StableDiffusionWebUI: Sampler
Table of Contents
Preface
This chapter introduces the samplers in sdwebui.
Sampler
A sampler is the sampling method used during the SD image generation process.
Using the following prompt for txt2img, with a fixed checkpoint and fixed seed, we compare the results of different samplers.
Prompt - Chinese

Summary
-
Different samplers produce noticeably different results.
-
Checkpoint authors usually recommend a specific sampler. For example, Samaritan 3d Cartoon recommends Euler a, which works well.
-
Generally speaking, the longer the sampler name, the more internal iterations it performs — similar to iPhone generations. Give them a try, for example DPM++ 2M SDE Heun.
