### 介绍
|
|||
|
|
|
|||
|
|
Blossom是一个对话式语言模型，基于Llama-2-7b预训练模型，在Blossom、Wizard、Dolphin混合数据集上进行指令精调得来。
|
|||
|
|
|
|||
|
|
训练分为两阶段，第一阶段使用120K Wizard、180K Dolphin单轮指令数据集，训练1个epoch；第二阶段使用60K Blossom chat、2K Blossom math多轮对话数据集，训练3个epoch。
|
|||
|
|
|
|||
|
|
注意：Llama-2-7b预训练模型的中文知识较为欠缺，因此对于中文场景，更推荐使用[blossom-v2-baichuan-7b](https://huggingface.co/Azure99/blossom-v2-baichuan-7b)

### 推理

|||
|
|
|
|||
|
|
推理采用对话续写的形式。
