LM and I have had conversations about Topaz Photo AI and I did bite the bullet and pay to upgrade to the latest version.
The current version, 3.5, has AI Denoise that is on par with what Lightroom Classic does and which is functionally instant, unlike the ~10-second-per-image-at-best-but-only-if-the-Adobe-runs-on-the-right-GPU deal Lightroom does.
I'm also getting pretty great results with the "Recover Faces" function. I fully realize that this is a program making up detail that isn't really there, but my test image was a group photo taken on ~30 year old 1.2MP camera and I have to say this is maybe the one place where I truly see AI image manipulation doing great work. Every one of over a dozen people in that pic was recognizable once I did a 4x enlarge and put it through the recover faces function.
I'm impressed enough to put in a good word here.
