Fast GPT Image 2.5 model for image generation and editing.

Model Information

Field	Description
`model`	gpt-image-2.5-flare
`endpoint`	POST /v1/images/generations

Capabilities and Usage

quality supports auto, low, medium, high, xhigh, and max.
Use auto or WIDTHxHEIGHT for size: both edges are multiples of 16, no edge exceeds 3840 px, aspect ratio is within 1:3-3:1, and total pixels are 655360-8294400. Above 3686400 pixels is experimental.
Transparent backgrounds require PNG or WebP. Generation uses JSON; editing uses multipart image/image[] and optional mask. Do not wrap image parameters in metadata.
