I read your post, well done. I sent the link to a friend.
Thanks! Glad you enjoyed it.
To be safe, please close the gigapixel program, and download the full installer, and install again. Thanks!
Yes I think so.

Follow up them they have a full collection of models.
It is a similar model downloading issue as some others have mentioned. Basically no model is found so no preview update or image save is valid. We will fix this but before done a few things can be done:
- if used in-app installer. close all the gigapixel programs. download the full installer, and install again.
if does not work, then - contact our support team by the chat button here https://support.topazlabs.com/. Ask them for the full collection of models.
help->install missing models
Note some users have reported downloading interrupted/stopped when downloading all the models. If that is the case, contact the support team as I mentioned here
I’m impressed with the new face recovery AI in 6.1. No issues installing and was able to download all the models in one go. Nice work Topaz.

My connection speed is about 50 mbit/s and this is the maximum in this small village. ~6MB/s download speed and from gigapixel servers come only 1MB/s. So it’s not good for me. More comfortable if they upload the full gigapixel pack with AI models. And download once.
you can try:

Or
Please chat with our support team from here https://support.topazlabs.com/. They have a full collection of our models and can send to you on request.
This is strange because I’m also experiencing this. When switching models or scale it says “loading…” for more than 5 seconds, especially with GPU, and sometimes the program hangs and shows “does not respond” for a very brief moment before finally starting to process.
It was much more responsive with the previous versions, even though there always was a “loading…” delay, but not that long and without the unresponsive window.
For information I’m on i7 9700K and GTX 1070Ti.
Denoise and Sharpen also have a significantly longer waiting time when switching models with GPU than it is with CPU.
Also I feel like I have some models in double. Is that normal that the Gigapixel models folder is 16 Go by doing the updates from February 2022 to now ?

The picture doesn’t have a whole face in it as shown in the upper right corner. Can’t expect the AI to recognize it correctly.
Gigapixel often causes unwanted color shifts, especially the Low Resolution and Art & CG models. If you are using GAI as a Photoshop plug-in, it puts the new upscaled image in a “gigapixel-layer” over top of the original background, which is scaled up using Photoshop’s regular Bicubic interpolator.
So here’s a stop-gap measure to use until Topaz gets this color shift fixed: To get my original colours back I set the blend mode of the gigapixel-layer to Luminosity. That allows the original colors to show through but with the new details. It’s not perfect, but usually pretty close and better than having clobbered colors.

Exactly. It seems that model loading was much faster in the older versions of GAI. This slowness discourages me from trying out the different models on my images. BTW, this is without the face refinement option.
Face recovery is good, however fine hair strands become thick and chunky. Hoping this will get fixed.
I think hair still mostly relies on the main models which is very hit and miss, especially the Standard model. Its somewhat frustrating that the Low Resolution model often does hair better but then loses detail in the rest of the image.
I have contacted the support about it.
I don’t know if this will help but try using a VPN ( I use Cyberghost) and connecting to a server in the USA. This my bypass the slow circuit. The problem is not with Topaz servers which are fast. I have a 400 Mb/s download internet and I can download gigapixel 6.1 in less than a minute.
The installer download is fast, but what @dency01 is talking about is that model download from inside Topaz software is extremely slow.
I also have a 400 Mb/s download speed so the .exe downloads at 50 MB/s, but the models will download at 6 MB/s at great maximum. It sometimes even go as low as 1 MB/s.
It is actually intended and if you ask support they will give you faster links for model download.
Just tried updating a different computer in-app from v5-something, failed (very fast connection BTW):
Uninstalled the older version and downloaded the full app from the top of this thread. I notice it is asking me to put the app directly in Applications (Mac), whereas the older version was in Applications>Topaz Labs LLC>Topaz Gigapixel AI
Fresh version seems to be working fine, now I get to download models again
