We propose ResAdapter, a plug-and-play resolution adapter for enabling any diffusion model generate resolution-free images: no additional training, no additional inference and no style transfer.

Download

Models

We have released all resadapter weights, you can download resadapter models from Huggingface. The following is our resadapter model card:

Models	Parameters	Resolution Range	Ratio Range	Links
resadapter_v2_sd1.5	0.9M	128 <= x <= 1024	0.28 <= r <= 3.5	Download
resadapter_v2_sdxl	0.5M	256 <= x <= 1536	0.28 <= r <= 3.5	Download
resadapter_v1_sd1.5	0.9M	128 <= x <= 1024	0.5 <= r <= 2	Download
resadapter_v1_sd1.5_extrapolation	0.9M	512 <= x <= 1024	0.5 <= r <= 2	Download
resadapter_v1_sd1.5_interpolation	0.9M	128 <= x <= 512	0.5 <= r <= 2	Download
resadapter_v1_sdxl	0.5M	256 <= x <= 1536	0.5 <= r <= 2	Download
resadapter_v1_sdxl_extrapolation	0.5M	1024 <= x <= 1536	0.5 <= r <= 2	Download
resadapter_v1_sdxl_interpolation	0.5M	256 <= x <= 1024	0.5 <= r <= 2	Download

Hint1: We update the resadapter name format according to controlnet.

Hint2: If you want use resadapter with personalized diffusion models, you should download them from CivitAI.

Hint3: If you want use resadapter with ip-adapter, controlnet and lcm-lora, you should download them from Huggingface.

Hint4: Here is an installation guidance for preparing environment and downloading models.

Inference

If you want generate images in our inference script, you should install dependency libraries and download related models according to installation guidance. After filling in example configs, you can directly run this script.

python main.py --config /path/to/file

I am learning how to make webui extension.

Local Gradio Demo

Run the following script:

# pip install peft, gradio, httpx==0.23.3
python app.py

Usage Tips

If you are not satisfied with interpolation images, try to increase the alpha of resadapter to 1.0.
If you are not satisfied with extrapolate images, try to choose the alpha of resadapter in 0.3 ~ 0.7.
If you find the images with style conflicts, try to decrease the alpha of resadapter.
If you find resadapter is not compatible with other accelerate lora, try to decrease the alpha of resadapter to 0.5 ~ 0.7.
