OpenAI image generation · independent guide
GPT Image 2.5 is OpenAI’s image-generation and image-editing model family. It includes Flare for fast everyday generation and Sunburst for detailed generation and precision-focused editing.
Independent third-party guide and generator. Not affiliated with OpenAI.
Model overview
GPT Image 2.5 creates and edits images from text and image inputs. Flare focuses on fast everyday generation, while Sunburst targets workflows needing more detail and tighter edit control.
Use this guide to compare the models, review matched tests, and try both through an independent interface.
Two models, different priorities
Start with Flare for speed. Choose Sunburst when detail and edit control matter more. For production work, test both with the same prompt and settings.
Official role · speed
Use Flare for fast drafts, everyday creative work, and higher-volume generation.

| Requirement | Practical starting point | What to verify |
|---|---|---|
| Fast drafts and variations | Flare | Acceptance rate and latency |
| Everyday image generation | Flare | Detail at the selected quality |
| Detailed or demanding edits | Sunburst | Unwanted changes outside the edit |
| Subject or product preservation | Test Sunburst first | Identity, geometry, labels and text |
| Final production choice | Compare both | Cost per accepted output |
Selection rule: Test both models with the same prompt and settings before you commit.
Matched benchmarks
We run both models with the same prompts, inputs, sizes, and quality settings. Review every result—including misses—along with latency, cost, text accuracy, and edit consistency.
TEST 01
Compare both models with the same prompts and settings.
TEST 02
Track identity, clothing, lighting, composition and unintended changes over repeated edits.
TEST 03
Measure spelling, punctuation, numbers, layout, duplicates and readability inside images.
24 unique cases
Cases are deduplicated by prompt and input images. When the same case appears across model or comparison pages, it is shown here only once.
Practical workflows
Create from a prompt, edit an existing image, guide the result with references, add text, or export a transparent asset.
01
Describe the subject, setting, composition, lighting and intended visual treatment.
02
Request one focused change and restate the identity, geometry, layout or lighting that must remain.
03
Assign each image a role: person, product, outfit, style, composition or background.
04
Quote required wording, specify its location and ask for no extra text. Inspect spelling, numbers and legibility.
05
Use PNG and inspect alpha edges around hair, glass, fabric, shadows and reflections.
06
Use focused follow-up instructions while checking identity, objects, text, layout and lighting after every round.
Prompting system
Name the photograph, poster, diagram, ad, illustration or interface you need.
List the subject, materials, colors, framing, light and background.
For edits, state the one change and then list every detail that must stay the same.
Write the exact wording in quotation marks, set its location and request no extra copy.
Check requested edits, unrelated areas, text, identity and product geometry.
TASK:
Edit the supplied image.
CHANGE ONLY:
Change the blue shirt to a black jacket.
PRESERVE:
The face, facial features, hairstyle, expression, body shape, pose, camera angle, framing, background and lighting.
DO NOT ADD:
Extra accessories, text, logos or watermarks.
OUTPUT CHECK:
Confirm only the shirt changed. Report any visible drift in identity, framing, background or lighting.
# Review the complete output before use.

Clear answers
GPT Image 2.5 is OpenAI’s model family for generating and editing images from text and image inputs. It includes GPT Image 2.5 Flare and GPT Image 2.5 Sunburst.
OpenAI announced GPT Image 2.5 Flare and Sunburst on September 8, 2026, as recorded in its official API changelog.
No. gptimage2-5.io is an independent third-party generator and information website. It is not affiliated with, endorsed by or operated by OpenAI.
Flare is designed for fast, high-quality everyday generation. Sunburst is intended for detailed generation and precision-focused editing.
Yes. Upload an image and state what should change, along with the identity, object, text, layout, camera and background details that must remain unchanged.
Yes. Supported formats, file-size limits and the number of references depend on the provider or interface. Assign every reference a clear role in the prompt.
You can request preservation of identity, product geometry, materials, labels and layout, but you should inspect every result, especially after repeated edits.
It can generate text inside images. Keep the copy short, quote it exactly, specify its location and always review spelling, punctuation, numbers and legibility.
Yes. Select a transparent background and PNG output, then check difficult alpha edges around hair, glass, fabric, reflections and shadows.
No. Credits bought here cannot be transferred to OpenAI, and official OpenAI API billing does not use this site’s credit amounts.
Start with Flare for fast everyday generation and prompt exploration. Test Sunburst when preservation or precision-focused editing matters more than turnaround time.
Commercial use depends on the website terms, applicable law and the rights associated with your prompts, uploads and requested content.
