--- title: "Remix an existing image with Ideogram 4.0, guided by a prompt" method: POST path: "/v2/images/remix/ideogram-v4" tags: ["images-remix"] --- # Remix an existing image with Ideogram 4.0, guided by a prompt `POST /v2/images/remix/ideogram-v4` Transform an existing image with Ideogram 4.0, guided by a text prompt. Supply the source either as an `image_asset_identifier` reference (an image already stored with Ideogram) or as raw `image` bytes (multipart requests only). Supplying both is rejected rather than one being ignored. `image_weight` controls how closely the result follows the source; when omitted the server picks a value from your prompt. Omit `resolution` to keep the source image's shape. The prompt is always interpreted by an instruction-editing model, so there is no `magic_prompt` option. Remixes are not reproducible, so no seed is accepted; the response reports the seed the request resolved to. 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 - RemixImageIdeogramV4Request - `prompt` string, required — The prompt that guides the remix. - `image_asset_identifier` AssetIdentifier — An identifier for an ideogram asset. - `asset_type` 'ASSET' | 'CANVAS_ASSET' | 'LAYERED_ASSET' | 'RESPONSE' | 'UPLOAD', required - `asset_id` string, required - `image` string, binary — The image to transform (max size 50MB), as raw bytes; only JPEG, PNG and WEBP are supported. Multipart requests only. Supply this or `image_asset_identifier`, never both. The bytes are stored as a new image asset in your account, since the remix keeps a durable link to its source image. - `image_weight` integer — Optional. How closely the result should follow the source image, from 1 to 100. When omitted the server chooses a value from your prompt, which is the usual case. - `num_images` integer — The number of images to generate. - `resolution` '2048x2048' | '1440x2880' | '2880x1440' | '1664x2496' | '2496x1664' | '1792x2240' | '2240x1792' | '1440x2560' | '2560x1440' | '1600x2560' | '2560x1600' | '1728x2304' | '2304x1728' | '1296x3168' | '3168x1296' | '1152x2944' | '2944x1152' | '1248x3328' | '3328x1248' | '1280x3072' | '3072x1280' | '1024x3072' | '3072x1024' | '1024x1024' | '896x1120' | '1120x896' | '864x1152' | '1152x864' | '832x1248' | '1248x832' | '800x1280' | '1280x800' | '720x1280' | '1280x720' | '720x1440' | '1440x720' | '512x1536' | '1536x512' — The 1K and 2K resolutions supported for Ideogram 4.0 image generation. - `rendering_speed` 'TURBO' | 'DEFAULT' | 'QUALITY' — The rendering speed to use. - `enable_copyright_detection` boolean, nullable — Optional. Opt this request into post-generation copyright detection. Adds detection latency; flagged images come back with `is_image_safe: false`. - `async` boolean — 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_url` string, 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. - `private` boolean, 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_id` string — A collection you can write to, by its URL-safe base64 collection id. The output images are added to it when the request completes. ## Response `200` The remixed images (synchronous requests), or an acknowledgement to poll with `GET /v1/generations/{generation_id}` (`async` requests). - RemixImageIdeogramV4Response — Response returned by `POST /v2/images/remix/ideogram-v4`. Synchronous requests (the default) include the remixed images 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. - `generation_id` string, required — URL-safe base64 ID of the accepted generation. Accepted by the `GET /v1/generations/{generation_id}` polling endpoint. - `data` RemixedImageObject[] — The remixed images, in generation order. Present only for synchronous requests (`async` omitted or false). - `url` string, uri, nullable — The direct link to the remixed image. Empty when the image did not pass safety checks. - `prompt` string, required — The final prompt the image was generated from. - `resolution` string, required — The resolution of the remixed 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. ## Other responses - `400` — Invalid input provided. - `401` — Unauthorized. - `402` — Insufficient credits or quota. - `404` — The 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. ## Changes - **2026-08-27** `3eb3216eed39` — 2 info - added the new optional request property `webhook_url` (media type: multipart/form-data) - added the new optional request property `webhook_url` (media type: application/json) - **2026-08-26** `204996bf317a` — 1 info - endpoint added [Change history](https://skmtc.dev/ideogram/apis/ideogram-openapi-3-0/changes/v2/images/remix/ideogram-v4/post.md) --- [API](https://skmtc.dev/ideogram/apis/ideogram-openapi-3-0.md) · [All operations](https://skmtc.dev/ideogram/apis/ideogram-openapi-3-0/llms.txt) · [OpenAPI document](https://skmtc-service-production.skmtc.workers.dev/v1/apis/ideogram/ideogram-openapi-3-0/revisions/3eb3216eed39/schema)
