Openai Gpt Image 2.6 Sunburst Edit API Documentation

Playground

GPT Image 2.6 Sunburst Edit transforms one or more reference images using natural-language instructions, with a focus on precision, visual fidelity, and consistent detail across iterative edits for polished creative work, brand assets, product imagery, and production workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

OpenAI GPT Image 2.6 Sunburst Edit transforms one or more reference images using natural-language instructions. Sunburst is designed for detailed visual work and image editing.

• Need to generate a new image from scratch instead? Try OpenAI GPT Image 2.6 Sunburst Text-to-Image.
• Need faster turnaround? Try OpenAI GPT Image 2.6 Flare Edit.

Why Choose This?

• Natural-language image editing Edit images by describing the changes you want in plain language; add a mask or a markup layer when the change must land in an exact place.

• Works with reference images Use up to 16 input images as the visual source for edits, transformations, or style adjustments.

• Quality and complexity controls quality sets the rendering detail you pay for; complexity sets how much the model plans the layout before drawing, at no extra cost.

• Up to 4K output and flexible aspect ratios Square, portrait, landscape, and panoramic outputs at 1k, 2k, or 4k.

• Production-ready API Access the model through a ready-to-use REST inference API for fast integration into applications and workflows.

Parameters

How to Use

1. Upload reference images — add images you want to edit.
2. Write your prompt — clearly describe the changes, style adjustments, or composition edits you want.
3. Pick quality and resolution (optional) — medium / 1k is the default; raise quality for more detail or resolution for larger output.
4. Lower complexity for simple requests (optional) — high is the default; try low or medium for short, simple prompts.
5. Choose aspect ratio (optional) — auto-detected from the first input image if not specified.
6. Submit — run the model and download your edited image.

Pricing

Pricing varies by quality and resolution, plus $0.015 for each input image and $0.015 for a mask_image or markup_image. Prices below include one input image.

complexity and the choice of PNG, JPEG, or WebP do not add separate charges.

Notes

• Both images and prompt are required fields.
• mask_image and markup_image apply to the first input image; use one or the other.
• A markup image should contain only annotations on a transparent PNG background and match the first input image’s dimensions.
• The output aspect ratio follows the first image unless aspect_ratio is set.
• Resolution is a size tier; actual width and height depend on the aspect ratio.

Related Models
