Do I need an account to use the studio?

Yes — generating requires an account so credits can be tracked, and new accounts start with free credits. Browsing and copying prompt templates never requires one.

What does an image cost?

A flat credit amount by resolution: 1K costs 10, 2K costs 20, and 4K costs 35 — the same on Flare and Sunburst, generation or edit. Failed generations are refunded automatically.

Is this the real GPT Image 2.5 Sunburst?

Yes. Generation and editing run the official gpt-image-2.5-sunburst and gpt-image-2.5-flare models, with Sunburst as the default.

Flare or Sunburst — which should I pick?

Draft on Flare when you want speed and exploration; finish on Sunburst when detail, text rendering, or keeping parts of an image unchanged matters. You can switch before every generation.

Can I edit a photo I already have?

Yes. Attach up to 16 PNG, JPG or WebP images, each under 30 MB, and describe the edit. References are sent in list order; use image 1, image 2 and so on in your prompt to explain each reference.

What sizes and formats can I generate?

Resolutions from 1K to 4K, thirteen aspect ratios from 1:1 and 16:9 to 21:9, and opaque or transparent backgrounds.

Can I keep editing a result?

Yes. Use Edit this image on any result and it becomes the reference for the next round, so you refine one instruction at a time without starting over.

Can I upload multiple reference images at once?

Yes. Add up to 16 reference images per request, each under 30 MB. Select or drop multiple files, add more, or remove individual images. Retry failed uploads; all references must finish uploading before generation. Reference count does not increase the credit cost per job; credits still depend on output resolution.

What reference image formats and sizes are supported?

Use JPEG/JPG, PNG or WebP. Each image must be smaller than 30 MB (30,000,000 bytes), with up to 16 images per request. Compress oversized files or convert unsupported formats before uploading.

GPT Image 2.5 Sunburst とは

ジェネレーターとエディター、一つのスタジオ

GPT Image 2.5 Sunburst is the precision tier of OpenAI's image models: it renders legible text, follows layered instructions, and edits an existing image while keeping everything you did not name unchanged.

The studio pairs Sunburst with Flare, the fast tier for exploration. Draft on Flare, finish on Sunburst — or send any result straight back in as the reference for the next round.

Every generation is one flat credit cost by resolution: 1K for 10, 2K for 20, 4K for 35. No per-model math, no surprises.

Sunburst is the default because editing precision is where an image tool earns its keep.

精密な編集、偶然ではない

Four capabilities that decide whether an image tool is a toy or a workspace.

Edits that hold still

Name what changes and what must not — Sunburst keeps the face, layout, and lighting you approved.

Text that renders

Posters, packaging, infographics: in-image typography comes out spelled exactly as written.

References that bind

Upload a product, person, or style frame and iterate without losing identity between rounds.

Output that ships

Up to 4K resolution, thirteen aspect ratios, and transparent backgrounds for production assets.

2つの入口、1つのスタジオ

Start from words or start from an image — the studio detects which and switches models for you.

Generate from a brief

Describe the scene, composition, mood, and any in-image text. Sunburst assembles it at up to 4K.

A menu board photograph for a coastal bakery, chalk lettering, morning light through the window.

Edit from a reference

Upload the image you already have, then state the change and the constraints. Only what you name moves.

Change the background to a marble counter. Keep the product, shadow direction, and label text unchanged.

一度に一つの指示で磨き込む

Every result can go back in as the next reference. Change one thing; earlier edits stay put.

Start from words

Describe your image or attach up to 16 PNG, JPG or WebP references, each under 30 MB. Attaching references selects editing. Explain each image’s role, what to change and what to preserve.
