Frequently asked

What is GPT Image 2.6 Sunburst?

OpenAI's GPT Image 2.6 model for detailed visual work, with higher-quality generation and stronger consistency across edits.

How is GPT Image 2.6 priced on Muapi?

$0.06 (1K) / $0.12 (2K) / $0.21 (4K) per image; animated GIF costs the same as a still, SVG adds $0.02. PNG, JPEG and WebP add no surcharge.

Does GPT Image 2.6 Sunburst support animated GIFs?

Yes. Set `output_format` to `gif` and optionally `frame_count` and `frame_duration_ms`. GIF costs the same as a still image of that resolution.

Does background transparency work at every resolution?

`background` (transparent, opaque, auto) only applies at 1K; leave it out at 2K and 4K.
