I was so incredibly tired of trying to get an actual "usable" result through a generative image model. Its always impressive results, but the fact that they're just pixel blobs, makes them entirely unpractical.
I have no idea how an agent would leave a watermark in Klad. It's got no agent inside, and every mark that an agent made would have possibly been made by a human as well. I guess they would have to really specifically target Klad to be able to make a watermark happen...
