I'd like to see the results in something like Wing Commander Privateer.

Try it yourself. Here is the demo: https://huggingface.co/spaces/prs-eth/thera

Tried it on this image[0] and it was blurry while still being pixelated.

That's an interesting example! Perhaps too out-of-distribution, though. For fair comparison with other methods, we used the DIV2K training set in our paper, which only comprises 800 images. Would be cool to train a version on a much bigger set, potentially including images similar to what you tried :)

I tried it on these, and the results were really great!

As other have mentioned, this models just puts emphasis on pixels and compression artifacts, so it's of not much use for improving old or low quality images.

I tried doing some pixelart->HD conversion with Gemini2.0Flash instead and the results look quite promising:

The images are however all over the place, as it doesn't seem to stick very close to the prompt. Trying to fine tune the image with further chatting often leads to overexposed looking pictures.

All the results are done with prompts along the lines of "here is a pixelart image convert it into a photo" or some variation there of. No img2img, LoRA or anything here, all plain Gemini chat.

It just looks like a strong sharpening filter.

It does not work with pixel art very well.
