I was quite disappointed that the Photoshop generative fill stuff insists on running on Adobe's servers rather than locally. So however good it is, there are many of us who will never use it.
Yeah-- I can only assume it's to ensure a consistent experience and to not disperse the model openly. If you have the model running locally on people's computers, it limits who can use the generative AI and opens up a ton of headache around customer support. Again, I don't work on this, but I'm familiar with generative AI and what it takes to run.
