No artifacts? What are you talking about? All of those scenes are utter nonsense. Upper left, nothing to note, it’s super generic. But the upper right is a fall themed picnic… in the spring because of the Sakura blossoms. And nothing in the “picnic” makes any sense.

Bottom right, does that look like a believable scene to you? Cause, there’s way too much fruit, not enough workspace, the pans on the wall in the back make no sense, and the pie is something out of a nightmare. And we come at last to the worst of the bunch. I call it… something to do with string. Cause what they’re making is indecipherable. Voodoo dolls? Creepy, tiny yarn balls with red tubes? And the background is “vaguely Christmas”, complete with ornament on a branch, connected to nothing

And yeah, I do see artifacting. It’s most obvious in the kitchen scene. The “grapes” are mostly collections of blocks. Blocks that intrude into the line dividing the top from the bottom. The “box” in the picnic scene was another example.

Also, the focus is faked. Things in the foreground are more in focus than what should be nearby objects. Clear fields of view wander from focus, to out-of-focus, to back in focus.

The compression artifacts and low resolution do a good amount to hide the problems, but there’s nothing believable about these images. They’re clearly ai generated, with all the defects that implies.
