After submission, a task_id will be returned. If you provided a callback_url, when the task status becomes finished or failed, a POST request will be sent to the callback_url.
Regardless of whether callback_url is provided, you can retrieve the result through the unified Query Task Status endpoint.

Use gpt-image-2.6-flare to generate one image from a prompt or edit up to 16 reference images. A non-empty image_urls array selects editing automatically; omit it or pass an empty array for text-to-image generation.

Models

gpt-image-2.6-flare — GPT Image 2.6 Flare

Required parameters

prompt is required and supports up to 32,000 characters.

Optional parameters

quality: low, medium, high (default), xhigh, or max.
background: auto (default), transparent, or opaque.
output_format: png (default), jpeg, or webp. Transparent backgrounds require PNG or WebP.
output_compression: integer from 0 to 100. Only allowed when output_format is jpeg or webp; any other format returns a 400 error.
mask_url: optional HTTP(S) mask image URL identifying the area to edit; requires non-empty image_urls.
moderation: auto (default) or low. Controls content moderation strictness; low is less restrictive.
complexity: low, medium, or high (default). Controls the model’s planning effort and does not change the price.
Reference images must use HTTP(S) URLs. Each request produces one output image.

Size

size defaults to 1:1 for text-to-image. When editing without size, the output follows the first reference image’s aspect ratio, using the closest supported ratio at the selected resolution. Supported ratios: 1:1, 2:3, 3:2, 4:3, 3:4, 4:5, 5:4, 16:9, 9:16, 21:9.
resolution supports 1K (default), 2K, and 4K. An omitted size uses a square at the selected tier for text-to-image, or the first reference image’s closest ratio when editing.
Explicit size=auto lets the model determine the image size (about 1.5 megapixels). It works with any resolution and is billed at the 1K tier.
For aspect ratios, actual pixel dimensions may vary by model and generation. Inspect the returned image for exact dimensions; use a custom size when exact pixels are required.
Custom WIDTHxHEIGHT sizes work with any resolution. Both dimensions must be divisible by 16, the longest edge must not exceed 3840, the aspect ratio must not exceed 3:1, and total pixels must be between 655,360 and 8,294,400. The billing tier follows total pixels (up to 1,572,864 is 1K, up to 4,194,304 is 2K, larger is 4K), or the selected resolution if it is higher.
