@kerravonsen @phil @maxleibman yep. I had a picture rejected for a book cover because I used Pixelmator's Super Resolution to get it to print resolution. That's a very light edge enhancement trained on public domain images that runs locally.
In the end I had to upscale with the Lanczos algo, which produced a far inferior result, and it's all because "AI" was mentioned in marketing by Pixelmator before the term became utterly tainted. It's just a local neural network. I used one in 1991!
