deprecated: false
description: >
Layer decomposition with Seedream 5.0 Pro: split an image into a base
image and separate layers.
:::tip
The base image and every separated layer each count as one billed image;
in auto mode the model decides the number of layers, so the cost varies
per request. For current prices, see
[kie.ai/pricing](https://kie.ai/pricing).
:::
## Query Task Status
After submitting a task, use the unified query endpoint to check
progress and retrieve results:
Learn how to query task status and retrieve generation results
::: tip[]
For production use, we recommend using the `callBackUrl` parameter to
receive automatic notifications when generation completes, rather than
polling the status endpoint.

name: ''
value: seedream/5-pro-layer-decomposition
callBackUrl:
description: >-
The URL to receive task completion notifications. Optional,
but recommended for production environments.
- Upon task completion, the system will send a POST request
to this URL
- The callback content includes task status, generated
result URLs, and task information
- You can also actively query the task status through the
get task details interface
- For callback signature verification methods, please refer
to the [Webhook Verification
Guide](/common-api/webhook-verification)

input:
description: Input parameters for the layer separation task
properties:
prompt:
description: >-
Optional prompt for layer separation.
- When a prompt is provided, the model separates the
specified elements based on the prompt
- When no prompt is provided, the model automatically
identifies the main elements in the image
- Supports using `x1 y1 x2 y2` to precisely
specify element positions, recommending the use of
normalized coordinates in the 0-1000 range
