The Kling v2.6 Pro Text-to-Video tool generates high-quality dynamic videos from text prompts, with support for synchronized audio and video generation.

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.
