GPT Image 2.6 Sunburst
OpenAI’s GPT Image 2.6 family includes Flare for fast iteration and Sunburst for detailed visual work. This model ID selects Sunburst directly; it cannot be changed to Flare. This integration delivers raster images at a fixed per-image price. 100 FreeModel credits = $1. Both versions and all quality choices share the same image price. Reference images add no surcharge. See the live model page for current availability.
string
required
Use gpt-image-2.6-sunburst.
string
required
A non-empty visual brief of at most 32,000 characters. For edits, explain what to change and what to preserve.
string
default:"sunburst"
Only sunburst is valid on this model ID.
string
default:"1K"
Only 1K is accepted. 2K and 4K are not part of this route.
integer
default:"1"
Only 1 is accepted. Submit separate tasks for multiple variants.
string
default:"auto"
auto, 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 5:4, 4:5 or 21:9. Custom pixel dimensions are not accepted.
string
default:"auto"
auto, low, medium, high, xhigh or max. Quality does not change the image price; auto does not guarantee low.
string
default:"png"
png, jpeg or webp.
string
Optional: low, medium or high controls planning independently from quality. It does not change the image price.
string[]
Up to 16 public HTTP(S) image URLs or valid PNG, JPEG and WebP Base64 Data URLs. Each image may be at most 20 MiB decoded, with at most 50 MiB decoded in total. The whole JSON request remains subject to the gateway body cap (default 10 MiB); use public URLs for larger files.
This public route rejects unsupported or ignored controls, including background, moderation, output_compression, mask_url, markup, markup_url, pixel dimensions and vendor fallback switches. GIF and SVG output are not exposed.

Receive results

A normal request waits for a terminal image result and returns data[].url on success. Send Prefer: respond-async for HTTP 202 and a gateway task ID. A waiting request may also return 202 if the task is still running. Use an Idempotency-Key for retries of the same submission.
Poll with the same API key until succeeded or failed. A successful task settles its delivered image against the original price version. Explicit failure or cancellation releases the reservation; uncertain results remain pending reconciliation. Repeated polling does not charge twice. Download temporary output URLs promptly.
