Hello @taylor.bishop,
I myself have difficulties with my own models sometimes because some inaccuracies occur at the interface between the GPU and the CPU.

Maybe instead of digging through kilometers of code in tensorflow, you’d better try adding another model to Gigapixel that will remove “banding artifacts” from the image, according to my concept:
This will be faster than fighting entropy in the form of machine errors 
. and adding a trained filter shouldn’t slow down the entire engine in Gigapixel 5 too much.
Best Regards,

PS.
All the time I admire you for your determination and new ideas (eg bypassing the problem of not scaling images in the “Filter” menu and designing the plugin as “Automate”). Very tricky!
