the ability to follow Japanese instructions, not as a benchmark.  

Although the ability to follow instructions cannot be measured using existing automated benchmarks, we have confirmed that quantized model significantly deteriorates the ability to follow instructions.

At least one GPU is currently required due to a limitation of the Accelerate library.  
So this model cannot be run with the huggingface space free version.
You need [autoGPTQ](https://github.com/PanQiWei/AutoGPTQ) library to use this model.

## Other Quantized Model

### New!
[dahara1/ELYZA-japanese-Llama-2-7b-instruct-AWQ](https://huggingface.co/dahara1/ELYZA-japanese-Llama-2-7b-instruct-AWQ) is newly published.  
The awq model has improved ability to follow instructions, so please try it.  

There are another two [llama.cpp](https://github.com/ggerganov/llama.cpp) version quantized model.  
If you want to run it in a CPU-only environment, you may want to check this.  

(1)[mmnga's gguf version](https://huggingface.co/mmnga/ELYZA-japanese-Llama-2-7b-fast-instruct-gguf)  
(2)[opparco's gguf version](https://huggingface.co/opparco/ELYZA-japanese-Llama-2-7b-fast-instruct-gguf)

### Sample Code

```
pip install auto-gptq
```

```
from transformers import AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM

quantized_model_dir = "dahara1/ELYZA-japanese-Llama-2-7b-fast-instruct-GPTQ"

model_basename = "gptq_model-4bit-128g"
tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir)

model = AutoGPTQForCausalLM.from_quantized(
        quantized_model_dir,
        model_basename=model_basename,
        use_safetensors=True,
        disable_exllama=False,
        inject_fused_attention=False,
        device="cuda:0")

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。"
text = "クマが海辺に行ってアザラシと友達になり、最終的には家に帰るというプロットの短編小説を書いてください。"

prompt = "{bos_token}{b_inst} {system}{prompt} {e_inst} ".format(
    bos_token=tokenizer.bos_token,
    b_inst=B_INST,
    system=f"{B_SYS}{DEFAULT_SYSTEM_PROMPT}{E_SYS}",
    prompt=text,
    e_inst=E_INST,
)

tokens = tokenizer(prompt, return_tensors="pt").to("cuda:0").input_ids
output = model.generate(
        input_ids=tokens,
        max_new_tokens=256,
        pad_token_id=tokenizer.pad_token_id,
        eos_token_id=tokenizer.eos_token_id)
print(tokenizer.decode(output[0]))
```

result.

### Colab Sample with extra benchmark

[Colab Sample with extra benchmark](https://github.com/webbigdata-jp/python_sample/blob/main/ELYZA_japanese_Llama_2_7b_fast_instruct_GPTQ_sample.ipynb)

elyza_tasks_100_over_4score_prompt borrows data from [ELYZA-tasks-100 評価結果シート](https://docs.google.com/spreadsheets/d/1mtoy4QAqDPk2f_B0vDogFoOrbA5G42DBEEHdqM4VmDI/edit#gid=1023787356).  

The original model was able to perform well at these prompts but this model does not always give good results.  
So if you need high performance, please use the original model.
