Choose Flare when speed and a polished first pass matter most. It is the practical default for campaign images, product concepts, social covers, and layouts that need natural light, rich texture, and readable structure.
Choose Sunburst when the review standard is detail first. It is suited to intricate materials, premium editorial visuals, complex diagrams, and prompts where small structural errors are expensive.
Both variants are part of the same GPT image generator workflow. Use Flare when you need a fast AI photo generator for campaign concepts or social images; use Sunburst when the brief depends on fine texture, photorealistic AI portraits, or careful reference-image editing.
A simple comparison workflow is to keep the prompt, ratio, resolution, and quality the same, then compare subject accuracy, layout fidelity, texture, and the amount of cleanup needed. Save the stronger output as a reference for the next iteration.
Try both variants in the GPT Image 2.5 generator. GPT Image 2 remains available when a saved project explicitly requires the earlier model. If you need prompt structures before comparing the variants, use the GPT Image 2.5 prompt guide.
A practical GPT image generator comparison
Keep the subject and creative brief stable, then review one variable at a time. For a product photo, check shape, material, label placement, and background edges. For an AI portrait, check skin texture, expression, hair detail, and lighting continuity. For a reference edit, check which original details remain consistent after the requested change.
