22
+ ## 介绍
23
+ ChatGLM3-6B 是 ChatGLM 系列最新一代的开源模型,在保留了前两代模型对话流畅、部署门槛低等众多优秀特性的基础上,ChatGLM3-6B 引入了如下特性:
24
+
25
+ 1. **更强大的基础模型:** ChatGLM3-6B 的基础模型 ChatGLM3-6B-Base 采用了更多样的训练数据、更充分的训练步数和更合理的训练策略。在语义、数学、推理、代码、知识等不同角度的数据集上测评显示,ChatGLM3-6B-Base 具有在 10B 以下的预训练模型中最强的性能。
26
+ 2. **更完整的功能支持:** ChatGLM3-6B 采用了全新设计的 [Prompt 格式](PROMPT.md),除正常的多轮对话外。同时原生支持[工具调用](tool_using/README.md)(Function Call)、代码执行(Code Interpreter)和 Agent 任务等复杂场景。
27
+ 3. **更全面的开源序列:** 除了对话模型 ChatGLM3-6B 外,还开源了基础模型 ChatGLM-6B-Base、长文本对话模型 ChatGLM3-6B-32K。以上所有权重对学术研究**完全开放**,在填写[问卷](https://open.bigmodel.cn/mla/form)进行登记后**亦允许免费商业使用**。
28
+
29
+ 本仓库为 ChatGLM3-6B 的基础模型 ChatGLM3-6B-Base。
30
+
31
+ ## 软件依赖
32
+
33
+ ```shell
34
+ pip install protobuf transformers==4.30.2 cpm_kernels torch>=2.0 gradio mdtex2html sentencepiece accelerate
35
+ ```
36
+
37
+ ## 代码调用
38
+
39
+ 作为没有经过人类意图对齐的模型,ChatGLM3-6B-Base 不能用于多轮对话。但是可以进行文本续写。
40
+
41
+ ```python
42
+ from transformers import AutoTokenizer, AutoModel
43
+ tokenizer = AutoTokenizer.from_pretrained("THUDM/chatglm3-6b-base", trust_remote_code=True)
44
+ model = AutoModel.from_pretrained("THUDM/chatglm3-6b-base", trust_remote_code=True).half().cuda()
45
+
46
+ inputs = tokenizer(["今天天气真不错"], return_tensors="pt").to('cuda')
47
+ outputs = tokenizer.generate(**inputs)
48
+ print(tokenizer.decode(outputs[0].tolist()))
49
+ ```
50
+
51
+ 关于更多的使用说明,包括如何运行命令行和网页版本的 DEMO,以及使用模型量化以节省显存,请参考我们的 [Github Repo](https://github.com/THUDM/ChatGLM)。
