Flare — the fast gear
Flare is the everyday model for drafts, explorations and iterative work. Both models use the same resolution-based credit cost: 1K costs 1 credit, 2K costs 4 and 4K costs 6. Free accounts and every paid plan can use both.
The precision half of ChatGPT Images 2.5
GPT Image 2.5 Sunburst, built for detail
The heavier of the two GPT Image 2.5 models — it trades a few extra seconds for sharper text, cleaner layouts, and edits that stay on brief. Upload a reference, draw a layout, or just describe the shot.

ExampleWhat is GPT Image 2.5 Sunburst?
It is the precision-focused variant of ChatGPT Images 2.5. The model generates and edits images from text prompts and reference photos, producing output from 1024px up to 4K — trading longer generation time for extra fidelity: more natural lighting, richer textures, cleaner complex layouts, and tighter edit control. It handles the same sixteen-image reference input and transparent backgrounds as its faster sibling.
It shares the ZingPix studio with every other tool here — sketches, annotations, up to 16 reference images, and a version history that never loses a pass — so precision work stays in one place. Both models share one balance and one history, so switching between speed and precision does not itself submit a task; every new generation or edit still uses the credit cost shown before you run it. Drafts, finals, and every reference you upload live side by side, so nothing about the workflow changes when you switch models — only the output does.
It is built for brand and marketing teams whose campaign typography must be legible, e-commerce sellers whose product shots get zoomed, illustrators running reference-faithful character and environment passes, content teams producing thumbnails for A/B tests, and print designers whose headlines must be spelled right. If the output is the product, this is the model.

Sunburst vs Flare
Same studio, two gears.
Sunburst — the precision gear
It takes longer per image and adds exactly what detailed work needs: fine text, layered graphics, reference-accurate portraits. When the draft is approved, switch gears. Free accounts and every paid plan include it.
Same prompt, both models — drag the handle to compare.

Rule of thumb: explore in Flare, finish in Sunburst — both live in the same form above.
How to use it
The model selector is already set — Sunburst is the default on this page.
Describe or attach
Write a prompt, draw a composition sketch, or drop up to 16 reference images — the form on this page is the full studio. The model selector is the one thing removed: it is set to the precision model and stays there.
Tune the output
Pick an aspect ratio and resolution. Use 2K or 4K for print and storefronts, or 1K for a quick draft. Reference images count toward the same sixteen slots as sketches and uploads.
Generate and refine
Review the result, pin annotated edits on it, or feed it back as a reference. Every version stays in your assets.
Three habits for better results
- 1
Draft in Flare, finish here. Explore composition and wording at Flare speed and price; when the direction is set, regenerate the approved prompt in the precision model for the final asset. The two models read the same references and annotations, so nothing is lost in the handoff.
- 2
Name the details you care about. “Crisp serif headline”, “visible fabric weave”, “sharp reflections” — pointed instructions get followed; vague ones get average treatment. One precise sentence beats a paragraph of vibes.
- 3
Use references for identity. A portrait or product photo plus “keep the face identical” anchors the subject; multi-reference consistency does the rest.
