Steps to generate a image

1. Select model (default is v1-5….)
2. Type text prompt & negative text prompt
3. Setting Parameters
4. Download image
   • Click the button
   • Wait for the “number changed” before download
   • Download the image

Parameter Guidance:

Tex-to-image :

• Steps: 20 - 50
• Width & Height:
  • for SD 1.5: Optimal at 512, 720 is fine,, repetition appears after
  • for SDXL 1.0: Optimal at 1024,
• Sampling Method: not sure what’s the difference but they add different flavor to the images
• CFG Scale: around 7.0, up to 14 ; lower → more abstract, broken images | higher → more “finished” images

Img-to-img:

• Denoising Strength: define how far the result can be changed from the original image. Also affecting the total producing time because the actual steps it takes to generate the image is the setting steps times the denoising ratio. For example, if you set 50 steps and pair with a denoising ration of 0.7, then the actual steps of producing the image is 50x0.7 = 35 steps.
