Disty0/sote-diffusion-cascade_pre-alpha0

SoteDiffusion Cascade

Anime finetune of Stable Cascade.
Currently is in very early state in training.
No commercial use thanks to StabilityAI.

Code Example

pip install diffusers

import torch
from diffusers import StableCascadeDecoderPipeline, StableCascadePriorPipeline

prompt = "(extremely aesthetic, best quality, newest), 1girl, solo, cat ears, looking at viewer, blush, light smile, upper body,"
negative_prompt = "very displeasing, worst quality, monochrome, sketch, blurry, fat, child,"

prior = StableCascadePriorPipeline.from_pretrained("Disty0/sote-diffusion-cascade_pre-alpha0", torch_dtype=torch.float16)
decoder = StableCascadeDecoderPipeline.from_pretrained("Disty0/sote-diffusion-cascade-decoder_pre-alpha0", torch_dtype=torch.float16)

prior.enable_model_cpu_offload()
prior_output = prior(
    prompt=prompt,
    height=1024,
    width=1024,
    negative_prompt=negative_prompt,
    guidance_scale=6.0,
    num_images_per_prompt=1,
    num_inference_steps=40
)

decoder.enable_model_cpu_offload()
decoder_output = decoder(
    image_embeddings=prior_output.image_embeddings,
    prompt=prompt,
    negative_prompt=negative_prompt,
    guidance_scale=2.0,
    output_type="pil",
    num_inference_steps=10
).images[0]
decoder_output.save("cascade.png")

Limitations and Bias

Bias

• This model is intended for anime illustrations.
  Realistic capabilites are not tested at all.
• Current version has bias to older anime styles.

Limitations

• Can fall back to realistic.
  Use "anime illustration" tag to point it into the right direction.
• Far shot eyes are bad thanks to the heavy latent compression.
