"AI-powered image post-processing" is only done in smartphones I believe.

Not anymore. DSLR makers are already using AI (in-camera neural network processing) for things like upscaling and noise removal. https://www.digitalcameraworld.com/reviews/canon-eos-r1-revi...

"The Neural network Image Processing features in this camera are arguably even more important here than they are in the R5 Mark II. A combination of deep learning and algorithmic AI is used to power In-Camera Upscaling, which transforms the pedestrian-resolution 24.2MP images into pixel-packed 96MP photos – immediately outclassing every full-frame camera on the market, and effectively hitting GFX and Hasselblad territory.

"On top of that is High ISO Noise Reduction, which uses AI to denoise images by 2 stops. It works wonders when you're pushing those higher ISOs, which are already way cleaner than you'd expect thanks to the flagship image sensor and modest pixel count."
