images-generate

Generate images with Ideogram 4.5 from a text or structured prompt

Generate one or more images with Ideogram 4.5. The prompt accepts either natural language or a structured Ideogram 4.0 JSON prompt; the server detects which was supplied.

magic_prompt controls automatic prompt rewriting: AUTO (the default) and ON rewrite a natural-language prompt, a prompt that is already a valid structured JSON prompt is always consumed directly, and OFF disables rewriting entirely so the model receives your prompt verbatim.

Ideogram 4.5 renders a fixed set of output sizes. When resolution is omitted, the server picks a supported size automatically based on the prompt.

By default the request blocks until the images are ready and returns them in data. Set async to true to return immediately after the request is accepted, then poll for completion and results with GET /v1/generations/{generation_id} using the returned generation_id.

Supplying a webhook_url makes the request asynchronous whatever async says: the response returns as soon as the request is accepted, and the finished result is POSTed to that URL.

Request body

promptstring required

The prompt to generate images from. Accepts either natural language or a structured Ideogram 4.0 JSON prompt; the server detects which was supplied.

magic_prompt'AUTO' | 'ON' | 'OFF'

Determine if MagicPrompt should be used in generating the request or not.

resolutionstring nullable

Exact output resolution, formatted as "WIDTHxHEIGHT". Ideogram 4.5 renders a fixed set of sizes across 1K and 2K tiers (for example 1024x1024, 2048x2048 or 1440x2880); an unsupported size is rejected with a 400. When omitted, the server picks a supported size automatically based on the prompt.

rendering_speed'TURBO' | 'DEFAULT' | 'QUALITY'

The rendering speed to use.

seedinteger

Random seed. Set for reproducible generation.

num_imagesinteger

The number of images to generate.

enable_copyright_detectionboolean nullable

Optional. Opt this request into post-generation copyright detection. Adds detection latency; flagged images come back with is_image_safe: false.

asyncboolean

When false (the default), the request blocks until the images are ready and returns them in data. When true, the request returns as soon as it is accepted; poll for completion and results with GET /v1/generations/{generation_id} using the returned generation_id.

webhook_urlstring uri

HTTPS URL that Ideogram delivers the generated result to. Ideogram sends a JSON POST to this URL once all images for the request have finished generating. The body mirrors the synchronous generate response: request_id, created, and a data array containing every generated image (url, prompt, resolution, seed, is_image_safe). Each delivery is signed with Ed25519 and verifiable against the public keys at https://api.ideogram.ai/v1/.well-known/jwks.json. Must be HTTPS; private and loopback hosts and the cloud metadata service are rejected.

privateboolean nullable

When true or omitted, the output is kept private to your account. Set to false to publish the output to the public feed. Enterprise accounts always generate privately.

target_collection_idstring

A collection you can write to, by its URL-safe base64 collection id. The output images are added to it when the request completes.

Example request

{
  "magic_prompt": "",
  "async": false,
  "private": true,
  "rendering_speed": "DEFAULT",
  "seed": 12345,
  "webhook_url": "https://api.example.com/webhooks/ideogram",
  "enable_copyright_detection": true,
  "target_collection_id": "target_collection_id",
  "prompt": "prompt",
  "resolution": "2048x2048",
  "num_images": 1
}

Response

The generated images (synchronous requests), or an acknowledgement to poll with GET /v1/generations/{generation_id} (async requests).

generation_idstring required

URL-safe base64 ID of the accepted generation. Accepted by the GET /v1/generations/{generation_id} polling endpoint.

seedinteger required
