Kling Omni Video O1 is Kuaishou’s first unified multimodal video model using MVL (Multimodal Vision Language) technology. Its text-to-video mode can generate cinematic videos based on text prompts while maintaining subject consistency, natural physical simulation, and precise semantic understanding.
This is an asynchronous API; only the task_id will be returned. You should use the task_id to request the Task Result API to retrieve the video generation results.
