Vertical Banding in MOSS-Image experiments

Key points

• I compared the SFT and Base models, tested swapping different transformer blocks, and narrowed most of the banding down to layers 37–41.1
• The fix is a LoRA that reverts just those layers to Base while keeping the rest of SFT intact.1
• Increasing resolution can also help with banding, although at higher resolutions it can turn into wider patterns instead.1
• More comparisons, ComfyUI workflows, and the full breakdown here (I should note that banding score isn't perfect by any means it finds stripes like in this image that shirt on the cashier on the base model so it only works to compare really close images relative to eachother):1

  Been digging into the vertical banding in MOSS-Image SFT.

  I compared the SFT and Base models, tested swapping different transformer blocks, and narrowed most of the banding down to layers 37–41.
