Kling 2.5 Turbo is an advanced text-to-video model capable of generating ultra-smooth motion, cinematic visuals, and content that closely matches the prompt.
This is an asynchronous API that only returns the asynchronous task’s task_id. You should use this task_id to request the Get Task Result API to retrieve the video generation result.
