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 |

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.
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
from transformers.generation.utils import GenerationConfig
tokenizer = AutoTokenizer.from_pretrained("baichuan-inc/Baichuan2-7B-Chat", use_fast=False, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("baichuan-inc/Baichuan2-7B-Chat", device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True)
model.generation_config = GenerationConfig.from_pretrained("baichuan-inc/Baichuan2-7B-Chat")
messages = []
messages.append({"role": "user", "content": "解释一下“温故而知新”"})
response = model.chat(tokenizer, messages)
print(response)
"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。

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.
