# Transform images with Ideogram 4.5 image-to-image, by asset id or by uploaded bytes

`POST /v2/images/edit/ideogram-4.5`

Generate a new image conditioned on one or more source images, with an
optional prompt to guide the transformation. Supply the sources either
as `image_asset_identifiers` references (images already stored with
Ideogram) or as raw `images` bytes (multipart requests only) — callers
are never required to upload assets first. If both are supplied, the
references win and the bytes are ignored. The first source is the
primary image being transformed; any further sources are additional
references.

By default the request blocks until the output image is ready and
returns it 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`.

## Request body

- EditImageIdeogram45Request — Supply the source images either as `image_asset_identifiers` references or (multipart requests only) as raw `images` bytes. At least one source is required; if both forms are given, the references are used and the bytes are ignored. The first source is the primary image being transformed; any further sources are additional references.
  - `prompt` string — Optional guidance for the transformation. Image-to-image conditions on the source images, so the model can run from the sources alone.
  - `image_asset_identifiers` AssetIdentifier[] — Existing upload or generated image assets to transform, by reference. Takes priority over `images` if both are supplied.
    - `asset_type` 'ASSET' | 'CANVAS_ASSET' | 'LAYERED_ASSET' | 'RESPONSE' | 'UPLOAD', required
    - `asset_id` string, required
  - `images` string[] — The source images to transform (max 5, max size 25MB per image), as raw bytes; only JPEG, PNG, and WEBP formats are supported. Multipart requests only; ignored if `image_asset_identifiers` is also supplied.
  - `num_images` integer — The number of output images to generate.
  - `resolution` string, required — The output resolution, formatted as "WIDTHxHEIGHT", for example "1024x1024" or "1152x768". Required: a source may be a reference-only resolution that is not a valid output, so the output size is never inferred from the sources. Both dimensions must be multiples of 32 and at least 256px, the total size at most 2048x2048 pixels, and the aspect ratio at most 6:1. Pricing is tiered by total pixels: up to 1024x1024 bills as 1K, above that as 2K.
  - `rendering_speed` 'TURBO' | 'DEFAULT' | 'QUALITY' — The rendering speed to use.
  - `seed` integer — Random seed. Set for reproducible generation.
  - `async` boolean — When false (the default), the request blocks until the output image is ready and returns it 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`.

## Response `200`

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

- EditImageIdeogram45Response — Response returned by `POST /v2/images/edit/ideogram-4.5`. Synchronous requests (the default) include the output image in `data`. Requests with `async` set to true omit `data`; poll for completion and results with `GET /v1/generations/{generation_id}` using the returned `generation_id`. The seed reports the value the request resolved to when the caller left it unset.
  - `generation_id` string, required — URL-safe base64 ID of the accepted generation. Accepted by the `GET /v1/generations/{generation_id}` polling endpoint.
  - `data` EditImageObject[] — The output images, in generation order. Present only for synchronous requests (`async` omitted or false).
    - `url` string, uri, nullable — The direct link to the edited image. Empty when the image did not pass safety checks.
    - `prompt` string, required — The edit instruction the image was generated from.
    - `resolution` string, required — The resolution of the edited image, formatted as "WIDTHxHEIGHT".
    - `is_image_safe` boolean, required — Whether the image passed safety checks. If false, `url` is empty.
    - `seed` integer, required — Random seed. Set for reproducible generation.
  - `seed` integer, required — Random seed. Set for reproducible generation.
  - `width` integer, required — The output width in pixels this request resolved to.
  - `height` integer, required — The output height in pixels this request resolved to.

## Other responses

- `400` — Invalid input provided.
- `401` — Unauthorized.
- `402` — Insufficient credits or quota.
- `404` — A referenced source asset was not found.
- `422` — The prompt did not pass safety checks.
- `429` — Too many requests.
- `500` — Internal server error.
- `503` — The endpoint is temporarily unavailable.
