GPT Image 2.6 Sunburst Image to Image is OpenAI's editing model built for the tightest control: edits scoped precisely to the instruction, with subject and composition preserved across many rounds of revision. Up to 16 reference images; mask or markup (annotated overlay) local editing; a frame pipeline renders stills to a single GIF loop (SVG unavailable here). Quality has four tiers plus a separate reasoning_effort control.
