An image model for everyday visual creation and rapid iteration
GPT Image 2.5 Flare is an image generation and editing model focused on generation speed. It is suitable for turning creative briefs into advertising visuals, interface concepts, and product scene images, and can also adjust colors, backgrounds, and composition using reference images. It is better suited to creative workflows that explore directions first and then refine selected results; Sunburst in the same series focuses on high fidelity and precise control, and can be used for tasks with higher requirements for detail preservation.
Clarify capacity, input/output, and invocation methods before choosing a model.
Creation methods
Text-to-image generation; editing reference images with text instructions
Reference image input
The editing endpoint accepts a single image URL or an array of up to 16 URLs
Number of generations
Platform n is 1–10; only 1 image is supported when returning b64_json
Aspect ratio settings
auto or WIDTHxHEIGHT; explicitly specified dimensions must be multiples of 16, with the longer side not exceeding 3840
Common quality controls
auto is used by default; low, medium, and high are quality options listed by the endpoint and are used only when supported by the selected invocation variant; different levels are not guaranteed to produce different results
Image delivery
Output formats can be png, jpeg, or webp; results can use url or b64_json
Task modes
Returns image results synchronously; supports asynchronous callbacks via callback_url
The quantities, dimensions, and formats above are invocation rules for this platform's endpoint and do not represent the model's native specifications or guarantee the effects of all parameter combinations.
Core Capabilities

Explore visual directions from creative briefs
Flare is suitable for organizing subject, scene, lighting, color palette, and composition requirements into comparable image concepts. When creating marketing assets, you can explore different backgrounds and visual styles around the same theme, first select the most suitable direction, then continue refining the chosen image instead of locking into a complex final version from the start.
Use reference images to describe editing goals
When editing, you can submit product photos or existing designs and clearly state the subjects, angles, and layouts that need to be preserved, as well as the colors, environments, and backgrounds you want to change. Multiple reference images can be used to express different visual requirements, but you should explain the role of each image to avoid treating conflicting compositions or styles as simultaneous goals.
Integrate image delivery into applications
Generation and editing each use dedicated image endpoints, and the output remains an image rather than an editable design project. Applications can receive image links or use Base64 image data; for tasks that require longer waits, asynchronous callbacks can be used to separate task submission from asset ingestion, making subsequent review and delivery easier.
Use Cases
Start with specific tasks to find where the model can make an impact.
Visual alternatives for marketing campaigns
Enter the campaign theme, target audience, product features, and placement format to generate a set of poster or social media image alternatives. Use text to specify the subject position, background mood, and copy space separately, then select compositions suitable for placement. Before delivery, add accurate brand elements and check whether the text in the image and product appearance meet requirements.
Interface and landing page concepts
Enter the page objective, module order, brand colors, and desired interface style to create visual concepts for landing pages or application screens. It is suitable for discussing layout mood, illustrations, and information hierarchy; the deliverable is a concept image, while component dimensions, interaction states, typography specifications, and functional pages still need to be completed during design and development.
Product scenes and storyboard sketches
Use product photos or scene descriptions as input to explore seasonal backgrounds, lighting, and promotional scenes, and also create video opening frames and storyboard sketches. Prompts should specify the camera angle, subject position, and details to preserve; after obtaining static images, pass them into subsequent design or video production workflows for continued use.
How to choose this model
Choose based on task complexity, input materials, and expected results.
Choose Flare for speed; compare Sunburst for detail
When tasks involve everyday visuals, creative proposals, and multi-round direction exploration, Flare's speed-oriented approach better aligns with the work objectives. If you need to preserve product structure as much as possible, make fine adjustments to local content, or require higher consistency with reference images, you can compare GPT Image 2.5 Sunburst. It is recommended to use the same materials and instructions, and judge the trade-off by usable generated images rather than model names.
Distinguish series versions from public invocation variants
GPT Image 2 is a related previous-generation model, and its example results should not be directly regarded as Flare's results. gpt-image-2.5-flare and gpt-image-2.5-flare:official should also be used as different invocation IDs. They share Flare's basic positioning, but their parameters and billing must be configured separately; do not assume that all request formats are exactly the same merely by adding a suffix.
Get started
From a small-scale task to formal integration.
01
Prepare tasks and materials
Clarify the objective, required inputs, and output requirements, and use real business examples as a starting point.
02
Try it in the API testing area
Open the trial page, confirm the parameters supported by this entry point, then submit a small-scale task to review the results.
03
Integrate according to the API documentation
Keep the complete model ID, use the request format specified in the documentation, and confirm billing rules on the Pricing page.
Usage boundaries
Before formal use, understand output quality and capability scope.
Being speed-oriented does not mean every task can be completed immediately, nor does it mean a single generation is ready for publication. Complex layouts, dense text, and strict brand guidelines require item-by-item review; in particular, poster titles, prices, labels, and logos should receive final correction in design tools.
Reference image editing is not lossless pixel replacement. When changing backgrounds or colors, subject textures, edges, and details may also change; product structures that must be strictly preserved should be clearly specified in the prompt and compared item by item with the original image. If necessary, use a model that places greater emphasis on fine control.
Specified dimensions must also meet rules such as total pixels of 655,360–8,294,400 and an aspect ratio no greater than 3:1. Do not treat an aspect-ratio string directly as the pixel value for size; meanwhile, b64_json supports only single-image returns, and image links are preferable for batch results.
Frequently Asked Questions
Answers to common questions about using gpt-image-2.5-flare.
What are the main differences between Flare and Sunburst?
Flare focuses on generation speed, making it suitable for everyday image creation, creative alternatives, and quick revisions; Sunburst focuses on high fidelity and fine-grained control. If the task emphasizes product details, reference image consistency, or complex editing, compare Sunburst first; if the main goal is to explore visual directions, you can start with Flare.
How should I submit existing product photos?
Use /openai/images/edits, explicitly set model to gpt-image-2.5-flare, and submit a single image URL or an array of URLs through image. In the prompt, clearly specify what to preserve and what to change, for example, keep the product angle and outline while changing only the background and lighting.
Can I generate multiple images at once and return image data directly?
The range for n is 1–10, which is suitable for generating alternatives around the same brief. If response_format=b64_json is selected, only 1 image is supported; use the url return method when multiple images are needed. Batch generation still requires reviewing each result, and you cannot assume all images meet the same detail requirements.
Can I directly copy the mask example for a basic Flare call?
Do not copy it directly. The mask workflow should use the gpt-image-2.5-flare:official endpoint that supports this method, and upload both the original image and the Alpha PNG mask through multipart. For basic Flare reference image editing, first use text to clearly define the modification scope; do not mix the two calling methods.
How do I set an exact canvas size and receive long-task results?
When exact pixels are required, write size as WIDTHxHEIGHT and follow the size limits; use auto when you only want to express composition intent. For long tasks, add callback_url, save the returned task_id first, then receive the completed result; callback handling should deduplicate by task ID to avoid duplicate storage.
