# llama3.1-8b-instruct 中文DPO版
|
|||
|
|
### 模型介绍
|
|||
|
|
Github：[llama3中文仓库](https://github.com/CrazyBoyM/llama3-Chinese-chat)
|
|||
|
|
像原版instruct一样，喜欢用有趣中文和表情符号回答问题。
|
|||
|
|
|
|||
|
|
|
|||
|
|
特点：偏好中文和emoji表情，且不损伤原instruct版模型能力。实测中文DPO版问答性能体验超过现在市面上任何llama3.1中文微调版 （微调会大面积破坏llama3.1原版能力，导致遗忘）
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 训练细节
|
|||
|
|
DPO(beta 0.5) + lora rank128, alpha256 + 打开"lm_head", "input_layernorm", "post_attention_layernorm", "norm"层训练.
|
|||
|
