“温故而知新”有四解：
一为“温故才知新”,温习已学的知识，并且由其中获得新的领悟；
二为“温故及知新”：一方面要温习典章故事，另一方面又努力撷取新的知识。
三为，温故，知新。随着自己阅历的丰富和理解能力的提高，回头再看以前看过的知识，总能从中体会到更多的东西。
第四，是指通过回味历史，而可以预见，以及解决未来的问题。这才是一个真正的大师应该具有的能力。
合并这四种解法，也许更为完整：在能力范围以内，尽量广泛阅览典籍，反复思考其中的涵义，对已经听闻的知识，也要定期复习，能有心得、有领悟；并且也要尽力吸收新知；如此则进可以开拓人类知识的领域，退也可以为先贤的智能赋予时代的意义。像这样融汇新旧、贯通古今方可称是“温故而知新,可以为师矣”。
也有学者以为作“温故及知新”解不太合适，因为按字面上解释，仅做到吸收古今知识而未有领悟心得，只像是知识的买卖者，不足以为师。所以我们就来看看“师”的意义：在论语中师字一共见于14章，其中意义与今日的老师相近者，除本章外还有三章。

“温故而知新”有多种解释方式。一种解释是，通过回顾和重温学过的知识，可以获得新的理解和领悟。另一种解释是，既要温习过去的经典和文化传统，又要努力汲取新的知识和经验。还有一种解释是通过回顾历史，可以预见未来并解决问题。综合这些解释，“温故而知新”意味着在学习过程中要不断回顾和反思，以获得新的见解和认识。

模型介绍/Introduction

Baichuan 2 是百川智能推出的新一代开源大语言模型，采用 2.6 万亿 Tokens 的高质量语料训练，在权威的中文和英文 benchmark 上均取得同尺寸最好的效果。本次发布包含有 7B、13B 的 Base 和 Chat 版本，并提供了 Chat 版本的 4bits 量化，所有版本不仅对学术研究完全开放，开发者也仅需邮件申请并获得官方商用许可后，即可以免费商用。具体发布版本和下载见下表：

Baichuan 2 is the new generation of large-scale open-source language models launched by Baichuan Intelligence inc.. It is trained on a high-quality corpus with 2.6 trillion tokens and has achieved the best performance in authoritative Chinese and English benchmarks of the same size. This release includes 7B and 13B versions for both Base and Chat models, along with a 4bits quantized version for the Chat model. All versions are fully open to academic research, and developers can also use them for free in commercial applications after obtaining an official commercial license through email request. The specific release versions and download links are listed in the table below:

	Base Model	Chat Model	4bits Quantized Chat Model
7B	Baichuan2-7B-Base	Baichuan2-7B-Chat	Baichuan2-7B-Chat-4bits
13B	Baichuan2-13B-Base	Baichuan2-13B-Chat	Baichuan2-13B-Chat-4bits

快速开始/Quick Start

在Baichuan2系列模型中，我们为了加快推理速度使用了Pytorch2.0加入的新功能F.scaled_dot_product_attention，因此模型需要在Pytorch2.0环境下运行。

In the Baichuan 2 series models, we have utilized the new feature F.scaled_dot_product_attention introduced in PyTorch 2.0 to accelerate inference speed. Therefore, the model needs to be run in a PyTorch 2.0 environment.

"温故而知新"是一句中国古代的成语，出自《论语·为政》篇。这句话的意思是：通过回顾过去，我们可以发现新的知识和理解。换句话说，学习历史和经验可以让我们更好地理解现在和未来。

这句话鼓励我们在学习和生活中不断地回顾和反思过去的经验，从而获得新的启示和成长。通过重温旧的知识和经历，我们可以发现新的观点和理解，从而更好地应对不断变化的世界和挑战。

Benchmark 结果/Benchmark Evaluation

我们在通用、法律、医疗、数学、代码和多语言翻译六个领域的中英文权威数据集上对模型进行了广泛测试，更多详细测评结果可查看GitHub。

We have extensively tested the model on authoritative Chinese-English datasets across six domains: General, Legal, Medical, Mathematics, Code, and Multilingual Translation. For more detailed evaluation results, please refer to GitHub.

训练过程模型/Training Dynamics

除了训练了 2.6 万亿 Tokens 的 Baichuan2-7B-Base 模型，我们还提供了在此之前的另外 11 个中间过程的模型（分别对应训练了约 0.2 ~ 2.4 万亿 Tokens）供社区研究使用（训练过程checkpoint下载）。下图给出了这些 checkpoints 在 C-Eval、MMLU、CMMLU 三个 benchmark 上的效果变化：

In addition to the Baichuan2-7B-Base model trained on 2.6 trillion tokens, we also offer 11 additional intermediate-stage models for community research, corresponding to training on approximately 0.2 to 2.4 trillion tokens each (Intermediate Checkpoints Download). The graph below shows the performance changes of these checkpoints on three benchmarks: C-Eval, MMLU, and CMMLU.
