一 模型

1.下载开源的 Stable-Diffusion 3 大模型：【点击前往】

最好时显卡6G，内存16G以上，才适合部署；

 

Stable Diffusion 3支持不同的模型规模，以适应各种硬件能力。具体来说：

Stable-Diffusion 3亮点

1. 多模态扩散变换器 (MMDiT)

Stable Diffusion 3引入了多模态扩散变换器 (MMDiT)，这是一种增强文本和图像表示的新方法。MMDiT使用独立的权重集来处理文本和图像数据，从而改善了文本理解和视觉输出。

2. 性能提升

Stable Diffusion 3在字体和提示依从性方面表现优于当前最先进的系统，例如DALL·E 3。这意味着它能够更准确地生成符合用户需求的图像。

3. 修正流 (Rectified Flows)

该模型采用修正流（Rectified Flows）技术，实现了更高效的采样过程。这种技术可以在保证生成质量的前提下，加快生成速度。

 

 

 

二 部署篇

windows部署

请求架构：

模型——ComfyUI——用户

 

具体部署

下载 ComfyUI 控制面板：【点击下载】，下面的就是绿色版本，基本的python、git还需需要安装的。

clip的模型放置到Comfyui安装目录的models\clip里面

SD3模型放置到Comfyui安装目录的models\checkpoints里面

图片放大模型放置到Comfyui安装目录的models\upscale_models里面

 

 

mac版本部署

按Shift + Cmd + U 进入实用工具目录，启动“终端”

1. 环境准备(homebrew及相关依赖包)

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install cmake protobuf rust python@3.10 git wget
pip install --upgrade pip

2. 生成安装脚本(复制代码块里的内容，进入终端粘贴，回车即可)

cat <<EOF >cfinstall.sh
{

#!/bin/bash

#创建虚拟环境
cd ~
python3 -m venv cf

#激活虚拟环境
source cf/bin/activate

#安装依赖
pip install torch torchvision torchaudio

#克隆ComfyUI代码并安装依赖
git clone https://github.com/comfyanonymous/ComfyUI
cd ComfyUI
pip install -r requirements.txt

#安装插件管理器及汉化插件
cd ~/ComfyUI/custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Manager.git
cd ComfyUI-Manager && pip install -r requirements.txt
cd ..
git clone https://github.com/AIGODLIKE/AIGODLIKE-COMFYUI-TRANSLATION.git


echo "ComfyUI部署完成!"

}
EOF

然后我们运行这个脚本进行安装：

bash cfinstall.sh

懒人启动命令如下 (已整合进入环境、进入目录及启动)：

cd ~
source cf/bin/activate && cd ComfyUI && python main.py

mac版本默认是英文，汉化包放于ComfyUI/custom_nodes目录，直接点击右上角的settings，选择语言为中文即可

三 使用篇

要想用出逼格，就需要深入理解comfyUI的逻辑

 

a female character with long, flowing hair that appears to be made of ethereal, swirling patterns resembling the Northern Lights or Aurora Borealis. The background is dominated by deep blues and purples, creating a mysterious and dramatic atmosphere. The character’s face is serene, with pale skin and striking features. She wears a dark-colored outfit with subtle patterns. The overall style of the artwork is reminiscent of fantasy or supernatural genres

On the right side of the road, there’s a blue sports car parked with the license plate spelling “SD32B”. The sky above is partly cloudy, suggesting a pleasant day. The trees have a mix of green and brown foliage. There are no people visible in the image. The overall composition is balanced, with the car serving as a focal point.
