We propose **MaPO**, a reference-free, sample-efficient, memory-friendly alignment technique for text-to-image diffusion models. For more details on the technique, please refer to our paper [here](https://arxiv.org/abs/2406.06424). |

## Dataset |
|
|
|
This model was fine-tuned from [Stable Diffusion XL](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) on the [pixel art split of Pick-Style](https://huggingface.co/datasets/mapo-t2i/pick-style-pixel-art). |
|
|
|
## Training Code |
|
|
|
Refer to our code repository [here](https://github.com/mapo-t2i/mapo). |
|
|
|
## Inference |
|
|
|
```python |
|
from diffusers import DiffusionPipeline, AutoencoderKL, UNet2DConditionModel |
|
import torch |
|
|
|
sdxl_id = "stabilityai/stable-diffusion-xl-base-1.0" |
|
vae_id = "madebyollin/sdxl-vae-fp16-fix" |
|
unet_id = "mapo-t2i/mapo-pick-style-pixel-art" |
|
|
|
vae = AutoencoderKL.from_pretrained(vae_id, torch_dtype=torch.float16) |
|
unet = UNet2DConditionModel.from_pretrained(unet_id, subfolder='unet', torch_dtype=torch.float16) |
|
pipeline = DiffusionPipeline.from_pretrained(sdxl_id, vae=vae, unet=unet, torch_dtype=torch.float16).to("cuda") |
|
|
|
prompt = "portrait of gorgeous cyborg with golden hair, high resolution" |
|
image = pipeline(prompt=prompt, num_inference_steps=30).images[0] |
|
``` |
|
