Ideogram 4.5 kept most of a room intact through 30 image edits as rivals drifted

ArtificialAnlys tested four models by having each edit its own previous output through 30 room-staging changes. It says Ideogram 4.5 kept most of the room intact, while GPT Image 2.5 Sunburst drifted most visibly. On small edits, it measured Ideogram 4.5 and FLUX 3 leaving at least 95% of the image essentially untouched; Sunburst left about a fifth unchanged. Nano Banana 2.1’s edits stayed local, but the rest of the image gradually darkened, it says.
