Pricing
About $0.007982 per image at quality low, $0.017459 at medium and $0.068822 at high, for size 1024x1024 and a short prompt. Billed on n, default 1. $39.00 per 1M image output tokens, $6.50 per 1M text input tokens, $10.40 per 1M image input tokens. The final charge comes from usage.

Input
| Field | Kind | Default | Description |
|---|---|---|---|
prompt required | text | — | A text description of the desired image(s). The maximum length is 32000 characters. |
n | number (whole) 1 to 10 | 1 | The number of images to generate. Must be between 1 and 10. |
size | JSON | auto | The size of the generated images. For `gpt-image-2`, `gpt-image-2-2026-04-21`, `gpt-image-2.5-sunburst`, `gpt-image-2.5-sunburst-2026-09-08`, `gpt-image-2.5-flare`, and `gpt-image-2.5-flare-2026-09-08`, arbitrary resolutions are supported as `WIDTHxHEIGHT` strings, for example `1536x864`. Width and height must both be divisible by 16 and the requested aspect ratio must be between 1:3 and 3:1. Resolutions above `2560x1440` are experimental, and the maximum supported resolution is `3840x2160`. The requested size must also satisfy the model's current pixel and edge limits. The standard sizes `1024x1024`, `1536x1024`, and `1024x1536` are supported by the GPT image models; `auto` is supported for models that allow automatic sizing. |
quality | one of low, medium, high, xhigh, max, auto | auto | The quality of the image that will be generated. - `auto` (default value) will automatically select the best quality for the given model. - `high`, `medium` and `low` are supported for the GPT image models. - `gpt-image-2.5-sunburst` and `gpt-image-2.5-flare`, including their `2026-09-08` snapshots, also support `xhigh` and `max`. |
background | one of transparent, opaque, auto | auto | Set the background of the generated image(s). This parameter is only supported for the GPT image models. Must be one of `transparent`, `opaque`, or `auto` (default value). When `auto` is used, the model will automatically determine the best background for the image. `gpt-image-2.5-sunburst` and `gpt-image-2.5-flare`, including their `2026-09-08` snapshots, support `opaque` and `transparent` backgrounds. Transparent backgrounds are available for supported GPT Image models. For `gpt-image-2` and `gpt-image-2-2026-04-21`, this support is in preview. When using `transparent`, set the output format to `png` or `webp`. |
moderation | one of low, auto | auto | Control the content-moderation level for images generated by the GPT image models. Must be either `low` for less restrictive filtering or `auto` (default value). |
output_format | one of png, jpeg, webp | png | The format in which the generated images are returned. This parameter is only supported for the GPT image models. Must be one of `png`, `jpeg`, or `webp`. |
output_compression | number (whole) | 100 | The compression level (0-100%) for the generated images. This parameter is only supported for the GPT image models with the `webp` or `jpeg` output formats, and defaults to 100. |
