高质量的模型，能够成倍提升出图质量。

常见模型分类
常见的模型主要分为四类：Checkpoint、LoRA、Textual Inversion、Hypernetwork，分别对应 4 种不同的训练方式。
Checkpoint：通过 Dreambooth 训练方式得到的大模型， 特点是出图效果好，但由于训练的是一个完整的新模型，所以训练速度普遍较慢，生成模型文件较大，一般几个 G，文件格式为 safetensors 或 ckpt。
LoRA：一种轻量化的模型微调训练方法，是在原有大模型的基础上，对该模型进行微调，用于输出固定特征的人或事物。特点是对于特定风格特征的出图效果好，训练速度快，模型文件小，一般几十到一百多 MB，需要搭配大模型使用。
Textual Inversion：一种使用文本提示来训练模型的方法，可以简单理解为一组打包的提示词，用于生成固定特征的人或事物。特点是对于特定风格特征的出图效果好，模型文件非常小，一般几十 K，但是训练速度较慢，需要搭配大模型使用。
Hypernetwork：类似 LoRA，但模型效果不如 LoRA，需要搭配大模型使用。
模型推荐：Checkpoint > LoRA > Textual Inversion > Hypernetwork

通常情况 Checkpoint 模型搭配 LoRA 或 Textual Inversion 模型使用，可以获得更好的出图效果。
补充：还有一类 VAE 模型，简单理解它的作用就是提升图像色彩效果，让画面看上去不会那么灰蒙蒙，此外对图像细节进行细微调整。




Fine-tuned Model Checkpoints (Dreambooth Models)

• Download the custom model
• Place the model inside the models/Stable-diffusion directory of your AUTOMATIC1111 Web UI instance
• Refresh your model list or restart the Stable Diffusion Web UI
• Select the custom model from the Stable Diffusion checkpoint input field
• Use the trained keyword in a prompt (listed on the custom model's page)
• Make awesome images!
  

Checkpoints 模型：放在models/Stable-diffusion 目录下

Textual Inversions

• Download the textual inversion
• Place the textual inversion inside the embeddings directory of your AUTOMATIC1111 Web UI instance
• Use the trained keyword in a prompt (listed on the textual inversion's page)
• Make awesome images!
  

Textual Inversions（文本）：放在embeddings 目录下

Aesthetic Gradients

• Install the Aesthetic Gradients extension
• Download the aesthetic gradient
• Place the aesthetic graident inside the aesthetic_embeddings directory of your AUTOMATIC1111 Web UI instance
• Restart the Stable Diffusion Web UI
• Adjust the aesthetic gradient setting
• Make awesome images!
  

Aesthetic Gradients(梯度)：放在 aesthetic_embeddings目录下

Hypernetwork

• Download the hypernetwork
• Place the hypernetwork inside the models/hypernetworks directory of your AUTOMATIC1111 Web UI instance
• Restart the Stable Diffusion Web UI
• Select the hypernetwork from the Hypernetwork input field in settings
• Adjust the hypernetwork strength using the Hypernetwork strength range slider in settings
• Make awesome images!
  

Hypernetwork（超级网络）：放在 models/hypernetworks目录下

LoRA

Video Guide by Lykon

• Download the LoRA
• Place the file inside the models/lora folder
• Click on the show extra networks button under the Generate button (purple icon)
• Go to the Lora tab and refresh if needed
• Click on the one you want to apply, it will be added in the prompt
• Make sure to adjust the weight, by default it's :1 which is usually to high
  

LORA：放在 models/lora目录下
（Low-Rank Adaptation of Large Language Models 基于大型语言模型的低阶自适应，是经过特殊训练后的一个微调补充）

LoRA
Old UI (Versions Prior to Jan 20th) 旧版

• Ensure that you've installed the Additional Networks extension, you can do this from the extensions tab. After installing you will need to restart AUTOMATIC1111.
• Download the LoRA
• Place the file inside the extensions/sd-webui-additional-networks/models/lora folder
• On the txt2img or img2img tab, dropdown the Additional Networks area at the bottom of the page
• Check enable
• Set Model 1 to the LoRA model you downloaded
• Set Weight 1 to a 0.85 a good starting value and adjust as needed
• Make awesome images!
  

确保安装了Additional Networks，然后放在extensions/sd-webui-additional-networks/models/lora目录下。

Note: You can use a LoRA with any model, but usually they are trained on a specific model and will perform best on that model or a derivative of that model.

LoRA可以用于任何模型下，但是实际上最好是放在训练时的大模型下能达到最佳效果。

LoCon

• Ensure that you're utilizing the latest version of Automatic1111 or that you've installed the   LoCon Extension
• Download the LoCon
• Place the file inside the models/LyCORIS folder
• Click on the show extra networks button under the Generate button (purple icon)
• Go to the LyCORIS tab and refresh if needed
• Click on the one you want to apply, it will be added in the prompt
• Make sure to adjust the weight, by default it's :1 which is usually too high
  

LoCon：放在 models/LyCORIS目录下

Wildcards

• Ensure that you've installed the Wildcard Extension
• Download the Wildcards archive
• Extract the archive into extensions/stable-diffusion-webui-wildcards/wildcards
• Use one or many of the wildcard words in your prompt to trigger the word replacement on generation (ex. __hair-style__)
  

Wildcards：确保安装了 Wildcard 扩展，然后放在extensions/stable-diffusion-webui-wildcards/wildcards目录下

Motion Module

• Ensure that you've installed the AnimateDiff Extension
• Download the Motion Module
• Place the file inside the extensions/sd-webui-animatediff/model/ folder
  

Motion Module：确保安装了AnimateDiff 扩展，然后放在extensions/sd-webui-animatediff/model/ 目录下

目前 CivitAI（俗称 C 站， https://civitai.com/ ）是业内比较成熟的一个 Stable Diffusion 模型社区，上面汇集了上千个模型，以及上万张附带提示词的图像，这大大降低了 Stable Diffusion 的入门学习成本。

这里有简要介绍 C 站的一些优秀模型，并结合示例进行应用说明。
