Midjourney(MJ)和Stable Diffusion(SD)是著名的两大AIGC神器，MJ不开源且收费，SD开源免费。国内所有号称有以文生图功能的AIGC都是在SD开源版的基础上改造（或者完全不改）出来的。那么，两者的生图质量如何呢？我们做个简单的对比，使用相同的咒语（Prompt），PK最终生图。

MJ不用说，目前只能访问www.midjourney.com，或者登录Discord来使用；SD可以下载安装包安装，或者直接访问
https://stablediffusionweb.com/#demo来使用。

（以下各Prompt中，上图为MJ生成，下图为SD生成。Prompt原文为英文，中文为机翻，不准见谅。）

说心理话，我实在是不忍心把Stable Diffusion生成的图片往文章里贴。这种粗糙的图片，毫无艺术可言，俗不可耐。比地摊上铺满地的塑料“玉器”还要俗气。

Stable diffusion与Midjourney相比，缺少的不是技术，而是一个艺术家，一双具有审美细胞的眼睛！
