GPT Image 2.5
Continue your Image AI workflow
Quick answer
A GPT Image 2.5 generator turns a written prompt into a still image using OpenAI GPT Image 2.5 API models. This independent online workbench is built for creators, marketers, and design teams that need 1K, 2K, or 4K output without opening ChatGPT. Choose Flare for faster everyday drafts or Sunburst for tighter detail, then generate, review, and download. ChatGPT Images 2.5 is the consumer name for the same model family; the workbench is not the ChatGPT app.
The example stills show GPT Image 2.5 generator layout only. They are not confirmed GPT Image 2.5 outputs.

Examples
Each card pairs a visible prompt with the intended crop and a sample still. The images show workbench layout only; they are not claimed as live GPT Image 2.5 outputs.
This sample shows how a GPT Image 2.5 generator brief should name the subject, surface, lighting, and crop. It is a workbench layout example, not a confirmed GPT Image 2.5 output.
Use a GPT Image 2.5 generator thumbnail prompt to lock subject, contrast, and publishing crop before spending 2K or 4K credits. This image is a sample layout, not a confirmed model output.
A GPT Image 2.5 generator poster brief should reserve title space and name mood, camera, and palette. Review any generated lettering before publishing. This still is a sample, not a confirmed GPT Image 2.5 result.
Core controls
Keep the prompt, Flare or Sunburst, ratio, resolution, and preview in one GPT Image 2.5 generator workspace so you can check the setup before spending credits.
Start from an idea when you do not have a source file yet. The workbench keeps the prompt, model, ratio, and resolution next to the preview.
The GPT Image 2.5 generator accepts a text prompt up to 20,000 characters and returns a still you can review in the same session.
Input: a scene prompt with subject, lighting, crop, and use. Output: a 1K, 2K, or 4K image draft.
Match speed or precision without leaving the page. Both tiers share the same credit table in this app.
Flare is the default GPT Image 2.5 generator model for everyday drafts. Switch to Sunburst when labels, product edges, or layout need a tighter pass.
Input: Flare or Sunburst plus ratio and resolution. Output: one still at the selected size.
Set 1:1, 16:9, 9:16, 21:9, and other supported ratios before generation so the draft matches ads, posts, or posters.
This GPT Image 2.5 generator supports 1K, 2K, and 4K. Auto ratio is limited to 1K. Square 1:1 does not offer 4K.
Input: ratio and 1K, 2K, or 4K. Output: a still for 25, 40, or 65 site credits.
Inspect the still before you spend more credits or leave the workbench.
After a GPT Image 2.5 generator run, preview the draft in the same workspace and download it when the composition looks right.
Input: a completed still. Output: a downloadable draft you can later edit, upscale, or animate.
How to
Write one scene, choose the model and format, then review the still like a creative draft instead of a finished ad.
Name the subject, setting, lighting, camera, crop, and any readable text. A GPT Image 2.5 generator prompt works better when it describes one scene instead of a list of unrelated ideas.
Keep Flare for a fast first look. Switch to Sunburst when you need tighter product or layout detail. Pick a ratio that matches the destination, then choose 1K for tests or 2K/4K for review stills.
Check subject identity, lighting, crop, and any lettering. If Auto ratio is selected, stay on 1K. If you need 4K, avoid 1:1 and choose a supported wide or tall ratio.
Save the still, send it to the editor for a local change, upscale it, or animate it. Sign-in is required before generation uses credits.
Settings
Use this table to pick a GPT Image 2.5 generator model, ratio, and resolution that match the job.
| Setting | Available options | Best for |
|---|---|---|
| Model | GPT Image 2.5 Flare or GPT Image 2.5 Sunburst | Flare for everyday GPT Image 2.5 generator drafts. Sunburst for labels, product edges, and tighter composition. |
| Prompt | Text prompt, up to 20,000 characters | One scene with subject, lighting, crop, and any words that must appear in the still. |
| Aspect ratio | Auto, 1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16, 21:9 | Square ads, vertical social crops, wide posters, and cinematic stills. Auto is 1K only. |
| Resolution and credits | 1K / 25 credits, 2K / 40 credits, 4K / 65 credits | Cheap prompt tests at 1K, sharper campaign review at 2K, and large stills at 4K when the ratio allows it. |
Use cases
Use this workflow when the idea starts as words and you need a still before editing, upscaling, or animation.
Limits
Know the credit cost, ratio rules, and independence disclaimer before you treat a draft as production art.
The GPT Image 2.5 generator is an independent workbench that calls GPT Image 2.5 API models. It is not the ChatGPT app, not ChatGPT Images 2.5, and not affiliated with OpenAI.
The GPT Image 2.5 generator does not expose ChatGPT canvas markup, on-image comments, or official templates. Give those instructions in the prompt, or edit a generated still in the GPT Image 2.5 editor.
Guests can draft a prompt. Generation spends site credits after sign-in. 1K, 2K, and 4K cost 25, 40, and 65 credits. The GPT Image 2.5 generator does not offer an unlimited no-credit mode.
Auto aspect ratio is limited to 1K. Square 1:1 does not support 4K. Review faces, hands, tiny type, logos, and likenesses before ads or client delivery.
FAQ
Direct answers about Flare, Sunburst, credits, 4K, and how this independent tool differs from ChatGPT.
A GPT Image 2.5 generator turns a written prompt into a still image with GPT Image 2.5 Flare or Sunburst. It is an independent online workbench, not the ChatGPT Images 2.5 consumer app.
You can open the workbench and write a prompt without paying. Generating an image requires an account and site credits. 1K, 2K, and 4K currently cost 25, 40, and 65 credits.
Flare is the faster everyday GPT Image 2.5 generator tier. Sunburst is the precision tier for tighter detail. GPT Image 2.5 Flare and Sunburst use the same credit table on Grok Imagine; the difference is speed versus precision, not price.
A GPT Image 2.5 generator can create a 4K image when the selected ratio supports 4K. Auto ratio stays on 1K, and 1:1 does not offer 4K. Use 2K or 4K after the 1K composition looks right.
ChatGPT Images 2.5 is OpenAI’s consumer name. This GPT Image 2.5 generator uses the API model family through an independent site. It does not copy ChatGPT’s chat UI, Sketch tools, or official templates.
Next steps
