Image Models
Stable Diffusion Upscaler

In order to deploy the model you can use the identifier below:

  • Stable Diffusion Upscaler: sd-upscaler

This model was trained for 1.25M steps on a 10M subset of LAION containing images >2048x2048. The model was trained on crops of size 512x512 and is a text-guided latent upscaling diffusion model.

Your image must be smaller than 510px x 510px and if not, please add a width and height parameter to resize it. It does a 4x upscale so you will get a 2000x2000px image

You can follow this example of how to call the deployed endpoint:
