Best settings:

1. Sampling Method: Euler A or Euler A SGMUniform - you can mess around with this

2. Sampling Steps: 20 ~ 60 depending on your sampling method

3. Hires. fix: Enabled

4. Hires Steps: 15 ~ 30

5. Upscaler: 4x_NMKD-YandereNeoXL_200k - You can test others.

6. Denoise Strength: 0.4

7. Upscale by: Preferably x2

8. CFG Scale: 6 ~ 9.5

9. Clip Skip: 2

Important:

Positive prompt must contain: score_9,score_8_up,score_7_up,

You can add "lineart, [artist tag], outline" for a more stylized result.

Negative prompt can be empty or contain the default pony negatives.

The promting format from Pony Diffusion V6 works well:

score_9, score_8_up, score_7_up, just describe what you want, tag1, tag2

If you haven't already, I highly reccomend reading through the Pony Diffusion V6 XL model description.

I use Forge as my main UI because it has so many optimizations for running XL/Pony models on lower end GPU's despite me having an RTX 4090, generations are alot smoother. I'm not sure how this model performs on other UI's.

I haven't done much testing. If there is anything amiss, please let me know. Feedback is always appreciated :).

Post results and, most importantly, have fun!
