The cheese pattern and the green teacup pattern after it are obviously AI generated. The weird curve of the wedges, the fuzzy edges to the cheese holes, the artifacting around the edges of the teacups, the fact that neither is a perfectly repeating pattern. It's 100% AI, even if the font may not be.

Even more obvious, look at the detail on the frame - it’s a unusual pattern that doesn’t repeat as you would expect.
