Inputs

prompttextarearequired

The prompt for image generation

image_sizeselectdefault: "landscape_4_3"

The size of the generated image. Supports preset names, explicit {width, height}, or 'auto' to let the model pick the best size. Concrete sizes must have both dimensions as multiples of 16, max edge 3840px, aspect ratio <= 3:1, total pixels between 655,360 and 8,294,400.

Options: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9, auto

backgroundselectdefault: "auto"

Background for the generated image

Options: auto, transparent, opaque

qualityselectdefault: "high"

Rendering quality for the generated image. For SVG output it controls the reference image used to create the vector.

Options: auto, low, medium, high

reasoning_effortselectdefault: "high"

How much the model plans before rendering, independently of quality (OpenAI `complexity`). Higher levels can help with dense text and complex layouts but add latency.

Options: low, medium, high

num_imagesintegerdefault: 1

Number of images to generate. Must be 1 for SVG output. For GIF output, all frames of all outputs share the request's pixel budget.

output_formatselectdefault: "png"

Output format for the images. 'gif' returns an animation and 'svg' a vector image.

Options: jpeg, png, webp, gif, svg

output_compressioninteger

Compression level from 0 to 100. Only supported when output_format is 'jpeg' or 'webp'.

frame_countintegerdefault: 9

GIF only: number of frames. image_size applies to each frame; reduce size or count if the request exceeds the pixel budget.

frame_duration_msintegerdefault: 200

GIF only: milliseconds per frame, rounded to 10 ms.

svg_modelselectdefault: "gpt-6-astra"

SVG only: the model that converts the generated reference image into vector paths. Larger models produce more accurate shapes.

Options: gpt-6-astra, gpt-5.5, gpt-5.4, gpt-5.6-terra, gpt-6-luna

sync_modebooleandefault: false

If `True`, the media will be returned as a data URI and the output data won't be available in the request history.

enable_safety_checkerbooleandefault: true

Authorized callers may set false to request relaxed screening.
