How we compared the models

This pair comes from a published comparison dated 11 September 2026. Its method specifies the same prompt, 1:1 format, 2K resolution and Standard quality for both models, with one result each. We imported the published 1200 × 1200 WebP previews without cropping, resizing or retouching. These examples were not generated through our API.

These are two individual visual examples. They do not measure speed, reliability or cost per approved image. The brief below is a summary, not the original prompt or a request recorded on our API.

GPT Image 2.5 Flare

GPT Image 2.5 Flare: A pastel 3D cloud character for an app illustration
Flare gives the cloud a fairly level base and a broad, symmetrical body. The lower edge has stronger pink, lavender and blue colour. The eyes and cheek circles are separated clearly, so check how those details read at the final icon size.

GPT Image 2.5 Sunburst

GPT Image 2.5 Sunburst: A pastel 3D cloud character for an app illustration
Sunburst gives the silhouette a tilted, rounded shape and blends the pastel colours more softly into the white surface. The smile and cheek placement differ. Use the complete outline to judge whether it fits the illustration slot in your app.

Open model: GPT Image 2.5 Sunburst

Cost for this scenario: 1:1, 2K

The published run used Standard quality. That is not a verified match for the quality settings of our API routes, so no like-for-like charge is assigned to these images. Current starting prices and supported parameters remain in the model table below.

Which model to try for your task

Choose an empty-state illustration

For this brief, choose between the more level, symmetrical cloud and the tilted, softer silhouette. Inspect each at your actual display size; the full-size preview alone does not tell you which works better in a compact interface.

Keep a character consistent across screens

Approve one character as a reference and review later variations against its outline, face and palette. These text-only samples do not test character consistency across a sequence.

Budget your own API request

Use the model page to choose your supported settings and inspect its quote. Standard-quality examples from another service do not establish the price, waiting time or output of our route.

Frequently asked questions

What can GPT Image 2.5 Flare do that GPT Image 2.5 Sunburst cannot?

Their published capability labels match. This does not establish identical output quality or behaviour; compare the accepted input values and test the same brief.

Do GPT Image 2.5 Flare and GPT Image 2.5 Sunburst take the same parameters?

They share 4 parameter names. Check each model’s allowed values, required fields and defaults before reusing a request.

Can I switch between GPT Image 2.5 Flare and GPT Image 2.5 Sunburst?

Both use the same API Stock API key and prepaid balance. Change the model field, then check the target model’s input schema, supported values and output before sending the request.
