GPT-Image-2.5 Flare

What is GPT-Image-2.5 Flare?

GPT-Image-2.5 Flare is OpenAI's speed-oriented model for generating and editing images. Its canonical model identifier is gpt-image-2.5-flare. The model accepts written instructions and image references, then returns image outputs rather than general-purpose text responses.

OpenAI positions Flare as the fastest model in the GPT Image 2.5 family and as the default choice for many applications that need a balance between image quality, editing control, latency, and cost. That positioning is a provider claim rather than an independently verified benchmark result.

In practical terms, Flare is intended for workflows such as creating marketing images, producing social and creator content, generating product visuals, transforming reference images, and rapidly testing visual concepts. It is available through OpenAI's Images API and through the image-generation tool in the Responses API.

How Flare fits into OpenAI's image model lineup

Flare belongs to the GPT Image 2.5 family. Within that family, it emphasizes speed and efficient high-volume production. OpenAI positions GPT-Image-2.5 Sunburst as the higher-precision alternative when a user can accept longer generation times for more controlled premium creative work.

This makes the main choice relatively straightforward:

• Choose Flare when response time, iteration speed, and volume are important.
• Consider Sunburst when maximum creative precision is more important than latency.

The supplied documentation does not provide a standardized benchmark showing the exact speed or quality difference between the two models. The comparison above reflects OpenAI's stated positioning, not an independent test.

Inputs, outputs, and supported modalities

GPT-Image-2.5 Flare supports both text and image input. Text prompts can describe a new image or explain the changes required during an edit. Image inputs can act as references, allowing an application to preserve or transform an existing subject, composition, product, or visual identity.

The model produces image output. It does not produce audio, video, or general-purpose text output as its primary result. OpenAI's model information also lists text output as not billed because the model is designed to output images.

• Text input: Supported for generation and editing instructions.
• Image input: Supported for reference-based generation and editing.
• Image output: Supported.
• Audio input or output: Not supported.
• Video input or output: Not supported.

Supported quality settings are listed as low, medium, high, xhigh, max, and auto. These settings provide a way to trade processing requirements and visual fidelity against response speed, although the supplied research does not specify exact resolution, latency, or token consumption for each setting.

What can GPT-Image-2.5 Flare do?

Flare supports both text-to-image generation and image-to-image editing. A text-to-image request might describe a product scene, a presentation graphic, an advertising concept, or an illustration. An editing request can supply an existing image and ask the model to change selected elements while retaining important parts of the original.

OpenAI's documentation highlights improved preservation of subjects and composition during edits. This is useful when an application needs to keep a recognizable product, person, layout, or visual identity while changing the background, styling, arrangement, or other specified details.

The model is also documented as supporting complex layouts, transparent backgrounds, and detailed visual instructions. These capabilities can help with product assets, web graphics, marketing compositions, and design iteration. They should not be interpreted as a guarantee that every prompt will produce an exact layout or flawless text rendering; the supplied research does not provide a separate accuracy benchmark for those tasks.

API access and model identifiers

Developers can select gpt-image-2.5-flare directly through the OpenAI Images API. The model is also available through the Responses API image-generation tool. OpenAI lists the dated snapshot gpt-image-2.5-flare-2026-09-08 in addition to the undated canonical identifier.

Using the dated snapshot can be relevant when an application needs to refer to a specific documented model version, while the undated identifier represents the standard model name supplied in the current model documentation. The supplied material does not specify a separate retirement date or a guaranteed behavior difference between the identifiers.

Flare is an image model rather than a general-purpose assistant model. The model documentation lists streaming, function calling, structured outputs, and fine-tuning as unsupported. Applications should therefore treat the API request as an image-generation or image-editing operation rather than expecting a text response that can directly call tools or return structured JSON.

Context, output, reasoning, and coding limits

The supplied model information does not publish a context-window length or a maximum output-token limit for GPT-Image-2.5 Flare. Those fields should be treated as undocumented rather than assumed to be unlimited.

Flare is not documented as a reasoning model, and no reasoning score or reasoning-specific capability is provided. It is designed to interpret visual instructions and generate images, not to expose a general chain-of-thought or text-based reasoning process.

