Hitokomoru Diffusion V2
A latent diffusion model that has been trained on Japanese Artist artwork, γγγγγ/Hitokomoru. The current model is fine-tuned from waifu-diffusion-1-4 (wd-1-4-anime_e2.ckpt
) with a learning rate of 2.0e-6
, 15000 training steps and 4 batch sizes on the 257 artworks
collected from Danbooru. This model supposed to be a continuation of hitokomoru-diffusion fine-tuned from Anything V3.0. Dataset has been preprocessed using Aspect Ratio Bucketing Tool so that it can be converted to latents and trained at non-square resolutions. Like other anime-style Stable Diffusion models, it also supports Danbooru tags to generate images.
e.g. 1girl, white hair, golden eyes, beautiful eyes, detail, flower meadow, cumulonimbus clouds, lighting, detailed sky, garden

Model Details
- Developed by: Linaqruf
- Model type: Diffusion-based text-to-image generation model
- Model type: This is a model that can be used to generate and modify images based on text prompts.
- License: CreativeML Open RAIL++-M License
- Finetuned from model: waifu-diffusion-v1-4-epoch-2
How to Use
- Download the
hitokomoru-v2.ckpt
here, or download the safetensors version here. - This model is fine-tuned from waifu-diffusion-v1-4-epoch-2, which is also fine-tuned from stable-diffusion-2-1-base. So in order to run this model in
Automatic1111's Stable Diffusion Webui
, you need to put inference config .YAML file next to the model, you can find it here - You need to adjust your prompt using aesthetic tags, Based Official Waifu Diffusion 1.4 release notes, an ideal negative prompt to guide the model towards high aesthetic generations would look like:
worst quality, low quality, medium quality, deleted, lowres, comic, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, jpeg artifacts, signature, watermark, username, blurry
- And, the following should also be prepended to prompts to get high aesthetic results:
masterpiece, best quality, high quality, absurdres
𧨠Diffusers
This model can be used just like any other Stable Diffusion model. For more information, please have a look at the Stable Diffusion. You can also export the model to ONNX, MPS and/or FLAX/JAX.
You should install dependencies below in order to running the pipeline
pip install diffusers transformers accelerate scipy safetensors
Running the pipeline (if you don't swap the scheduler it will run with the default DDIM, in this example we are swapping it to DPMSolverMultistepScheduler):
import torch
from torch import autocast
from diffusers import StableDiffusionPipeline, DPMSolverMultistepScheduler
model_id = "Linaqruf/hitokomoru-diffusion-v2"
# Use the DPMSolverMultistepScheduler (DPM-Solver++) scheduler here instead
pipe = StableDiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.float16)
pipe.scheduler = DPMSolverMultistepScheduler.from_config(pipe.scheduler.config)
pipe = pipe.to("cuda")
prompt = "masterpiece, best quality, high quality, 1girl, solo, sitting, confident expression, long blonde hair, blue eyes, formal dress"
negative_prompt = "worst quality, low quality, medium quality, deleted, lowres, comic, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, jpeg artifacts, signature, watermark, username, blurry"
with autocast("cuda"):
image = pipe(prompt,
negative_prompt=negative_prompt,
width=512,
height=728,
guidance_scale=12,
num_inference_steps=50).images[0]
image.save("anime_girl.png")
Example
Here is some cherrypicked samples:
Prompt and settings for Example Images
masterpiece, best quality, high quality, 1girl, solo, sitting, confident expression, long blonde hair, blue eyes, formal dress, jewelry, make-up, luxury, close-up, face, upper body.
Negative prompt: worst quality, low quality, medium quality, deleted, lowres, comic, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, jpeg artifacts, signature, watermark, username, blurry
