I often manually remove disturbing fringing in photos blown up in AI or GP.
I know I am running into limitations of my lens at this point.
It would be great if there could be an AI de-fringing tool.
Just a thought.
It’d help if you could post a sample of what you’re calling “fringing”. The term, by itself, is too ambiguous.
look at the leaf edges on the right.
I use a blurring brush to get rid of the fringe in a case like this.
Knowing the camera info would help here, as would seeing the original image, pre-TPAI processing. If there’s EXIF info in the original file, it should resolve the “what camera and lens” question.
Frankly, there are a host of problems visible, making it hard to know which problems came from TPAI. For example, the blue edging on the leaves, also seen in some of the bird’s plumage, might be chromatic aberration originating in the camera. The darker area around the leaves, across the frame, could be TPAI, could be the blurring brush, could be… a number of things.
For comparison, here’s a barred owl, shot with a Sony DSC-RX10 M4. Post processing was PhotoLab 6 for cropping, lighting, color, noise reduction, then TPAI for enlargement and general cleanup.

Taking the original, as available here, and feeding it to TPAI 1.3.6, here’s a grab of TPAI at work. I don’t see any major flaws. Particularly as I think the original exposure, no offense meant, less than desirable.
FWIW, I use a rather dated laptop running Win10, and the grab is off an auxiliary 21" screen (i.e., nothing special).
