## 简介 Brief Introduction
Ziya2-13B-Base 是基于LLaMa2的130亿参数大规模预训练模型，针对中文分词优化，并完成了中英文 650B tokens 的增量预训练，进一步提升了中文生成和理解能力。
The Ziya2-13B-Base is a large-scale pre-trained model based on LLaMA2 with 13 billion parameters. We optimizes LLaMAtokenizer on chinese, and incrementally train 650 billion tokens of data based on LLaMa2-13B model, which significantly improved the understanding and generation ability on Chinese.

## 模型信息 Model Information
### 继续预训练 Continual Pretraining
Meta在2023年7月份发布了Llama2系列大模型，相比于LLaMA1的1.4万亿Token数据，Llama2预训练的Token达到了2万亿，并在各个榜单中明显超过LLaMA1。
Meta released the Llama2 series of large models in July 2023, with pre-trained tokens reaching 200 billion compared to Llama1's 140 billion tokens, significantly outperforming Llama1 in various rankings.
Ziya2-13B-Base沿用了Ziya-LLaMA-13B高效的中文编解码方式，但采取了更优化的初始化算法使得初始训练loss更低。同时，我们对Fengshen-PT继续训练框架进行了优化，效率方面，整合了FlashAttention2、Apex RMS norm等技术来帮助提升效率，对比Ziya-LLaMA-13B训练速度提升38%(163 TFLOPS/per gpu/per sec)。稳定性方面，我们采取BF16进行训练，修复了底层分布式框架的bug，确保模型能够持续稳定训练，解决了Ziya-LLaMA-13B遇到的训练后期不稳定的问题，并在7.25号进行了直播，最终完成了全部数据的继续训练。我们也发现，模型效果还有进一步提升的趋势，后续也会对Ziya2-13B-Base进行继续优化。
Ziya2-13B-Base retained the efficient Chinese encoding and decoding techniques of Ziya-LLaMA-13B, but employed a more optimized initialization algorithm to achieve lower initial training loss. Additionally, we optimized the Fengshen-PT fine-tuning framework. In terms of efficiency, we integrated technologies such as FlashAttention2 and Apex RMS norm to boost efficiency, resulting in a 38% increase in training speed compared to Ziya-LLaMA-13B (163 TFLOPS per GPU per second). For stability, we used BF16 for training, fixed underlying distributed framework bugs to ensure consistent model training, and resolved the late-stage instability issues encountered in the training of Ziya-LLaMA-13B. We also conducted a live broadcast on July 25th to complete the continued training of all data. We have observed a trend towards further improvements in model performance and plan to continue optimizing Ziya2-13B-Base in the future.
### 效果评估 Performance
Ziya2-13B-Base在Llama2-13B的基础上进行了约650B自建高质量中英文数据集的继续训练，在中文、英文、数学、代码等下游理解任务上相对于Llama2-13B取得了明显的提升，相对Ziya-LLaMA-13B也有明显的提升。
The model Ziya2-13B-Base underwent further training on approximately 650 billion self-collected high-quality Chinese and English datasets, building upon the foundation of Llama2-13B. It achieved significant improvements in downstream comprehension tasks such as Chinese, English, mathematics, and code understanding, surpassing Llama2-13B and showing clear advancements compared to Ziya-LLaMA-13B.
