<span id="Introduction">模型介绍（Introduction）</span>

Nanbeige2-16B-Chat是南北阁实验室最新研发的160亿参数模型，在预训练中使用4.5T Tokens高质量语料。 在对齐阶段，我们首先使用了100万条样本进行SFT训练，然后用40万高质量且难度较高的样本进行课程学习，再通过人类反馈DPO，得到Nanbeige2-16B-Chat。Nanbeige2-16B-Chat在各个权威测评数据集上都取得了较优的效果。

The Nanbeige2-16B-Chat is the latest 16B model developed by the Nanbeige Lab, which utilized 4.5T tokens of high-quality training data during the training phase. During the alignment phase, we initially trained our model using 1 million samples through Supervised Fine-Tuning (SFT). We then engaged in curriculum learning with 400,000 high-quality samples that presented a greater level of difficulty. Subsequently, we incorporated human feedback through the Dynamic Policy Optimization (DPO), culminating in the development of Nanbeige2-16B-Chat. Nanbeige2-16B-Chat has achieved superior performance across various authoritative benchmark datasets.

<span id="Limitations">局限性（Limitations）</span>

虽然我们在训练过程中非常注重模型的安全性，力求确保其输出符合伦理和法律要求的文本，但由于模型大小和概率生成范式的限制，无法完全避免产生各种不符合预期的输出情况。这些输出可能包含偏见、歧视等有害内容，请勿传播这些内容。我们不承担因传播不良信息而导致的任何后果。

While we place great emphasis on the safety of the model during the training process, striving to ensure that its outputs align with ethical and legal requirements, it may not completely avoid generating unexpected outputs due to the model's size and probabilistic nature. These outputs may include harmful content such as bias or discrimination. Please don't propagate such content. We do not assume any responsibility for the consequences resulting from the dissemination of inappropriate information.
