# waifu-diffusion - Diffusion for Weebs |
|
|
|
waifu-diffusion is a latent text-to-image diffusion model that has been conditioned on high-quality anime images through [Textual Inversion](https://github.com/rinongal/textual_inversion). |

## Model Description |
|
|
|
The model originally used for fine-tuning is [Stable Diffusion V1-4](https://huggingface.co./CompVis/stable-diffusion-v1-4), which is a latent image diffusion model trained on [LAION2B-en](https://huggingface.co./datasets/laion/laion2B-en). |
|
|
|
The current model is based from [Yasu Seno](https://twitter.com/naclbbr)'s [TrinArt Stable Diffusion](https://huggingface.co./naclbit/trinart_stable_diffusion) which has been fine-tuned on 30,000 high-resolution manga/anime-style images for 3.5 epochs. |
|
|
|
With [Textual Inversion](https://github.com/rinongal/textual_inversion), the embeddings for the text encoder has been trained to align more with anime-styled images, reducing excessive prompting. |
|
|
|
## Training Data & Annotative Prompting |
|
|
|
The data used for Textual Inversion has come from a random sample of 25k Danbooru images, which were then filtered based on [CLIP Aesthetic Scoring](https://github.com/christophschuhmann/improved-aesthetic-predictor) where only images with an aesthetic score greater than `6.0` were used. |
|
|
|
Captions are Danbooru-style captions. |
|
|
|
## Downstream Uses |
|
|
|
This model can be used for entertainment purposes and as a generative art assistant. |
|
|
|
## Example Code |
|
|
|
```python |
|
import torch |
|
from torch import autocast |
|
from diffusers import StableDiffusionPipeline |
|
|
|
model_id = "hakurei/waifu-diffusion" |
|
device = "cuda" |
|
|
|
|
|
pipe = StableDiffusionPipeline.from_pretrained(model_id, use_auth_token=True) |
|
pipe = pipe.to(device) |
|
|
|
prompt = "a photo of reimu hakurei. anime style" |
|
with autocast("cuda"): |
|
image = pipe(prompt, guidance_scale=7.5)["sample"][0] |
|
|
|
image.save("reimu_hakurei.png") |
|
``` |
