- Drafts from 2 credits
- Up to 4 images per run
- Up to 16 references
What's new in GPT Image 2.5
Which ChatGPT Images 2.5 upgrades does Flare bring?
OpenAI says Flare brings the ChatGPT Images 2.5 improvements in quality, editing, and speed to its API. These are the four you notice first. The pictures are examples, not side-by-side tests.
Reference photos
Your subject carries into a new scene
Upload a photo of a pet, a product, or a person and describe where it should go. Images 2.5 is better at keeping distinctive features, and Flare accepts up to 16 reference images per run.
Short copy
Short copy spelled the way you typed it
Signs, labels, and headlines come out right more often when they are short and in quotes. Long, text-heavy layouts are a better job for GPT Image 2.
Series
One character across a whole set
Describe the character once and ask for several panels in one image to keep the face, hair, and outfit together. Separate runs can still drift, so reuse a finished panel as a reference.
Drafts
Rapid prototyping: four directions from one brief
4 drafts at 1K low cost 8 credits in total, so you can compare whole directions before paying for a final. The grids below are example directions, not one model output.
Event poster
Compare poster styles at thumbnail size
Run one poster brief in several visual styles and judge the headline and the main subject at thumbnail size, where most people first see a poster. Only the style that still reads at that size is worth a higher-quality run; here, one plant-swap brief in four styles.
Product ad
Try ad routes while the product stays the same
Keep the product description fixed and vary only the ad concept, such as packshot, flat lay, illustration, or mascot. Check that the pack's shape, colors, and name match in every version; uploading a real product photo as image 1 holds them more firmly.
Mascot
Explore a mascot's look, then build on the winner
Describe the character once and try it as a badge, a toy, a sketch sheet, or a sprite to see which look fits the brand. Once one wins, upload it as a reference so new poses keep the same features.
How do you take a Flare draft to a final image?
Spend credits where decisions are made: cheap rounds while the idea is open, one careful run once it is settled. These habits follow OpenAI's GPT Image 2.5 prompting guide.
Do
Fix the brief, vary one line
Write the subject, purpose, format, and exact copy once. Change only the direction line between rounds, so you compare styles rather than prompts.
Draft in rounds at 1K low
Ask for up to 4 images per run. Composition, color, and layout already read clearly at this size.
Finish with the same prompt
Keep the prompt and aspect ratio of the draft you picked, then rerun it at high, 2K, or 4K.
Put exact copy in quotes
Quote headlines and labels, say where they sit, and spell brand names letter by letter.
Avoid
Start at xhigh or max
They cost many times more than low, and OpenAI notes that a higher setting doesn't guarantee a better result. Save them for a detail that still fails at high.
Ask for a transparent background
Oeneo AI doesn't offer that setting for Flare. Generate on a plain backdrop, then use Background Remover.
Rewrite everything to fix one detail
Upload the draft as image 1 and name the single change. If the rest has to stay exactly as it is, switch to GPT Image 2.5 Sunburst.
Fill the image with small text
Dense paragraphs can still come out wrong. Keep copy short and check it at 100% zoom.
Example prompt: "Poster for a Sunday plant swap in the park. Headline 'PLANT SWAP' in large letters at the top, a potted monstera in the center, portrait 3:4. Direction: 1970s bubble letters in orange and brown."
How many credits does each Flare quality level cost?
Each cell is the credit cost of one text-to-image result; the small line is an edit with one reference image, and every extra reference adds 2 credits per image. GPT Image 2.5 Sunburst costs the same at every setting. The Generate button shows the exact total before you submit.

GPT Image 2.5 Flare specs on Oeneo AI
OpenAI treats GPT Image 2.5 output above 2560×1440 as experimental, so 4K results can vary more than 1K and 2K.

What people ask before using GPT Image 2.5 Flare
What is GPT Image 2.5, and where does Flare fit?+
GPT Image 2.5 is the image model family OpenAI released on September 8, 2026; inside ChatGPT it appears as ChatGPT Images 2.5. The API offers two versions. Flare is the one OpenAI calls the default choice for most applications and its fastest model for high-quality everyday images. Sunburst is slower and built for precision editing. This page runs Flare.
Is Flare the model behind ChatGPT Images 2.5?+
OpenAI hasn't said which API model ChatGPT uses, and ChatGPT doesn't let you choose between Flare and Sunburst. On Oeneo AI you pick Flare directly in the browser, without a ChatGPT plan or an OpenAI API key.
GPT Image 2.5 Flare or Sunburst: which should I use?+
Both cost the same credits at every size and quality level on Oeneo AI, so the choice is about time. Start with Flare for drafts, exploring ideas, and everyday images. Switch to Sunburst when an edit has to leave the rest of the image untouched or a final file needs extra care on fine detail; OpenAI notes it takes longer. The Sunburst page compares the two side by side.
Is GPT Image 2.5 Flare better than GPT Image 2?+
OpenAI says Flare delivers higher-quality images than GPT Image 2, and its prompting guide suggests trying Flare first when a GPT Image 2 prompt already works for you. The quality names don't line up on price: a 1K image costs 16 credits at GPT Image 2 medium and 16 at Flare high. Keep GPT Image 2 for continuing a series made with it; the GPT Image 2 page compares both generations in detail.
Is GPT Image 2.5 Flare free?+
You can try it for free: new Oeneo AI accounts get 10 credits, valid for 365 days. A 1K image at low costs 2 credits, so that's about 5 drafts; a 1K image at high costs 16. Failed tasks are refunded, and images made on the free plan are public.
How fast is GPT Image 2.5 Flare?+
OpenAI describes Flare as its fastest model for high-quality everyday images, with 50% lower latency than GPT Image 2. We don't promise a fixed time: higher quality levels, 4K, long prompts, and busy periods all add to it.
How many reference images can I use with Flare?+
Up to 16 per run. Number them in the prompt and give each a job, for example "image 1 is the product, use image 2 only for the color palette." The first reference is included in the edit price; each additional one adds 2 credits per image. With Auto, the output follows the first image's aspect ratio.
Can GPT Image 2.5 Flare make 4K images?+
Yes. 4K output is up to 3840 px on the long edge: 3840×2160 at 16:9 and 2880×2880 at 1:1. OpenAI treats sizes above 2560×1440 as experimental, so settle the image at 1K first and check the 4K result at full size.
Does Flare support transparent backgrounds or masks?+
Not on Oeneo AI. OpenAI's API offers both, but this Workbench doesn't send them for Flare. For a transparent PNG, generate on a plain background and run Background Remover; for a local change, upload the image and describe the area in words.
Can I use GPT Image 2.5 Flare images commercially?+
Yes, on paid plans: subscriptions include a full commercial license, and the Lifetime plan covers personal commercial use (see Pricing). Images made on the free plan are public. Before publishing, check OpenAI's usage policies and the rights to anything you upload, such as logos or photos of people.
