GPT Image 2.6 Sunburst

OpenAI's precision image model, now with animated GIF and SVG vector output. GPT Image 2.6 Sunburst generates and edits images at 1K, 2K, or 4K with five quality levels up to Max, native transparent backgrounds, up to 16 reference images for exact, instruction-following edits, and up to 4 images per run, with a planning setting for dense text and complex layouts.

$0.03per image (16:9 PNG; square images cost more). GIF and SVG at 1:1.(~30 credits)Best price

67% less than the priciest provider (7 compared). Same model, same output.

As of November 7, 2026, GPT Image 2.6 Sunburst costs from $0.016 per image on Scenetra, billed at provider cost with no markup. Each run is priced across 7 providers and runs on the cheapest one that supports your settings.

Text to Image“A bright, casual phone photo of a busy farmers market fruit stall on a sunny morning: crates of strawberries, peaches, lemons, blueberries, green apples, cherries, plums and figs, each crate with its own handwritten cardboard price sign, a smiling vendor in a denim apron weighing fruit, shoppers with tote bags in the background, natural light, unbranded”

Promptrequired

Input imagesoptional

Optional images to edit or use as reference (up to 16). Leave empty for pure text-to-image.

Resolution

Output resolution tier.

Aspect Ratio

Aspect ratio of the generated image. 'auto' lets the model choose.

Quality

Rendering quality. Low is a fast draft; xhigh and max push detail for final assets. The price difference is large.

Background

Transparent requires PNG, WebP or SVG output. Auto lets the model decide.

Output Format

File type of the result. GIF returns a short looping animation; SVG returns an editable vector file.

Complexity

How much the model plans before rendering. Higher helps dense text and complex layouts; no extra cost.

Frame Count

GIF only: number of frames (2-8, or 16).

Frame Duration Ms

GIF only: how long each frame shows, in milliseconds (20-2000).

Request fields

Field	Type	Description	Default

callbackUrl	string (https URL)	Optional. When the run finishes (completed or failed), we POST the final run status to this URL — same shape as the poll response, plus `model`, `params`, and `chargedCredits`. Best-effort; polling remains the source of truth.

Unknown fields are rejected with a helpful 400. Media fields take https URLs. There is no provider parameter — every run is routed to the cheapest capable provider automatically.

Good to know

Billing

Runs bill your account credits at provider cost with 0% markup. The submit response includes the credit estimate; failed generations are refunded automatically. Add ?dryRun=1 to get the estimate without running anything.

Errors

Errors are always { "error": { "code", "message" } } with stable codes: unauthorized, model_not_available, invalid_parameter, insufficient_credits, rate_limited. A failed run is not an HTTP error — poll responses report status: "FAILED" with the reason.

What makes GPT Image 2.6 Sunburst different

Built for editing precision

Sunburst is the precision tier of GPT Image 2.6: it spends more time per image and follows edit instructions closely while leaving everything you didn't ask to change untouched. Attach up to 16 reference images to revise a shot, combine subjects and styles, or carry a product across scenes, and because edits hold steady, multi-step refinements build on each other instead of drifting.

Animated GIF and SVG vector output

Set Output Format to GIF for a short looping animation (2 to 8 or 16 frames, with a frame duration you control; 8 frames at 200 ms by default) or to SVG for an editable vector file. An 8-frame GIF (1:1, Medium) costs about $0.03, and a Medium SVG about $0.049. Generated GIF and SVG files are final outputs: they can't be wired into other nodes.

Planning setting for dense layouts

The new Planning control (Low, Medium, High, High by default) sets how much the model plans before it renders. Higher planning helps with dense text, infographics and complex multi-element layouts, and it adds no cost.

Five quality tiers, transparency and 4K

Low, Medium, High, Extra High and Max let you match spend to purpose inside one node: Low drafts start at $0.016 per image at 1K (16:9) and Medium is about $0.028. Render straight to a transparent background with PNG, WebP or SVG output, in eleven aspect ratios at 1K, 2K or 4K. Every run goes to the cheapest capable provider for your exact settings, billed at provider cost with 0% markup; the node shows the price before you run.
