 ## 介绍
 
 ChatGLM-6B 是一个开源的、支持中英双语的对话语言模型，基于 [General Language Model (GLM)](https://github.com/THUDM/GLM) 架构，具有 62 亿参数。结合模型量化技术，用户可以在消费级的显卡上进行本地部署（INT4 量化级别下最低只需 6GB 显存）。
-ChatGLM-6B 使用了和 ChatGPT 相似的技术，针对中文问答和对话进行了优化。经过约 1T 标识符的中英双语训练，辅以监督微调、反馈自助、人类反馈强化学习等技术的加持，62 亿参数的 ChatGLM-6B 已经能生成相当符合人类偏好的回答，更多信息请参考我们的[博客](https://chatglm.cn/blog)。

 为了方便下游开发者针对自己的应用场景定制模型，我们同时实现了基于 [P-Tuning v2](https://github.com/THUDM/P-tuning-v2) 的高效参数微调方法 [(使用指南)](ptuning/README.md) ，INT4 量化级别下最低只需 7GB 显存即可启动微调。

 ## Introduction
 
-ChatGLM-6B is an open bilingual language model based on [General Language Model (GLM)](https://github.com/THUDM/GLM) framework, with 6.2 billion parameters. With the quantization technique, users can deploy locally on consumer-grade graphics cards (only 6GB of GPU memory is required at the INT4 quantization level).

With the quantization technique, users can deploy locally on consumer-grade graphics cards (only 6GB of GPU memory is required at the INT4 quantization level). Welcome to use the larger ChatGLM model on [chatglm.cn](https://chatglm.cn) 
 
 ChatGLM-6B uses technology similar to ChatGPT, optimized for Chinese QA and dialogue. The model is trained for about 1T tokens of Chinese and English corpus, supplemented by supervised fine-tuning, feedback bootstrap, and reinforcement learning wit human feedback. With only about 6.2 billion parameters, the model is able to generate answers that are in line with human preference.
 
 In order to facilitate downstream developers to customize the model for their own application scenarios, we also implements an parameter-efficient tuning method based on [P-Tuning v2](https://github.com/THUDM/P-tuning-v2)[(Guidelines)](ptuning/README_en.md). Tuning requires at least 7GB of GPU memory at INT4 quantization level.
 
+ChatGLM-6B weights are **completely open** for academic research, and **free commercial use** is also allowed after completing the [questionnaire](https://lslfd0slxc.feishu.cn/share/base/form/shrcnfAj1ZnGOW7kqAfiHFcAFXc).
