MiniMax H3-Image open weights claim native 4K output — could it kill the upscale chain?
Jeric-2991 · reddit · 2026-11-14
A Reddit user vents about the perennial "upscale chain" problem in image generation: after nailing a good 1K/2K composition, running it through Hires. Fix or upscale nodes inevitably shifts the layout, melts skin pores into a plasticky look, and destroys clothing texture — making images look more AI-generated, not less.
They note the newly open-weighted MiniMax H3-Image reportedly supports 4K output with 4K as the default setting, and wonder whether this could finally skip upscaling entirely — asking if anyone has actually run it at 4K locally and whether consumer GPUs can handle it.
