BTW. New model I've been testing https://imgsli.com/MTEzNzY

TBH it looks extremely odd. What use could there be of this one?

It does indeed.

As with the pixelity-faces model, this isn't gonna be useful on its own I think. However, given how hard it is to upscale faces, if this can do a decent job it can be used for patching in faces to otherwise working upscales.

It can also be used to create disturbing painting for use as background decorations.

What do you think about this?

This is DigiPaint/rebout_interp interpolation at alpha = 0.8, and I used Scattered (effect) when palettizing to produce some neat noise. Scaled to 2x with Bicubic better.

I was checking out new models in the database and noticed that the one called Spongebob v6 De-Quantize actually does a very good job on low-res stuff, except it makes the colours fade very noticeably. I interpolated it with rebout_interp at alpha = 0.8 and got some very decent results -- unlike any previous attempt I'm reluctant to scale down 4x output to lower res.

No image pre-processing was involved prior to upscale. The only downside is that I had to use GIMP's Auto Color Enhance to get the colours a bit less faded.

Here's some side-by-side comparison of a few full-size screenshots (aspect ratio not fixed):

I couldn't resist trying this out.

Both were done using the same SpongeBob model as in the post above. I used GIMP's Color Enhance (legacy) to brighten up colours because the model fades them quite noticeably. Downscaled to 2x and palettized using mtPaint.
