Sampling Steps
The number of steps the model goes through to create the image. More steps mean more details, but also longer generation time.

30 Steps →
50+ Steps Fast, fewer details Balanced Slow, more details
Guideline:
For most images, 20-30 steps are sufficient. Above 40-50 steps, improvements are often barely noticeable.
Sampler Algorithms
The sampler determines how the model performs the diffusion process. Each has its own strengths:
Euler a Fast with good details, somewhat creative 20-25 Steps
DPM++ 2M Karras Highly detailed, good for photorealistic images 25-30 Steps
DDIM Very stable, good for inpainting 30-40 Steps
