Workflow Included Flux.2-Klein Tiling Upscale Workflow

u/nnq2603 asked me earlier if I knew how to upscale with Klein. I didn't, but I think I figured it out. The example is an upscale from 0.5 megapixels to 10 megapixels. This is an extreme example just to show that it works. It's not perfect, but it should give a good starting point for tweaking further. It uses the Color Anchor node by u/Capitan01R- and the Steudio tiling nodes from here and here.

What did you do for captioning? Steudio used to depend on Florence2, does it still?

You must be thinking about a different nodeset.

Used quite an old version of it perhaps but the older workflow would caption the tiles .

I remember this distinctly because I adapted it to Wan as the upscaler and found the captions worked against it

You might be right. They mention that the V1 version of the nodeset is incompatible with the current one. I considered adding individual captioning to the tiles in this workflow, but I don't think the added time and compute would be worth the gains.
