Flare — the fast gear
An image every five to ten seconds at the lowest per-image cost on the platform. It is the default for drafts, variations, and anything you will iterate on — including every free-credit render.
ExampleWhat is GPT Image 2.5 Flare?
It is the speed-focused variant of ChatGPT Images 2.5. The model generates and edits images from text prompts and reference photos in about five to ten seconds per render — fast enough that iteration stops being a budget decision and becomes a workflow. At the draft tier both variants feel instant; the heavier sibling only stretches its legs at 2K and above.
It shares the GPT Images studio with everything else here — sketches, annotations, up to 16 reference images, and full version history. Both models draw from the same credit balance, so exploring at Flare speed and finishing at Sunburst precision costs nothing but a click. Drafts, finals, and references live side by side.
It is built for creators who think in iterations: social teams testing ten thumbnails before lunch, designers sketching directions on a client call, writers prototyping covers mid-draft, and anyone whose best idea shows up at version seven. If volume drives quality, this is the model.

Flare vs Sunburst
Same studio, two gears — Flare is the fast one.
Sunburst — the precision gear
It takes twenty-five to forty-five seconds per image and adds what final deliverables need: fine typography, layered graphics, reference-accurate portraits. Explore here, finish there.
Same prompt, both models — drag the handle to compare. At draft settings both returned in about ten seconds in our test; at 2K and high quality, Sunburst runs about a minute while Flare stays near ten seconds.

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 — Flare 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 locked to the fast model. Nothing else about the studio is locked.
Keep settings light
Drafts belong at 1K and low quality — one credit each, seconds per attempt. Save 2K and 4K for the version that gets shipped. Queue position and a live timer show while each render runs.
Generate, judge, repeat
Review the result, pin annotated edits, or feed it back as a reference. Iterations are the point; every version stays in your assets.
Three habits for fast iteration
- 1
Change one thing per render. Prompt A/B tests read cleanly when a single variable moves — swap the lighting word, not the whole sentence, and compare the pair. The version strip keeps both attempts side by side for the verdict.
- 2
Draft at the cheapest tier. Low quality at 1K costs one credit and lands in seconds; only the approved direction earns a higher tier.
- 3
Promote the winner. When a draft is right, regenerate the same prompt in Sunburst for crisp text and fine detail — the handoff keeps every reference and annotation, and nothing about it is manual.

Character exploration
Pose and costume variations at conversation pace — silhouette first, polish later.

GPT Image 2.5 Flare FAQ
What is the difference between GPT Image 2.5 Flare and Sunburst?
Both are GPT Image 2.5 models with the same input — prompts, sketches, and up to 16 references. Flare renders in five to ten seconds at the lowest cost; Sunburst takes longer and adds precision for fine text and layered graphics. Both share the same balance, the same history, and the same form.
Is it free to try?
Yes — new accounts get free credits, and this is the cheapest way to spend them: a 1K low-quality render costs 1 credit. Failed renders refund automatically, so experiments never cost you. No credit card required.
Is Flare lower quality?
It is the same model family tuned for speed. Drafts and everyday images are indistinguishable; where Sunburst pulls ahead is fine typography, intricate materials, and multi-layer layouts — the final-deliverable tier. If you cannot tell them apart at arm’s length, you needed Flare.
How fast is it really?
Five to ten seconds for a typical 1K render in our tests — about four times faster than the precision tier. Queue position and a live timer are shown while you wait, and multiple renders run concurrently.
When should I switch to Sunburst?
When the draft is approved. Client deliverables, print, packaging, and anything with headline text earn the slower render; everything before that moment belongs at Flare speed. The swap keeps your prompt, references, and annotations intact.
What resolutions does it support?
From 1024px up to 4K with five quality tiers — though the fast workflow is happiest at 1K, where renders land in seconds and cost a single credit. Paid plans unlock 2K and 4K. Landscape, portrait, and square are all covered by the fifteen presets.
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.
