GPT Image 2.5 Sunburst at a glance
Sunburst is the second GPT Image 2.5 model OpenAI ships, described as offering sharper details, more natural lighting and greater control across edits. In Shorz's own side-by-side tests it produced the sharpest scenes and the strongest same-face likeness from a reference — and even Flare at max quality didn't beat Sunburst at medium.
