GPT Image 2.5 Sunburst — images that follow the brief to the letter

Sunburst is the most capable model in OpenAI’s GPT Image 2.5 line. It creates and edits images, sticks closely to instructions, renders crisp text in the frame and changes an existing photo exactly as described. A frame usually takes about 25 seconds, and the price depends on the quality level: from 3.3 ₽ on low, which is the default in limko.

from 3.3 ₽ per image

Sunburst’s strengths

  • Strict instruction following: the model pays attention to the caveats and conditions of a long prompt.
  • Precise edits by description — only what you asked for changes, not the whole frame.
  • Crisp text in the frame: cover headlines, signage, captions on mockups.
  • Several input images — a frame can be assembled from different photos.
  • Transparent background when you ask for it in the prompt — handy for logos, stickers and design elements.

Quality levels and price

The level is chosen before the run and sets the price of the frame. Low is the default — use it to test an idea, and switch to the higher levels for the final.

QualityWhen to choose itPrice per image
low default: test the idea, composition and prompt from 3.3 ₽
medium intermediate versions for sign-off ≈ 8.7 ₽
high a finished image ready to publish ≈ 23.7 ₽
xhigh a high-stakes frame where every detail matters ≈ 46.3 ₽
max the model’s highest level ≈ 92.5 ₽

Sunburst or GPT Image 2.5 Flare

The GPT Image 2.5 line has two branches. GPT Image 2.5 Flare is the fast one: it handles a steady stream of drafts, and low there costs 3 ₽. Sunburst is the senior one: it follows the conditions of a long prompt more precisely and edits an existing photo more carefully.

Sunburst is the pick when there are many conditions and redoing the work is costly: an edit with a list of things that must not be touched, a mockup with lettering, a frame assembled from several photos. Look for the idea on low or in the fast branch, then finish the final on Sunburst at high or above.

Nano Banana Pro and Qwen Image 3 also handle lettering well: for an important layout, compare them with Sunburst on the same prompt.

How to run Sunburst in limko

  1. Choose the model

    In the image generator, find GPT Image 2.5 Sunburst in the list of models.

  2. Attach photos if you are editing

    For an edit or a composite, one or several images; for an image from scratch, text is enough.

  3. Describe the task

    The result first, then the conditions as separate sentences. Put the text for the frame in quotes.

  4. Set up and run

    Aspect ratio (1:1, 3:2, 2:3, 4:3, 3:4, 16:9 or 9:16), quality level and number of variants — up to four. The price is shown on the button, and the result is saved to your history.

Prompts that play to Sunburst’s strengths

Write in your own language: the model understands the description without translation. Conditions are easier to list as short sentences, and the text for the frame goes in quotes.

Edit with conditions

Replace the jacket with a navy sweater and make the background light gray. Do not change the face, hairstyle, pose or lighting; keep the watch on the wrist.

Cover with a headline

Podcast cover: a vintage microphone on a dark green background, with the large headline “Talks That Matter” at the top. Flat graphics, two colors, lots of empty space.

Transparent background

Laptop sticker: a smiling cactus in a pot, thick white outline, bright colors, transparent background.

Frequently asked about GPT Image 2.5 Sunburst

How is Sunburst different from GPT Image 2.5 Flare?

Can I edit my own photo?

Yes: attach the photo and describe the edit in words. You can also upload several images and combine them into one frame.

Can Sunburst make a transparent background?

Yes, if you ask for it in the prompt — for example, “on a transparent background”. That is handy for logos, icons and stickers.

Can I write the prompt in my own language?

Yes, OpenAI models understand it without translation. No VPN is needed to use it.
