What is GPT Image 2.5 Sunburst?
GPT Image 2.5 Sunburst is OpenAI's most capable image model, released on September 8, 2026 alongside Flare. It is built for work that has to be exact, like campaign creative and product imagery, and takes a little longer per image.
In late September 2026 it ranked first on LMArena for both text-to-image and image editing. In our tests it kept a sneaker's shape, stitching and logo through a recolor, and the same man recognizable as a chef, a hiker and an executive.
What it does best
Product edits that keep the product
Change the colorway and keep the sole, the stitching, the shape and the logo.
The same person in new scenes
One studio headshot in, the same face out as a hiker, an executive or a chef. Useful for brand stories, team pages and characters.
Dense layouts and real data
Charts with the numbers you give it, packaging with every claim in place, slides that keep their hierarchy.
Same prompt, three models
One try per model with Fiddl's settings, nothing retouched. Times are from our run on October 3, 2026.
Perfume product shot
Same label text on all three; the bottle shape and splash differ.
Candid cafe portrait
Three natural, believable candids from the same sentence.
Bilingual ramen menu
Japanese and prices correct on all three.

First tries with GPT Image 2.5 Sunburst, nothing retouched. Tap one to see its prompt.
Check the lettering before you publish
In our two-reference fragrance ad Sunburst kept the man's face and the bottle's label exactly, but spelled the new headline "AURELE" instead of "AURELLE". Spell unusual names letter by letter in the prompt and read every word before you use the image; one follow-up edit fixes it.
Sunburst or Flare?
Use Sunburst when precision is the point: a product that must not change shape, a face that must stay the same, a layout full of exact copy. For drafts and high-volume variations Flare is faster and costs the same on Fiddl, so many people draft with Flare and finish with Sunburst.

Prompting tips that work
Condensed from OpenAI's image prompting guide and our own tests.
- Number your reference images and give each a job: "image 1 is the product, image 2 is the person".
- Write "change only" the one thing, then list everything that must stay: face, label, shape, camera angle.
- Quote every word of copy exactly, and spell brand names letter by letter.
- Make one change per edit and check it before the next; restate what must stay if something drifts.
- Draft ideas with Flare, then finish the keepers with Sunburst.

Questions, answered
What is GPT Image 2.5 Sunburst?
OpenAI's most capable image generation and editing model, released on September 8, 2026. It takes text and up to 16 reference images on Fiddl and makes images up to 4K in 11 aspect ratios.
Is Sunburst the best image model?
On LMArena's public leaderboards in late September 2026 it ranked first for text-to-image and for image editing, and it was tied for first on Artificial Analysis's text-to-image arena. Scores for new models are still preliminary, and for a particular style another model can suit you better.
Why is Sunburst slower than Flare?
OpenAI says Sunburst trades longer generation times for an extra level of precision. In our test it averaged about 40 seconds per image, against about 27 for Flare and about 99 for GPT Image 2.
How much does Sunburst cost on Fiddl?
The same as Flare: about 25 images with the $10 Starter pack and about 125 with the $42.50 Studio pack, from $0.28 per image on the largest pack. 4K images cost a little more. During the launch, code GPTIMAGE20 takes 20% off any pack until November 2, 2026.
Can Sunburst keep my face or my product the same?
That is what it is best at. Give it the photo, say what should change and list what must stay. Results are very close but not pixel-identical, so check the details before you publish.
Can I combine several images into one?
Yes. Add up to 16 reference images, number them and say what each one is for, for example the product from image 1 in the hands of the person from image 2.
Can I use Sunburst for free?
There is no free tier for Sunburst on Fiddl. Packs are one-time payments from $10 with no subscription.
