# Hunyuan Image 3

Hunyuan Image 3.0 is a state-of-the-art text-to-image generation model. By simply providing a written prompt, you can create high-quality images that capture the essence of your story, resonate emotionally, and elevate your creative output.

<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 generation results.