Likewise, coding is not a supported model capability in the usual sense. Developers can write application code that calls Flare, but the model itself is not presented as a code-generation model. Its documented output is an image, and function calling, structured outputs, and streaming are listed as unsupported.

GPT-Image-2.5 Flare pricing

GPT-Image-2.5 Flare uses token-based pricing rather than one universal price per image. The supplied OpenAI pricing information lists the following rates:

Text output is not billed because Flare produces images rather than text. The final cost of a request depends on the amount of text and image-token processing involved. It can also vary with the selected quality or image settings. Consequently, these rates cannot be converted into one reliable fixed cost for every generated image using the supplied information.

For repeated workflows that reuse the same image or text material, cached-input pricing may reduce the input portion of the bill when the request qualifies for caching. The supplied research does not provide a universal per-image estimate or a detailed token formula for each output size and quality level.

Main strengths

• Speed-oriented positioning: OpenAI describes Flare as the fastest GPT Image 2.5 model, making it suitable for applications where users need quick results or many iterations.
• Generation and editing in one model: It can create images from text and modify supplied reference images.
• Reference preservation: OpenAI highlights improved preservation of subjects and composition during edits.
• Flexible quality controls: Low, medium, high, xhigh, max, and auto settings allow applications to choose a quality and speed trade-off.
• Production-oriented API access: It is available through both the Images API and the Responses API image-generation tool.
• Useful visual formats: Support for complex layouts and transparent backgrounds broadens its usefulness for product, marketing, web, and presentation assets.

The first strength is a provider-stated positioning claim. The remaining points describe documented capabilities, but they do not establish that Flare will outperform every competing image model in every task.

Limitations to consider

• Flare generates images rather than general-purpose textual answers.
• Audio and video input and output are not supported.
• Streaming, function calling, structured outputs, and fine-tuning are listed as unsupported.
• No context-window or maximum-output-token value is published in the supplied model information.
• Pricing is based on token usage, so there is no single guaranteed cost per image.
• The model is not documented as a coding or general reasoning model.

These limitations matter when designing an application. A workflow that needs image creation followed by structured metadata, tool execution, or text reasoning may need to place Flare alongside another model or application component rather than treating it as an all-in-one assistant.

Best use cases

GPT-Image-2.5 Flare is a strong fit for applications that need frequent image generation or editing with relatively low latency. Suitable examples include:

• Social-media and creator content that needs rapid iteration.
• Advertising concepts and marketing assets.
• Product imagery and variations for digital storefronts.
• Visual search experiences that transform or illustrate visual results.
• Presentation graphics, website assets, and transparent-background elements.
• Rapid prototyping during early design and product development.
• Reference-led edits that preserve a subject or composition while changing selected details.

For example, an ecommerce application could provide a product image and ask Flare to place the product in several campaign environments. A design tool could use the model to create quick visual alternatives before a final asset is prepared with a slower, more precision-oriented process.

When should you choose GPT-Image-2.5 Flare?

Choose Flare when the application values fast turnaround, repeated generation, and a practical balance between image quality and processing cost. It is particularly appropriate when users will generate several alternatives, when an application must respond interactively, or when image creation is performed at high volume.

Choose another type of option when the primary requirement is not image generation. A general-purpose language model is more appropriate for text reasoning, coding, structured responses, or function-calling workflows. A video model is needed for video generation, and an audio model is needed for speech or sound tasks.

Within OpenAI's GPT Image 2.5 family, Sunburst may be more appropriate for premium creative work where the best available precision matters more than speed. That recommendation follows OpenAI's stated positioning; the supplied sources do not provide independent comparative measurements.

Overall assessment

GPT-Image-2.5 Flare is a focused OpenAI image model for text-guided generation and reference-based editing. Its defining trade-off is speed-oriented production rather than broad assistant functionality. It supports text and image inputs, image outputs, multiple quality levels, and API access through both Images and Responses workflows.

Its token-based pricing and lack of documented text, coding, tool-calling, and structured-output features mean that it should be evaluated as an image component within a larger application. For fast, repeated visual production and iterative editing, Flare is the GPT Image 2.5 option OpenAI positions as the practical default. For slower, higher-precision creative work or non-image tasks, another model type may be a better fit.
