BLOSSOM-v2-llama2-7b

💻Github🚀Blossom Chat Demo

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
