GPT Image 2.6 Sunburst Reverse
gpt-image-2.6-sunburst:reverse is the public invocation ID for GPT Image 2.6 Sunburst. It is equivalent to gpt-image-2.6-sunburst and retains an explicit alias for callers to choose. It focuses on precise composition and editing, supports text-to-image generation and reference image editing, and uses the GPT Image 2.5 image API.
Bring this model into your workflow
Submit requests to the public API at api.acedata.cloud using the documented parameters, then use the results in your application.

Choose a Model
Flare focuses on fast generation and editing, while Sunburst focuses on precise composition and editing. Explicitly specify gpt-image-2.6-sunburst:reverse; do not use gpt-image-2.6 with the variant name omitted.
Text-to-Image Generation
Submit a prompt through the image generation API describing the subject, scene, lighting, color palette, and aspect ratio. You can first generate one image to check the composition, then adjust the quality and size as needed.
Edit Reference Images
Submit image and prompt through the image editing API. JSON accepts image URLs, while multipart accepts local files; provide up to 16 reference images. Explain the role of each image and what needs to be preserved or modified.
Billing and Results
Billing is based on the number of successfully generated images, with a base price of 0.22 Credits/image. The returned Token statistics do not change the per-image billing method. By default, read the image links in data; when b64_json is selected, only one image is returned. For long-running tasks, you can pass async or callback_url and use the original task_id to query the completed result.
Usage Limits
Use auto or WIDTHxHEIGHT for size. Width and height must be multiples of 16, the longest side must not exceed 3840, total pixels must be 655,360–8,294,400, and the aspect ratio must not exceed 3:1. n is 1–10, and b64_json requires n=1. This API does not currently support SVG/GIF. Version 2.6 does not configure cross-model substitution.
Frequently Asked Questions
Do generation and editing use the same model?
Yes, both endpoints use the full gpt-image-2.6-sunburst:reverse.
Are xhigh and max supported?
Yes, both generation and editing support them; higher quality may increase wait time and official usage.
How should the reverse suffix be understood?
It is an explicit alias corresponding to the standard version and is billed by the number of successfully generated images.
How is official billed?
It is billed based on actual Token usage, with the same rates as 2.5 official, rather than a fixed per-image price.
What should I do if asynchronous waiting times out?
Keep the original task_id and query the task status to avoid submitting duplicate generation requests.
