Take the approved idea through its most demanding decisions. Sunburst is the precision-focused GPT Image 2.5 option for intricate compositions, controlled edits, premium product work, and references that carry real creative weight.
GPT Image 2.5 Sunburst is selected by default. Create one image from a prompt and optional references here, or open the batch workspace when you need Variations, CSV, or Products.
Inside GPT Image 2.5
GPT Image 2.5 Sunburst is the high-control model in the family, built for work where instruction fidelity and the finish of the final image matter more than the quickest turnaround.
Some briefs fail when one small detail drifts: a product changes shape, a face loses identity, the lighting contradicts the scene, or a carefully approved layout comes apart during an edit. Sunburst is intended for these denser tasks, where several visual requirements need to survive in the same result.
The BulkGen generator gives Sunburst the same flexible workspace as Flare, including multiple references, one to four outputs, standard or custom dimensions, five quality tiers, background behavior, and selectable file formats. The difference is when you reach for it: use Sunburst when the image is carrying final-stage product, identity, typography, material, or composition constraints.
Sunburst is most useful after the concept is clear and the remaining work depends on handling many details together.
Build stationery, posters, presentation visuals, packaging studies, and other compositions where type, ornament, spacing, and imagery share the frame. Supply exact copy and a clear hierarchy, then proof the lettering before delivery.
Use separate images to define the person, product, environment, material, or visual language. A prompt that assigns each source a job gives Sunburst a clearer map of what it must retain and what it may reinterpret.
Coordinate pose, wardrobe, setting, lens, light, palette, surfaces, copy, and negative space in one direction. Sunburst belongs on briefs where simplifying those requirements would weaken the idea.
Use the premium path for hero imagery and final campaign assets that depend on convincing materials, coherent illumination, deliberate composition, and careful treatment of brand or product references.
A precise edit begins by defining the locked parts of the source. Identify the face, product, pose, framing, text, or palette that must remain, then isolate the requested change so Sunburst does not have to guess where creative freedom begins.
Lock the subject's identity, expression, pose, wardrobe, and framing. Change only the background to an intimate evening reception, preserve the existing depth of field, and introduce warm practical lights whose reflections and shadows agree with the original photograph.
The premium model makes sense when missed instructions create more rework than a longer generation step.
Create material-rich product scenes, key visuals, and packaging directions where the object, setting, light, and brand cues must read as one considered image.
Carry a selected concept toward final delivery while maintaining its palette, composition, subject treatment, graphic language, and intended level of polish.
Replace or restyle a specific region of an existing image while explicitly protecting the identities, objects, proportions, and framing that make the source valuable.
Write the prompt in the order you would review the result: objective first, protected requirements next, then composition and finish.
Objective + source roles + locked details + allowed changes + layout + viewpoint + illumination + materials + copy + delivery use
Produce a vertical hero image for a luxury skincare launch using the supplied amber bottle. Preserve its silhouette, cap, label colors, and logo position exactly. Set it upright on rain-dark charcoal stone in a close three-quarter view, add cool dawn backlight with a narrow warm rim, realistic mist and water beads, and leave generous quiet space above for campaign copy. Keep the materials photoreal and the art direction restrained.
Put protected faces, products, proportions, poses, framing, labels, and brand colors in a dedicated sentence before describing any transformation.
Tell the model which reference supplies identity, geometry, surface, palette, composition, or mood. Do not make it reverse-engineer your reference set.
Use concrete position, scale, depth, lens, crop, viewing angle, and negative-space instructions so you can judge whether the output followed the brief.
Resolve the big decisions before selecting Max. Premium rendering is most valuable after the subject, layout, and art direction already deserve a final-detail pass.
The same three-step workflow works for one-off ideas and structured batch production.
GPT Image 2.5 Sunburst is selected when the page loads. Write one prompt, add supported reference images when needed, or open the batch workspace for larger jobs.
Describe the subject, context, composition, style, and constraints. Then choose the supported ratio and resolution for GPT Image 2.5 Sunburst, adding reference images only when the model allows them.
Submit the job, compare the GPT Image 2.5 Sunburst results, and regenerate with targeted prompt changes. Completed work is available in history for later review and download.
The current BulkGen controls let you balance creative intent, delivery format, rendering effort, and credit use for each GPT Image 2.5 request.
| Setting | Available choices |
|---|---|
| Quality | Low, Medium, High, XHigh, Max |
| Canvas size | 15 aspect ratios from 1:3 to 3:1, plus supported custom dimensions |
| Background | Auto, opaque, transparent |
| Output format | PNG, JPEG, WebP |
| Images per request | 1–4 images |
| Reference images | Up to 16 images across the request |
Both GPT Image 2.5 models can generate and edit inside BulkGen. Choose by production stage: Flare is the faster workbench for finding the direction, while Sunburst is the precision tool for resolving it.
| Model | Reach for it when | What you are choosing |
|---|---|---|
| GPT Image 2.5 Flare | You are finding the idea, filling a content queue, or testing several viable directions | A faster creative loop instead of the family's most exacting final pass |
| GPT Image 2.5 Sunburst | The direction is approved and reference fidelity, edit control, or finish carries more weight | More time and credits in exchange for the premium model's added capability |
Generation settings can improve the attempt, but they cannot replace a coherent brief, direct comparison with the references, or accountable human approval.
Sunburst is not the economical choice for every sketch. Use Flare for broad exploration and bring Sunburst in when greater control can save meaningful revision work.
Reference fidelity remains probabilistic. Compare faces, logos, labels, product geometry, and other protected details directly with the originals before approval.
A long prompt can still contradict itself. Rank important requirements, remove competing directions, and divide an overloaded edit into separate passes when necessary.
The quality selector in BulkGen includes Low, Medium, High, XHigh, and Max. The upstream Auto setting is not currently exposed here.

Capabilities are based on official vendor material and the API documentation used by the BulkGen integration. App-facing controls may intentionally expose a smaller supported subset.
Open the generator above with GPT Image 2.5 Sunburst already selected, write your brief, choose the delivery format, and move from one idea to a reviewable result in the same workspace.
