GPT Image 2.5: Flare for quick iterations, Sunburst for precise edits

A client asks for a background change. The returned image looks attractive, but the packaging and its lettering have changed too. For a working layout, that matters more than dramatic lighting. The interesting theme in GPT Image 2.5 is controlled, sequential editing: developing an image without losing details already approved.

Two variants for different jobs

On September 8, 2026, OpenAI introduced ChatGPT Images 2.5 and the GPT Image 2.5 Flare and Sunburst API models. Flare targets quick iterations; Sunburst targets more precise edits with longer generation times. That is the provider’s positioning, not an independent comparison we performed.

Give model selection a specific purpose

Imagine building a series of product cards. While exploring the idea, different compositions are useful. After the packaging is approved, the job changes: variations must preserve that identity. Our editorial conclusion is to identify the stage of the work before choosing a tool.

For this hypothetical project, keep “exploration” and “approved” folders. The first allows substantial departures; each revision in the second is compared with a reference. That organisation is useful regardless of the model name and helps prevent an attractive but incorrect draft from replacing an approved one.

Try one controlled revision

An editorial sample brief is: “Change the background to a bright studio. Preserve the packaging’s shape, colour and lettering, the object’s position and the crop.” It is not a guaranteed recipe; it defines the expectation before generation.

Compare the result beside the source. If it works, save a separate version and move to the next task. If not, note which details changed unexpectedly. One clearly defined revision tells you more about a working tool than a collection of unrelated attractive outputs.

What to compare between candidates

• How long did the whole cycle take, including review?
• Did the required source details survive?
• How many repairs remain before handing over the layout?
• Does it serve the actual brief, beyond looking good in a feed?

Measure the route to an accepted layout

Our view is to assess the journey to an accepted result, not just one generation time. A quick draft may be ideal for exploring composition. An approved product needs predictable revisions. Check VIZURAI’s current catalogue and generation button for actual availability and the price of a run.
