Sampler

DPM++ 2M Karras / Euler a

Balances speed and detail performance

Sampling Steps

20-30 steps (28 steps recommended)

Higher steps yield richer details; 25 steps balance efficiency and quality

Resolution

1024×1536 / 1536×1024

Suitable for vertical character portraits / illustration ratios, supports 2K output

Aspect Ratio

2:3 (character portraits) / 1:1 (avatars / cards)

Matches the visual proportions of the reference images

Prompt Weight

Positive: 1.0-1.2 / Negative: -1.0~-1.5

Enhances high-quality features and avoids low-quality elements

Positive Prompt Template (adapted to reference image style)
