GPT Image 2.5 precise image generation and inpainting for ads, products, and layouts
GPT Image 2.5 is OpenAI's image generation model family released in September 2026, the successor to GPT Image 2. It takes text and images as input and returns images, and it is built for edits that change only what you ask. In Neurohelper AI it appears in Image Master as GPT Image 2.5 (inpainting), so you can generate from a prompt or mask and repaint part of an existing image.
GPT Image 2.5 works alongside Nano Banana Pro, Midjourney 8.1, QWEN Image 3.0 Pro, and other image models in Image Master. Write ad copy in Chat Master, generate or repaint the visual here, and send the result to Video Master to animate it.
GPT Image 2.5 overview
What GPT Image 2.5 is built for
OpenAI's image models are chosen for control: they follow detailed instructions, handle text inside images well, and can edit an existing image instead of starting over. OpenAI offers GPT Image 2.5 in two variants, Sunburst for the highest capability and editing precision and Flare for speed. Neurohelper AI labels its integration as inpainting-capable; it does not state which variant it uses, so this page describes capabilities that apply to the family.
Edit only what you mark
Inpainting lets you change a background, swap an object, or fix a detail while protecting the parts of the image you did not mask.
Follow complex briefs
Long, structured prompts with layout, colors, counts, and copy are a good match for GPT Image models.
Render readable text
Headlines, labels, and short UI text in images are a known strength of OpenAI's image models. Proofreading is still required.
What's new vs GPT Image 2
What GPT Image 2.5 changes
OpenAI's documentation describes GPT Image 2.5 as the current generation of its GPT Image models. These are the points OpenAI documents publicly.
Two variants
Sunburst is described as the most capable option with the best editing precision. Flare is described as the fastest option for everyday generation.
Wider quality range
The API lists low, medium, high, xhigh, max, and auto quality levels, so speed and detail can be traded off.
Backgrounds and long prompts
The API documents transparent or opaque backgrounds and prompts of up to 32,000 characters, useful for cut-outs and detailed briefs.
How to use GPT Image 2.5 in Neurohelper AI
Generate or edit in three steps
There is no OpenAI API key or separate subscription. GPT Image 2.5 runs on your Neurohelper AI credit balance.
Open Image Master
Choose Create, then pick GPT Image 2.5. The current credit estimate is shown before you generate.
Prompt or upload and mask
Write a structured prompt, or upload an image and mark the area you want to change.
Review and iterate
Check text, product details, and faces. Make one targeted change per pass until the image is right.
Practical GPT Image 2.5 workflows
Three ways to use it in Image Master
The options shown in Image Master depend on the current integration. These are the workflows the inpainting label points to.
Generate from a brief
Write the full layout, subject, palette, and copy in one structured prompt.
Repaint part of an image
Upload an image, mask the area to change, and describe only that change.
Refine the result
Feed the best result back in and make one targeted change at a time.
Three marketing briefs · three creative briefs
Six briefs that show GPT Image 2.5's control
These are example prompts for GPT Image 2.5, not published outputs. Edit briefs assume you upload your own image and mask the area to change.
Generate an ad mockup with exact copy
GPT Image models handle layout and short text well. Describe the billboard, the product, and every word you want to see. The Neurohelper AI Advertising Studio uses the same approach for full ad sets.
View the prompt
Prompt: Photorealistic 16:9 photo of a large digital billboard on a busy city street at dusk. The billboard shows a fictional white running sneaker with coral accents, floating at a slight angle above a soft gradient from navy to coral. Headline in bold white sans-serif at the top left: "RUN THE CITY". Small line under it: "Ultralight. All day." Pedestrians below are slightly motion-blurred. No real brand logos, no other text.
Place a real product in a new scene
Mask everything except your product, then describe the new environment. Check that the label and shape are unchanged.
View the prompt
Mask: Everything except the bottle.
Prompt: Replace the masked background with a sunlit bathroom shelf of pale travertine stone, a small eucalyptus sprig to the left, soft morning window light from the right, and a gentle reflection under the bottle. Keep the bottle, label, cap, and proportions exactly as in the original. No added text.
Turn a short process into a clean visual
Numbered layouts with short labels are a good test of instruction following and text rendering, and they slot neatly into an AI marketing and sales funnel.
View the prompt
Prompt: Clean 4:5 infographic on a white background with three horizontal rows. Each row has a rounded coral number badge on the left (1, 2, 3), a simple flat line icon, and a short label in dark navy: "Create your account", "Pick a template", "Publish in minutes". Thin dotted line connects the badges. Title at the top: "Get started in 3 steps". Modern, minimal, generous spacing, no other text.
Change the season while keeping the composition
Mask the sky, trees, and ground. Describe the seasonal change and what must stay the same.
View the prompt
Mask: Sky, trees, road surface, and rooftops.
Prompt: Change the scene to a calm winter afternoon: light fresh snow on rooftops, bare trees with a dusting of snow, a pale overcast sky, slightly wet road with soft reflections. Keep the buildings, windows, cars, and camera angle unchanged. Natural photographic look.
Define a character once and reuse the description
Write a fixed character sheet into every prompt, then change only the scene. Feed the best image back in for later edits.
View the prompt
Prompt: Children's storybook illustration, soft gouache texture. Character: a small red fox named Pip with a cream chest, a short blue scarf, and a brown satchel. Scene: Pip reading a map on a mossy tree stump in an autumn forest, warm afternoon light, falling leaves. 3:2 landscape, gentle colors, no text.
Test lettering and layout in one image
Chalkboard menus combine typography, decoration, and short lists. Keep item names short and proofread every word.
View the prompt
Prompt: Square photo of a café chalkboard menu on a brick wall. Hand-lettered white chalk title "TODAY'S BREWS" with small decorative swirls. Three lines below: "Oat Flat White 4.50", "Cold Brew 4.00", "Chai Latte 4.80". Small chalk drawing of a coffee cup in the corner. Warm café lighting, slight chalk dust texture.

| Edit an uploaded photo | Yes, with a mask | Yes, including several images | No |
| In-app estimate | ≈5 credits | ≈5 credits | ≈2 credits |
Credit figures are Image Master in-app estimates from November 12, 2026 and can vary. Run the same brief on each model to decide.
How to prompt GPT Image 2.5
Write it like a design brief
GPT Image models reward structure. Describe the format, the layout, the subject, the style, and the exact text, in that order. For edits, say what changes and what must stay.
State format and layout first
Aspect ratio, background, and where each element sits help the model place things correctly.
Quote every word of copy
Put headlines and labels in quotes, keep them short, and say "no other text" to avoid extra words.
For edits, protect the rest
Mask tightly and add a sentence that lists what must stay unchanged: product, label, faces, angle.
When editing, make one targeted change at a time. Several small passes are easier to control than one prompt that changes everything.
Practical model selection
Where GPT Image 2.5 is especially useful
Strong uses
- ad mockups and banners with short, exact copy;
- replacing backgrounds around real products;
- infographics, step cards, and simple layouts;
- fixing or changing one part of an existing image;
- consistent illustrated characters described the same way each time;
- menus, signs, and posters with lettering.
Review carefully when
- long paragraphs of text must be perfect;
- the image must match a brand guide pixel for pixel;
- faces of real people or public figures are involved;
- you need a specific variant (Sunburst or Flare): Neurohelper AI does not state which one it uses;
- you want a painterly, highly stylized look that Midjourney may deliver faster;
- claims, prices, or legal text appear in the image without review.
