GPT Image 2.5 Flare 2026-09-08
GPT Image 2.5 Flare is intended for everyday image generation from descriptions. Provides custom sizes, an extended set of quality levels and transparent backgrounds.
About the model
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
Everyday generation from text descriptions
GPT Image 2.5 Flare is an OpenAI model for creating images. According to the manufacturer, its purpose is fast everyday generation of high-quality visual material. A prompt can describe the subject, style, detail placement and desired frame shape; the result is an image.
In Ailoot, this card presents generation with text input. OpenAI also describes work with source images, references and edits. These methods require image-input support; they do not mean that the text method already accepts such material.
Quality from a draft to a detailed image
The levels low, medium, high, xhigh, max and automatic selection with auto are supported. Quality affects the amount of work performed when forming the result. It is specified separately from frame size and compression of the finished file.
Square, landscape and portrait size options, automatic selection and custom sizes are provided. Aspect ratios can be selected to suit a composition while meeting all manufacturer limits.
Custom sizes
Each dimension must be a multiple of 16 pixels and no longer than 3840 pixels. The ratio of the longer dimension to the shorter must not exceed 3:1. Permitted area is between 655,360 and 8,294,400 pixels. The limits apply together: a permitted aspect ratio does not remove the area limit.
Resolutions above 2560x1440 are designated as experimental. When selecting a large frame, the composition itself matters: more pixels do not guarantee correct placement of every element.
Output file and transparency
The model provides PNG, JPEG and WebP, with PNG as the standard format. Compression can be controlled for JPEG and WebP. A transparent background requires PNG or WebP. The manufacturer also supports an opaque background and automatic selection. Transparency allows an image to be used in a later composition without a specified backdrop.
Manufacturer settings describe model capabilities; execution depends on parameter support in the selected method. A separate generation creates a new result, so an identical description does not guarantee that images match completely.
What to check in the finished image
According to OpenAI, a complex prompt may take up to two minutes to process. This describes generation with the manufacturer, not a guarantee of total result-delivery time in a particular application.
Text, precise object placement and preservation of one appearance across images need checking. A mask in a separately supported editing operation guides the change rather than imposing a hard boundary. For text-to-image generation, it is useful to describe the composition precisely and inspect the file itself: visible details, readability and conformity to the specified subject.
