# SD v2.1-base with Zero Terminal SNR (LAION Aesthetic 5+)

This is the official model for [Common Diffusion Noise Schedules and Sample Steps are Flawed](https://arxiv.org/abs/2305.08891) paper.

This model is trained using the zero terminal SNR schedule on LAION aesthetic 5+ data.

This model is finetuned from [stabilityai/stable-diffusion-2-1-base](https://huggingface.co/stabilityai/stable-diffusion-2-1-base).

This model is meant for research demonstration, not for production use.

## Usage

```python
from diffusers import StableDiffusionPipeline
prompt = "A young girl smiling"
pipe = StableDiffusionPipeline.from_pretrained("ByteDance/sd2.1-base-zsnr-laionaes5").to("cuda")
pipe(prompt, guidance_scale=7.5, guidance_rescale=0.7).images[0].save("out.jpg")
```
