# GLM Image Generation

GLM Image text-to-image generation tool creates high-quality images from text prompts, producing HD images with fine details and high consistency.

<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.
