Flare — the fast gear
Flare returns an image in about five to ten seconds. It is the everyday model: drafts, explorations, and anything you will iterate on. Cheaper per image, instant gratification. 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 GPT Images 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. Because both models share one balance and one history, moving between speed and precision costs nothing but a click. 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 quality tier. For print or storefronts, choose 2K or 4K; for drafts, 1K low is fine. 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.

GPT Image 2.5 Sunburst FAQ
What is the difference between Sunburst and Flare?
Both are GPT Image 2.5 models. Flare is the fast everyday option — about five to ten seconds per image at a lower cost. Sunburst takes longer and adds precision: sharper text, cleaner complex layouts, and edits that stay on brief. Draft in Flare, finish in Sunburst.
Is it free to try?
Yes — new accounts get free credits, and every model draws from the same balance. A 1K low-quality image costs 1 credit; higher tiers cost more. No credit card required.
What resolutions does it support?
From 1024px up to 4K (3840×2160 landscape), with quality tiers from low to max. Free accounts render up to 1K; paid plans unlock 2K and 4K. Transparent-background output requires PNG or WebP format. Landscape, portrait, and square formats are all covered by the fifteen presets.
Does it support transparent backgrounds?
Yes — choose transparent background with PNG or WebP output and subjects come out as clean cutouts, ready for storefronts, design tools, and compositing pipelines.
Can it edit my photos?
Yes. Upload up to 16 reference images, annotate the regions to change, and it edits only what you marked — the rest of the image stays untouched. Sketches count as references too, so a rough layout drawing plus a photo is a valid combination.
Can I use the images commercially?
Yes. Every plan, including free credits, allows commercial use of your generations — campaigns, merchandise, client work. You own what you generate; we never resell or reuse your assets. For client deliveries, keep the generation in your assets — it doubles as proof of origin.
How long does a generation take?
Typically 25–45 seconds depending on resolution and quality — longer than Flare’s five to ten seconds, shorter than a stock-photo hunt. The queue position and live timer are shown while you wait, and multiple renders run concurrently.
