Evt_V4-preview

EVT series is an experimental project for finetune with large datasets on animation style model. Evt_V4 uses a larger dataset than before, and its cosine similarity with ACertainty reaches 85%. It may behave differently from other models, hope you enjoy it.

🧨 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.

from diffusers import StableDiffusionPipeline
import torch

model_id = "haor/Evt_V4-preview"
branch_name= "main"

pipe = StableDiffusionPipeline.from_pretrained(model_id, revision=branch_name, torch_dtype=torch.float16)
pipe = pipe.to("cuda")

prompt = "1girl"
image = pipe(prompt).images[0]

image.save("./1girl.png")
