Hi-Res After Txt2Image

[invisiblestrangler]

Hi!

I want to know if it is possible to do Latent hi-res after an image has been generated? The reason I ask this is because I want to only apply hi-res on good images to save time and computation. For example, I generate 300 txt2img images and only hi-res 50 of them.

No, I am not thinking about upscaling it. I want to add details like hi-res. Thanks!

As far as I know, the current version of hires is just an upscale and then an img2img pass over the upscaled image with the original prompt at a low denoising strength. You could do the same.

Generate the images you want without HiRes fix.

Then, copy and assign the seed of the image you want to use the HiRes Fix, use the same prompt, scale, steps, sampler, and size, and generate again from txt2img applying the HiRes fix option.
