Miniature world, one landmarkA whimsical handcrafted miniature diorama of London built around Big Ben. A cosy tiny world at its feet — cobbled street, red phone box, lamp posts, a newsstand, benches, autumn trees. Soft daylight, shallow depth of field, a small brass plaque reading "LONDON" at the front.
Concept render, machinery that readsA photorealistic concept render: a giant white-and-black police rescue mech wading down a flooded city avenue, towing two orange lifeboats of evacuees by cable. Rain, grey daylight, traffic signals and shopfront signage still legible above the waterline. Documentary framing, no motion blur on the machine.
Photography, not photo-ishA candid smartphone photograph of a young woman walking slowly down a quiet tree-lined residential street at golden hour. Medium-length chestnut hair in a loose half-up style, an oversized shirt and a shoulder bag, an iced coffee in one hand. Backlit with a slight lens flare, natural skin texture, no retouching.
Same person, four anglesA four-panel character sheet of the same woman on a seamless neutral studio backdrop: front, three-quarter turn, full profile and rear view. Terracotta wide-leg trousers and a matching top in every panel, soft even lighting, identical framing and proportions across all four.
Editorial ad, type inside the frameA vertical luxury advertisement shot in a dark emerald studio. An oversized gold-cased wristwatch fills the right of the frame with a model in a green field jacket leaning against it at the left. The masthead "TIME" runs across the top in gold serif capitals and the brand line "AURELON — SWISS MADE" sits small at the lower left. Editorial lighting, no other text.
A whole landing page, one frameA complete desktop landing page for a creative design studio, written in Simplified Chinese, drawn flat and front-on with no perspective: a navigation bar, a hero with a headline and a photograph, a three-up services row, a case-study grid, a call-to-action band and a footer. Bold flat blocks of blue, yellow and red, a real type hierarchy, legible small print. No lorem ipsum.
Typography, and nothing elseA black-and-white typographic poster. The wordmark "MODEL.STORE" set very large at the top, the strapline "NINETY-ONE MODELS. ONE BALANCE." beneath it, then an eight-line spec list in small monospaced type. Newsprint texture, one column, generous margins. Every line legible, no decoration.
Figures, captions, folioA single page from a Spanish-language physics textbook, chapter seven, on electromagnetism. Two numbered figures with captions, three short sections of body text, one boxed equation, a running head and a folio. Warm off-white paper, one accent colour, eight-point caption type that stays legible.
Merch sheet, eight pins, one styleA hyper-realistic enamel pin collection on a dark textured board, eight separate pins overlapping in a loose collage. Polished gold-metal outlines, glossy hard-enamel fill, subtly raised edges and one soft specular highlight per pin. A portrait pin carries the name "MIRA" and a small tag below it reads "CREATIVE". The same light on all eight.
Six panels, one characterA one-page black-and-white manga about space development, six panels read right to left. Screentone shading, hand-lettered speech balloons, a wide establishing panel at the top and a close-up at the bottom. The same character in every panel. No colour.
Travel poster, headline and deckA premium travel poster, portrait. A whitewashed Santorini street descending to blue domes and the caldera at sunset. The headline "SANTORINI" in gold serif capitals at the top, "Greece · Island of Dreams" beneath it, four lines of deck copy at the lower left. Editorial photography, warm evening light.
Small type, eight times overA vintage travel postage stamp representing Japan: Mount Fuji and a pagoda as the focal point, surrounded by a bullet train, cherry blossom, a torii gate and a beckoning cat. Perforated edges, aged paper, a franking mark reading "JAPAN POSTAGE" and a small caption under each element. Muted printed-ink palette.

What got better in GPT Image 2.5
OpenAI’s announcement lists four. Here is what each one changes once your images are a job — and all four are live in the generator above.
Try these on your own prompt
The printGPT Image 2.5
01Reference fidelity
Your subject survives the trip
Hand it a reference and your subject arrives in the new scene still recognisable — same face, same label, same finish. The product in the ad stays the product in the box.

02Precision editing

Change one element and the composition, subject and brand treatment around it stay put. Higgsfield's Head of Product: "how well it understands what not to change."
Prompt: "make the bed" — everything else in the room is untouched

03Multi-turn consistency
Edit chains hold up longer
Long chains hold together where GPT Image 2 came apart. A developer in r/codex: "after 2–3 edits the image was often unusable… This seems much better now." Improved, not solved.

