# Unichat-llama3-Chinese-8B


## 介绍
* 中国联通发布业界第一个llama3中文指令微调模型，2024年4月19日22点
* 本模型以[**Meta Llama 3**](https://huggingface.co/collections/meta-llama/meta-llama-3-66214712577ca38149ebb2b6)为基础,增加中文数据进行训练,实现llama3模型高质量中文问答,模型支持原生长度为8K
* 基础模型 [**Meta-Llama-3-8B**](https://huggingface.co/meta-llama/Meta-Llama-3-8B)

### 📊 数据
- 高质量指令数据，覆盖多个领域和行业，为模型训练提供充足的数据支持。
- 微调指令数据经过严格的人工筛查，保证优质的指令数据用于模型微调
  
## 快速开始

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

model_id = "UnicomLLM/Unichat-llama3-Chinese-8B"

pipeline = transformers.pipeline(
    "text-generation",
    model=model_id,
    model_kwargs={"torch_dtype": torch.bfloat16},
    device="cuda",
)


messages = [
    {"role": "system", "content": "You are a helpful assistant"},
    {"role": "user", "content": "Who are you?"},
]


prompt = pipeline.tokenizer.apply_chat_template(
      messages,
      tokenize=False,
      add_generation_prompt=True
)

terminators = [
      pipeline.tokenizer.eos_token_id,
      pipeline.tokenizer.convert_tokens_to_ids("<|eot_id|>")
]


outputs = model.generate(
      prompt,
      max_new_tokens=2048,
      eos_token_id=terminators,
      do_sample=False,
      temperature=0.6,
      top_p=1,
      repetition_penalty=1.05
)
response = outputs[0][input_ids.shape[-1]:]
print(tokenizer.decode(response, skip_special_tokens=True))
```
