5.5 SDXL 使用指南

本小节主要介绍SDXL 模型的使用，从SDXL 模型出发详细了解如何对模型参数进行的优化使用

SDXL 是 Stable Diffusion 的最新版本，是潜在扩散模型，能够从文本描述中生成高分辨率、高质量、高逼真的图像。SDXL 版本相比于之前的版本，在文本理解、图像细节、色彩表现等方面都有显著的提升。SDXL 不仅能够生成写实风格的图像，也能够生成各种艺术风格的图像，例如卡通、油画、水彩、素描等，只需要在文本描述中加入相应的风格提示词，就可以让 SDXL 按照预定的设计来创作。

• 1、SDXL Base model使用

• 2、SDXL Refiner model使用

• 3、SDXL 风格提示词

首先是可以看到的在系统之中是有模型文件存在的。如果没有可以在下面的过程之中进行下载。

1、SDXL Base model使用

参数设置：

模型选择：SDXL_10 或 SDXL_90

尺寸：1024*1024

计算步数：20

精准度：7

采样器：Eular a

我们可以看到采样的方式会影响到生成的图像。

2、SDXL Refiner model使用

为什么使用Refiner：refiner model能够基于base model结果优化生成的图片质量，在Aidraw目前支持通过图生图方式使用refiner模型，后续将支持自动refiner生图。

在生图结果点击图生图

参数设置：

参考图：使用base model 生成图

Prompt：使用与base model相同Prompt

模型选择：SDXL_Refiner_10 或 SDXL_Refiner_09

重绘强度：0.25（重绘强度需要控制在这个范围左右，否则效果会变差）

尺寸：1024*1024

计算步数：20

精准度：7

采样器：Eular a