Six jobs people are actually using GPT Image 2.5 for
Six jobs, and the sentence that makes each one land. Every card loads a working prompt into the generator, settings already dialled in.
QUOTE THE TEXT · HD vs ULTRAPosters and packaging
Layouts where the headline and the small print both have to read. Quote every rendered word, then compare HD against Ultra before you commit.
DRAFT AT STANDARD · RE-RUN AT HDInfographics and diagrams
OpenAI names infographic accuracy and layout as a specific gain in 2.5. Check the labels, not the look — draft at Standard, re-run the winner at HD.
IMAGE TO IMAGE · TICK FACE & IDENTITYPortraits from a photo
Carry a face into a new era, wardrobe or style. Identity, pose and expression hold; only what you named changes.
THINK · KEEP LIGHTING & FRAMINGIterative product edits
Change one thing — the chairs, the label, the bottle — and the light, the framing and everything you didn't name come back exactly as they were. Sunburst is the tier built for the fourth revision, not the first.
REFERENCE FIRST · THEN RESTATE ITStoryboards and sequences
Build one reference frame first, then name its defining details again in every new scene. The repetition is the instruction, not padding.
STRUCTURE REFERENCE · not styleSketch to finished image
Draw the layout, then let the render fill it in. Say the sketch is structure, that the perspective holds, and that nothing new is added.
Half of these are a pair — what went in, and what came back. The prompt on a card is the recipe for that job rather than the caption for that frame, and no frame on this page is used twice. Want the whole tool rather than one prompt? text to image writes a picture from a sentence, image to image changes one thing in a picture you already have, and sketch to image turns a drawing into a finished render.

What OpenAI still lists as unsolved in GPT Image 2.5
Precise text placement can miss. Character and brand consistency across separate generations can still drift. A higher quality tier does not guarantee a better result — OpenAI says so, and so do we before you spend Max credits.

Where GPT Image 2.5 lands on the Arena leaderboards
Sunburst first, Flare second, on all three boards. Both sit on the toggle above, so the top-ranked one is a press away, not an upgrade.

- Sunburst #1#1Sunburst#2Flare#3Next best

1,381 → 1,421
One published figure for the release · not one per board
Elo moved from 1,381 to 1,421 — a solid incremental win, not a new category. A launch-thread commenter put it better than any marketing page: "going from 1,381 to 1,421 isn't 'destroying' the benchmark."

The one number that surprised people
GPT Image 2.5 at Standard costs a quarter of GPT Image 2's medium tier. The founder of 12ui.com: "about 2x faster and 1/2 the cost of the old 2 medium."
Each row says what changes for you rather than which model wins in the abstract. Sample images, prompts and per-item scoring live on the comparison pages, linked from each row; the generator is the same one at the top of this page.
What the GPT Image 2.5 image generator costs here
OpenAI prices by token rather than by image: an everyday 1024×1024 at medium costs $0.0132 upstream, the same for both models.
Same credits either way — yearly just costs less per month
Or buy credits once and spend them slowly
No subscription, no renewal. Packs cost more per credit than a plan and the reason is on the label: they last twelve months, where plan credits expire at the end of the month.

GPT Image 2.5 image generator: the questions people ask
Sixteen answers, and two of them do not flatter us. Cost, the free tier, commercial rights, and what the receipt under each image is for.
Is GPT Image 2.5 out?
How much does GPT Image 2.5 cost per image?
medium, $0.053 at high, and $0.211 at max, based on OpenAI's $30 per million image output tokens. Cost scales with resolution and quality, not a flat per-image fee. Batch requests are half price. Here, a standard 1K image is 6 credits — roughly $0.05 on Pro.Does GPT Image 2.5 still have the checkerboard artifact? The part other pages skip
Clouds and gradients — still visible on GPT Image 2, Flare and Sunburst alike. "It's still really noticable in clouds and plants." (r/OpenAI, 14 upvotes)
Grass, foliage and hair — mostly unchanged, though some report better hair on Sunburst. "It seems to still have that checkerboard pattern in my tests." (r/ChatGPT, 25 upvotes)
Between lines of dense text — the worst case, on both models. "The checkerboard effect behind text and other patterns is horrendous." (r/codex, 19 upvotes)
Three things help, and they are OpenAI's guidance rather than our finding: HD and above on flat subjects, PNG output, and the fewest edit rounds you can get away with.
Is the checkerboard the same thing as a fake transparent background?
Neither is a watermark. OpenAI embeds C2PA metadata and an invisible watermark; neither is a visible texture, and nobody — including us — adds a pattern to your image.
How do I know if I'm using GPT Image 2.5 and not GPT Image 2?
gpt-image-2.5-flare or gpt-image-2.5-sunburst) along with quality tier, size and generation time, and you can open the raw API response to check it yourself.Flare or Sunburst — which should I pick?
Is GPT Image 2.5 free? Do I need a ChatGPT account?
Is there a GPT Image 2.5 AI image generator I can use online, without installing anything?
Is there a watermark?
Does GPT Image 2.5 support 4K and transparent backgrounds?
3840×2160 and 2160×3840; anything above 2560×1440 is flagged experimental by OpenAI. Transparent backgrounds are native on both 2.5 models and the panel's Background chip asks for one — it needs PNG or WebP, since JPEG has no alpha channel, and it is a Starter unlock. A transparent run travels by the direct API rather than the gateway we use by default, whose record for these two models lists auto and opaque only.The catch is the model's, not ours: asked for transparency it will sometimes paint a grey-and-white checkerboard instead — a picture of transparency rather than transparency. Open the alpha channel and check, and put "no checkerboard" in the prompt.Can I use GPT Image 2.5 images commercially?
Why do my edits change things I didn't ask about?
Is GPT Image 2.5 better than Nano Banana Pro?
Can it keep the same face across edits?
Why is ChatGPT's image generation slow or limited for me?
Is GPT Image 2.5 the same as GPT Astra or Gemini 2.5 Flash Image?
