Thank you for continuing to support this product. It really is the most important Topaz product in my workflow.


Unfortunately, my first test came out a mess, with…well, check it out for yourselves.
Here’s the original (reduced for upload - original was 6MP):

And here’s the 6.3.0-enlarged version:

I’m not able to reproduce with your uploaded version. What settings are you using? Is the original a raw file?

Thank you. Works really amazing for me.

The original is a DNG. I’d have sent the original file, but this board doesn’t allow DNG files.

You would have to share through Dropbox or similar.

Hi - if you can please send me the original DNG through: Dropbox, confirm for me the scale factor & model used, and send me your log file from Help > File Logging > Gather logs for support. Please let me know if you’ve sent me something. Thank you!

I believe this is a processing issue, prob hardware compatibility related. Can you help talk with support team, and they will pull log and system information to debug.

I’m sure this is probably not the intended primary use of Gigapixel AI, but I’ve spent some considerable time on restoring old cartoons in version 6.2.2 from scans that were made in quite bad resolution from heavily worn out originals in in order of letting my kids enjoy my childhood heroes…
6.2.2 worked great, with the only caveat that “Very Compressed” often delivered better results than “Art & CG”.

Today I updated to 6.3.0 and the difference is like night/day, with "Art & CG actually delivering great results, and the all over experience is wonderful. Also - 6.3.0 does it’s thing a lot faster than the previous version.

Great job! (tipping my hat for the devs)


whenever i upload an image, the app just closes on it’s own after a few seconds, even happens with the tutorial

ok fixed it, i moved Topax Gigapixel to my D: drive a while back because of space issues, should make it so that updates go to were the app is install and not back in your C: drive

I just updated to 6.3.0. I must admit that I am really bluffed by the quality of the improvement of the “Standard” model as well as the new “HQ” model. I have not yet tested for faces on this new version. But already there, there is no photo. This version is the best so far. Good job devs.


I tried to uninstall the GAI beta and there is no uninstall.exe file. I then looked at the released version and it is also missing.
