KLING V1.6 Text-to-Video is an AI text-to-video generation model developed by the Kuaishou AI team. It can transform text descriptions into dynamic 5-second 720p videos, delivering high-quality visual output with enhanced motion and semantic understanding capabilities.
This is an asynchronous API and will only return 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.
