The model works just as well with 1024x1024 as with 512x512, portrait aspect ratios work decently enough, but might produce slight distortions.

Requires 3 steps for good outputs, but more is always worth exploring.
Keep the CFG somewhere between 1-3, 2 is a safe bet.

The following samplers seem to work well at lower step counts with the Karras scheduler:

• Euler

• Heun++2

• LMS

• DPM++2SA

• DPM++SDE

• DDIM

When paired with SGM Uniform even more samplers seem to work, I like to pair that one with DPM++SDE
