Model Overview

Review shared video-model fields, differences, and entry pages for each video model.

Current public video models also use POST /v1/generations. The main differences are reference-image fields, resolution enums, and default duration.

The fields most likely to cause integration mistakes are reference_videos, reference_images, resolution, and duration.

How to Choose a Video Model

Choose seedance-2 for higher resolutions, seedance-2-fast for speed, and seedance-2-mini for lightweight jobs.
Kling quality tiers use mode: std, pro, and 4k where declared by the model schema.
Kling V3 Omni and Kling Video O1 accept reference_videos; include input_video_duration with video input.
Available models and parameters vary by region, API-key access, and route health. Treat GET /v1/models as authoritative.
