Tile upscale controlnet with Z-Image-Base? Has anybody achieved good results?

This Reddit thread from r/StableDiffusion discusses community experiences using ControlNet Tile upscaling in combination with Z-Image-Base, a Stable Diffusion base model. ControlNet Tile models are often misunderstood as simple upscalers — they are actually structural detail reconstructors that analyze the local semantics of image tiles, ensuring the diffusion process stays consistent with local context while adding new high-frequency details. The thread likely explores user-reported results, settings, and compatibility challenges when pairing the Tile ControlNet workflow with Z-Image-Base, as a known downside of this method is that too much detail can be added, potentially changing the image in a way that is no longer a faithful scale-up of the original.
