StableDiffusionWebUI: Sampling Steps

Preface

This section introduces the sampling steps in sdwebui.

Sampling Steps

The previous section covered samplers: https://blog.vincentqiao.com/sd-sampler

Sampling steps refer to the number of noise addition and denoising iterations during image generation.

Summary

  1. Too few steps means the denoising process is incomplete, making the result basically unusable.

  2. Too many steps yields diminishing returns in optimization.

  3. Checkpoint authors usually recommend a specific step count. In practice, 20-30 steps generally produce good results.
