Artificial Analysis tests four image editing models across 30 consecutive edits
Artificial Analysis tested GPT Image 2.5 Sunburst, Ideogram 4.5, FLUX 3 and Nano Banana 2.1 through 30 consecutive real estate staging edits, finding that Ideogram 4.5 preserved most of the room while the others drifted. Its leaderboard measures single edits, whereas this test fed each model its own previous output. On small edits, Ideogram 4.5 and FLUX 3 left 95% or more essentially untouched; GPT Image 2.5 Sunburst left about a fifth unchanged and drifted most visibly, while Nano Banana 2.1 edited locally but gradually darkened the image.
