Explore what GPT Image 2.5 can do

GPT Image 2.5 brings closer attention to detail, editing instructions and reference images, from photographic textures to focused edits and ongoing creative work. Three official examples show these capabilities in practice.

Natural light and richer textures

Bring lighting, materials and composition together for more nuanced photographic detail.

Official example: a sailor repairing a net. The prompt combines skin texture, worn clothing, soft daylight and a film-like finish.

More precise local edits

Change a specified object while aiming to preserve the surrounding composition, lighting and other elements.

Official example: replace white chairs with wooden chairs while keeping the camera angle, room lighting and floor shadows.

Consistent characters across scenes

Use a character reference to carry appearance and visual style into a new scene.

Official example: continue a forest hero’s picture-book story. A new scene helping a squirrel retains the character’s outfit, facial features and watercolor style.

BLANC remains readable on the label in this result. Paper and fabric textures changed, along with reflections and edges of the bottle. Larger dimensions do not guarantee faithful packaging details; check them before commercial use.

A bundled sample processed through this tool’s existing AI workflow. Previews are only reduced and compressed to WebP, with no added blur or sharpening. Each image keeps its own proportions; this is not a 100% pixel comparison. The full PNG is the file returned by the service.

Product photos, bigger possibilities

Take a closer look at textures, materials, and packaging. Prepare larger images for your storefront, catalog or next campaign.

The blue roofs and white buildings remain recognizable, but wall textures, strokes on the sea and some architectural details changed. Use this example to assess large-screen display, without assuming every original brushstroke will be preserved.

Wallpaper use cases

Turn a favorite image into wallpaper

Upload landscape photos, illustrations or abstract artwork for use as static wallpaper. Match the image to your screen’s aspect ratio, then choose 2K or 4K to help keep your subject in frame.

These examples explain sizing and screen fit, not measured before-and-after results. 4K is experimental. The dimensions shown are request targets; actual output depends on the AI result.

16:9 landscape

Desktop wallpaper

Example source
1920 × 1080 px
4K request target
3840 × 2160 px

A good fit for scenery, architecture and landscape illustrations. A 16:9 screen is more likely to preserve the full composition. Check foliage, building edges and sky gradients for visible artifacts after processing.

9:16 portrait

Phone wallpaper

Example source
1080 × 1920 px
4K request target
2160 × 3840 px

Use a portrait photo or illustration. Taller phone screens may still crop the sides, so preview the subject’s position and leave room for the lock screen clock and home screen icons.

21:9 landscape

Ultrawide wallpaper

Example source
2520 × 1080 px
4K request target
3840 × 1632 px

Use wide landscapes or panoramic compositions. Target dimensions follow the source ratio and round down to multiples of 16. Choosing 4K does not always mean 3840 × 2160 output, and does not extend a standard landscape image into a panorama.

Supports static JPG, PNG and WebP images up to 10 MB, with aspect ratios from 1:3 to 3:1. Animated wallpapers are not supported. The tool does not crop to fit your screen or extend the image. AI may alter textures, text and details; check the downloaded dimensions and preview on your target screen.

How do credits work?

01

Get credits

Monthly plans renew automatically. Credits are added after each confirmed payment and expire at the end of that billing period without rolling over. Cancel from your account. One-time packs do not renew and their credits never expire. Applicable taxes are shown at checkout.

02

Use as you go

Each 2K image costs 8 credits; each 4K image costs 18 credits. Both resolutions use the same credit balance.

03

No charge for failures

Credits are deducted only when an image is successfully generated. Failed requests and images that exceed size limits cost no credits.

Estimated cost per image assumes you use all credits in your plan. Unused credits increase your effective cost per image.

Frequently asked questions

Which image formats are supported?

We support static JPG, PNG, and WebP images up to 10 MB. AI editing may change transparency; check the result before use.

Will upscaling affect image quality?

Results depend on the source. Basic resizing adds pixels but does not recover lost detail. AI enhancement can introduce different textures, so always inspect the result.

How large can I make an image?

2K fits within 2560 × 1440 and 4K within 3840 × 2160, with width and height reversed for portrait images. Dimensions follow the source aspect ratio and are rounded to multiples of 16. 4K is experimental; actual output depends on the provider.

Are my images stored?

Images are uploaded to this server and sent to the configured AI provider for enhancement. Results expire after 24 hours. Expired uploads and outputs are deleted during the next scheduled cleanup. Images created while signed in are available only to your account. Credits belong to your signed-in account. See the pricing section for purchase availability and eligibility.

Is AI enhancement available now?

Upscaling requests AI enhancement and returns the AI-generated image as delivered without cropping or resizing. AI may change details. Examples shown before processing are illustrative.

Can I upscale images for print?

Check output pixel dimensions against your print size and target PPI. More pixels do not guarantee more real detail. Inspect at 100% and make a small test print first.

How do I receive credits?

Credits arrive after payment is confirmed. Each 2K image costs 8 credits and each 4K image costs 18 credits. Failed jobs cost no credits, and downloads are free.

Do credits expire? Can I cancel?

Monthly plans renew automatically. Credits are added after each confirmed payment and expire at the end of that billing period without rolling over. Cancel from your account. One-time packs do not renew and their credits never expire. Applicable taxes are shown at checkout.

Do failed jobs or repeat downloads cost credits?

Credits are deducted only after a successful result. Failed requests and images that exceed size limits cost no credits. Downloading the same result again is free; each new successful generation is charged, even if you use the same image and resolution.
