Z-Image Turbo is a high-speed image generation model that supports rapid generation of high-quality images based on text prompts.

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