GPT-Image 2.5 Flare API
GPT-Image 2.5 Flare is one of the two provider ids behind OpenAI's 2.5 image generation on OmniaKey: text-to-image and reference edits, low, medium or high quality, and an exact WIDTHxHEIGHT canvas at flat per-call pricing.

01
Where it fits
Make Flare the default 2.5 route: at the same size and quality it measured identical to Sunburst, so pick it whenever you want the 2.5 generation.
02
What it does
Text to image
gpt-image-2.5-flare
Turn a text prompt into a new image.
Image edit
gpt-image-2.5-flare
Change an existing image from a prompt and reference input.
03
Call it
Media models run asynchronously. Create a task, poll it until it finishes, then download the signed asset URL.
# 1. Create the job. 202 Accepted; the body carries the task id,
# the pre-charged price, and a poll_url. Reuse one Idempotency-Key
# across retries so a timeout never starts a second paid job.

Frequently asked questions
How do I call GPT-Image 2.5 Flare on OmniaKey?
POST to /v1/media/tasks with the model id, type "image", and operation "generate" or "edit". Reuse one Idempotency-Key across retries so a timeout never starts a second paid job.
What does GPT-Image 2.5 Flare cost?
GPT-Image 2.5 Flare bills $0.068 per call. Creation pre-charges that amount from your prepaid balance, and failed or canceled jobs are refunded automatically.
Why does the API return a task id instead of the image?
Provider latency runs from seconds to about a minute, so OmniaKey normalizes every image route into one asynchronous lifecycle. Poll GET /v1/media/tasks/{id} until the status is succeeded, then read the signed asset URL.
