💻 Usage Examples

Basic Usage

import torch
from diffusers import StableDiffusionXLPipeline

pipe = StableDiffusionXLPipeline.from_pretrained(
    "yodayo-ai/holodayo-xl-2.1", 
    torch_dtype=torch.float16, 
    use_safetensors=True,
    custom_pipeline="lpw_stable_diffusion_xl",
    add_watermarker=False,
    variant="fp16"
)
pipe.to('cuda')

prompt = "1girl, nakiri ayame, nakiri ayame \(1st costume\), hololive, solo, upper body, v, smile, looking at viewer, outdoors, night, masterpiece, best quality, very aesthetic, absurdres"
negative_prompt = "nsfw, (low quality, worst quality:1.2), very displeasing, 3d, watermark, signature, ugly, poorly drawn"

image = pipe(
    prompt, 
    negative_prompt=negative_prompt,
    width=832,
    height=1216, 
    guidance_scale=7,
    num_inference_steps=28
).images[0]

Usage Guidelines

Tag Ordering

For optimal results, it's recommended to follow the structured prompt template because we train the model like this:

1girl/1boy, character name, from which series, by which artists, everything else in any order.

Special Tags

Holodayo XL 2.1 inherits special tags from Animagine XL 3.1 to enhance image generation by steering results toward quality, rating, creation date, and aesthetic. This inheritance ensures that Holodayo XL 2.1 can produce high - quality, relevant, and aesthetically pleasing images. While the model can generate images without these tags, using them helps achieve better results.

• Quality tags: masterpiece, best quality, great quality, good quality, normal quality, low quality, worst quality
• Rating tags: safe, sensitive, nsfw, explicit
• Year tags: newest, recent, mid, early, oldest
• Aesthetic tags: very aesthetic, aesthetic, displeasing, very displeasing

Recommended Settings

To guide the model towards generating high - aesthetic images, use the following recommended settings:

• Negative prompts:

nsfw, (low quality, worst quality:1.2), very displeasing, 3d, watermark, signature, ugly, poorly drawn

• Positive prompts:

masterpiece, best quality, very aesthetic, absurdres

• Classifier - Free Guidance (CFG) Scale: should be around 5 to 7; 10 is fried, >12 is deep - fried.
• Sampling steps: should be around 25 to 30; 28 is the sweet spot.
• Sampler: Euler Ancestral (Euler a) is highly recommended.
• Supported resolutions:

1024 x 1024, 1152 x 896, 896 x 1152, 1216 x 832, 832 x 1216, 1344 x 768, 768 x 1344, 1536 x 640, 640 x 1536
