# Image Eraser

AI-powered image erasing service. Supports object removal from images via mask and text prompts. Offers high-quality image processing: out-of-the-box REST inference API, top performance, no cold start, affordable pricing.

<Tip>
  This is an **asynchronous** API; only the **task\_id** will be returned. You should use the **task\_id** to request the [**Task Result API**](/api-reference/model-apis-task-result) to retrieve the video generation results.
