Openai Gpt Image 2.6 Sunburst Edit API Documentation
Playground
Try it on WaveSpeedAI!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.
Features
OpenAI GPT Image 2.6 Sunburst Edit transforms one or more reference images using natural-language instructions. Sunburst is the precision-focused GPT Image 2.6 tier: it takes longer per image for higher fidelity and steadier details across repeated edits.

- 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
qualitysets the rendering detail you pay for;complexitysets 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, or4k. -
Production-ready API Access the model through a ready-to-use REST inference API for fast integration into applications and workflows.
Parameters
| Parameter | Required | Description |
|---|---|---|
| images | Yes | Reference images to edit (up to 16). |
| prompt | Yes | Text description of the desired edit. |
| mask_image | No | Mask for the first image: white marks the area to edit, black the area to keep (a PNG where transparent marks the area to edit also works). Resized to the first image automatically. |
| markup_image | No | Transparent PNG of circles, arrows, or notes drawn over the first image to show where and how to edit it. Use either mask_image or markup_image. |
| aspect_ratio | No | Aspect ratio: 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, 2:1, 1:2, 3:1, 1:3, 9:21. Auto-detected from the first input image if not specified. |
| resolution | No | Output resolution: 1k (default), 2k, or 4k. |
| quality | No | Quality tier: low, medium (default), high, xhigh, or max. Higher tiers add detail and cost more. |
| complexity | No | Planning before drawing: low, medium, or high (default). Higher values help detailed, multi-element prompts and take a little longer; the price is the same. |
| output_format | No | png (default), jpeg, or webp. |
How to Use
- Upload reference images — add up to 16 images you want to edit.
- Write your prompt — clearly describe the changes, style adjustments, or composition edits you want.
- Pick quality and resolution (optional) —
medium/1kis the default; raisequalityfor more detail orresolutionfor larger output. - Lower complexity for simple requests (optional) —
highis the default;lowormediumreturns a little faster on short, simple prompts. - Choose aspect ratio (optional) — auto-detected from the first input image if not specified.
- Submit — run the model and download your edited image.
Example Prompt
Turn this product photo into a premium studio advertisement with soft cinematic lighting, a clean beige background, subtle shadows and realistic reflections
Pricing
Pricing varies by quality and resolution. Prices below include one input image. Each additional input image adds $0.015, and a mask_image or markup_image adds $0.015.
| Quality | 1k | 2k | 4k |
|---|---|---|---|
| low | $0.06 | $0.09 | $0.15 |
| medium | $0.09 | $0.145 | $0.24 |
| high | $0.105 | $0.165 | $0.285 |
| xhigh | $0.175 | $0.285 | $0.495 |
| max | $0.375 | $0.615 | $1.015 |
Notes
- Both
imagesandpromptare required fields. mask_imageandmarkup_imageapply to the first input image; use one or the other.- Up to 16 reference images per request; the output aspect ratio follows the first image unless
aspect_ratiois set. - Requests containing sexual content are rejected before generation and are not charged.

Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| prompt | string | Yes | - | The positive prompt for the generation. | |
| images | array<string> | Yes | - | 0 ~ 16 items | List of URLs of input images for editing. |
| mask_image | string | No | - | Optional mask for the first input image: white marks the area to edit, black the area to keep (a PNG where transparent marks the area to edit is also accepted). It is resized to the first image. | |
| markup_image | string | No | - | - | Optional transparent PNG of annotations (circles, arrows, notes) drawn over the first input image to show where and how to edit it. Use either mask_image or markup_image. |
| aspect_ratio | string | No | - | 1:1, 1:2, 2:1, 1:3, 3:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, 21:9 | The aspect ratio of the generated image. If not specified, it is determined automatically from the input image. |
| resolution | string | No | 1k | 1k, 2k, 4k | The resolution of the output image. |
| quality | string | No | medium | low, medium, high, xhigh, max | Rendering quality. Higher tiers add detail and cost more: low is the fastest draft tier, medium is the balanced default, high, xhigh and max add fidelity. |
| complexity | string | No | high | low, medium, high | How much planning the model does before drawing. Higher complexity improves layout and scene understanding on detailed prompts and takes a little longer; it does not change the price. |
| output_format | string | No | png | png, jpeg, webp | The format of the output image. |
Every model also accepts the global request options enable_sync_mode and enable_base64_output; see their pages for details.
