Domestic Video Models

Domestic video models provide a unified OpenAI-compatible interface, supporting multiple generation modes such as text-to-video, image-to-video, first-and-last-frame video generation, motion control, digital humans, and lip sync.

Quick Start

Video Generation

POST /v1/videos, submit domestic video tasks, supporting multiple generation scenarios.

Task Query

GET /v1/videos/{task_id}, query task status and results.

Integration Methods

Domestic video models use the following interfaces in a unified way:

Operation	Endpoint	Description
Create Task	`POST /v1/videos`	Submit a video generation task
Query Status	`GET /v1/videos/{task_id}`	Query task progress and status
Get Content	`GET /v1/videos/{task_id}/content`	Get the video download URL

Note: Different model series may provide multiple integration methods.

Vidu: Official format (/vidu/ent/v2/*), OpenAI format (/v1/videos), unified video (/v1/video/create)

Jimeng: OpenAI format (/v1/videos), unified video (/v1/video/create), Doubao channel

Kling: OpenAI format (/v1/videos)

This page mainly introduces the general specifications of the OpenAI-compatible interface. For model-specific interfaces, please refer to the model documentation below.

Model Documentation

Detailed documentation for the following mainstream models is currently provided first:

Jimeng Video

Documentation for generating and querying jimeng-video-3.0 and jimeng-video-2.0.

Vidu Video

The three integration methods for the viduq3-pro, viduq2, and viduq1 series.

Kling Video

Multiple generation modes for Kling-3.0-Omni, Kling-2.6, and Kling-2.5.

Detailed documentation for other models (GV-*, OS-*, Hunyuan-*, Mingmou-*, Hailuo-*, SV-*, JV-*) is being organized. You can refer to Domestic Video Model Generation for general parameter specifications and usage methods.
