gpt-image-2.5 promised richer detail than gpt-image-2 – we verified

the setup: two character sheets, each rendered once with gpt-image-2 and once with gpt-image-2.5, animated identically by bytedance's seedance 2.5

observations:

• @sama's mouth grille goes from five coarse slots to a fine louvre mesh
• sam's wrist gets a brass ring per finger joint and a segmented forearm – image 2 keeps a smooth plate
• sam's neck rings stack taller, with visible machined steps
• from behind, sam keeps individual hair strands and silver temples – image 2 flattens the back into one mass
• @finkd's ringlets separate with visible gaps instead of one denser cap
• mark's chain gets real volume and a bevelled-edge pendant
• mark's chest emblem glows larger, with light bleeding into the knit around it
• from behind, mark's ringlets stay separated all the way round

conclusion: every difference above lines up with openai's own claim for images 2.5 – richer textures, more natural lighting, better fidelity to reference detail – on the same two robots, not a new prompt
