This document summarizes the optimal configuration parameters for generating 1024x1360 resolution images, as well as the setting method of positive and negative sample prompt words. Designed to help users obtain high-quality image output and avoid problems such as anatomical errors, hand deformities, and blur.

Recommended settings:

• Generation steps: 30

• CFG scaling: 3.5~7 (early versions) or 5~7 (later versions)

• Sampler: Euler a (early versions) or Euler a + ADetailer face_yolov8n/s.pt (later versions)

Positive sample prompt words:

• score_9, score_8_up, score_7_up (indicates image quality with a score of 9, 8 or 7 or above)

• source_real, real skin (indicates real character skin)

Negative sample prompt words:

• worst quality, low quality (meaning the worst quality or low quality image)

• worst detail, low detail (an image with poor detail)

• source_furry, source_pony, source_cartoon, 2d (indicates furry, cartoon or two-dimensional images)

• bad anatomy, bad hands (an image indicating anatomical errors or hand deformities)

• text, error, missing fingers, fewer digits (indicates an image containing text, error, missing fingers, or fewer digits)

• cropped, bad artist, outlines, jpeg artifacts (images that are cropped, poorly painted, have outlines or jpeg compression artifacts)

• signature, watermark, username (indicates an image containing a signature, watermark, or username scrambled)

• blurry, 3d (indicating a blurry or three-dimensional image)

Update history:

• V14: Adjusted the overall color, composition and background, and fine-tuned the positive and negative sample prompt words.

• V13: Mainly adjusted the color tone and data, the character's face has basically remained unchanged, and stabilized the CFG at 7.

• V12: The recommended CFG scaling ratio is 5~7, and a 12 step version of the setting is also provided.

• V11: ADetailer face_yolov8s.pt is introduced for detail optimization.

• V10: Adjusted the prompt words for positive and negative samples to emphasize the skin texture of real people.

• V2-V9: The recommended CFG scaling ratio is 7, and is optimized using ADetailer face_yolov8n/s.pt.

• V1: Initial version, can use Euler a or DPM++ 2M Karras sampler.

Things to note:

• There may be subtle differences between different versions, please choose the appropriate configuration according to your needs.

• The role of the positive and negative sample prompt words is to guide the generator to generate images that match the description. Appropriate adjustments can improve the quality of the generation.

• Always use high-definition images as input to generate more detailed images.
