can you give us a little more information about new engines (training models)?
Like: how much better is a picture made with 5x vs 4x vs 3x.
Also: when is it worth to reprocess pictures done with an older version.
Things like that.
Thanx in A.

I can tell you I still like the picture quality in version 4.4.6. It has more detail than any of the later versions.
Thanks, this worked for me. Mac 10.13.6, CC 2019.
I certainly got the same result when I processed your original image in the latest beta. However, I tried the experiment of photographing four blue objects from around my house: two fabric, one painted wood and one shiny painted metal. The colour shift was not duplicated in any of them, so I suspect it relates to that particular shade/luminosity of blue.
You might want to raise a support ticket here:

That’s true, only high quality model in GPU mode gives those lines on the output image.

It’s like GAI introduced some sort of “raytracing” in the output image. 
I also noticed that ages ago (GAI also likes to add blue-ish tint at the edges of gray-scaled drawings sometimes), but it probably requires significant fight with the training model on devs side.
If you are sure that your trial version has not expired then you should contact Tech support from the main Topaz website. I noticed that in your task manager picture that Gigapixel is 3.3MB while I checked mine and it is 133 MB. So your computer is not running the full program.
Thanks for testing those! It’s an odd issue for sure, but given the older version doesn’t have it, surely something went “wrong” around v4.5.0
I’ll give the support ticket a shot, but given it was brought up back in 5.0.2 and wasn’t fixed yet… I’m not sure if they consider it a large enough issue to fix. 
It’s indeed visible - it might be a “colleague” of this blue-ish/green-ish artifacts I metioned - the negative color to the red-ish after all.
It’s even more horrible with Man-made model:
Thankfully, it’s not a colour that’s encountered much in the real world! The engineers often want samples to run through their AI learning machines, so offer them your’s.
Anyway, it’s easy enough to remove using any photo editing software. (I have to do this all the time with JPGs taken on my digital camera of 20 years ago, where there is almost always a cyan bias in the skies). Here’s what On1 achieved with one of your GP’ed images, by moving the purple slider toward the blue end of the spectrum:
Please support for 200,000+ thousand images.
Currently it is impossible to handle these large batches because it tries to load all the images for some reason. It should only load the image that you clicked on.
Maybe add another button. “Remove All Finished Images” or something like that. Or add a check box to allow that functionality. When you have a TON of images it would be helpful.
Thanks.

Something definitely happened to the models around v. 4.5. I often compare quality of image (by zooming in at pixel level) between 4.4.6 and 4.5 (and newer). Small details in the latter versions are more blocky, as opposed to finer details in 4.4.6. That difference still exists in the latest version.

Why have you removed the possibility to drop files into the window with the mouse?
It’s incredibly time consuming and annoying to have to add files via the open files dialogue, this will force me back to an older version if there’s no way around it.
I just dragged 3 images from Explorer onto the open application and it is OK:
You might need to provide more information, if it is open in plugin mode you will not be able to drag onto the application.
Realised that after I posted, I’m on win10.
Plugin mode?
I open the program from the start menu and when I then try to drop images dragged from explorer I get a forbidden sign (crossed over circle) and nothing more happens.
Plugin mode is such as if you open right clicking in explorer.
What images are you trying to open, it seems they are not supported?
OK, well that’s not the case, I run it from the start menu.
It’s completely standard jpg images, so nothing odd about them and I’ve tried with several different ones located in different places just in case and I’ve even tried running the program in admin mode but no difference.
And this post says it’s a problem that has been around before but the answer given there doesn’t give me any clues in how to fix it either.
That’s a system message that isn’t allowing you to drag and drop, have you rebooted or restarted the application?
I have seen this happen if the app is run from the last dialog on the install.
If you have restarted the app and or rebooted the pc and it is still happening raise a support request at the main website.
