In some places it looks almost as though they've taken the old tiles and fed them individually through some neural upscale/img2img diffusion.

The rocky coast[0] seems to change style slightly from tile-to-tile without much regard for how they fit together. The wall[1] has random artifacts, and equal trouble with tiling properly.

I think you could potentially avoid the tiling problem if you feed in a valid arrangements of tiles rather than each tile individually, and switch around the arrangement each diffusion step.
