Models
Currently supported Kling model identifiers and the boundary for future model availability.
Available now
| Model string | Status | Notes |
|---|---|---|
kling-v2-6 | Default | The current production Kling model on our pipeline. Used when model is omitted. |
kling-v3-omni | Available | The Omni workflow exposes model-specific reference, storyboard, resolution and audio options. |
kling-v2-6 supports everything documented in Generate a Video: std/pro modes, 5s/10s durations, three aspect ratios, native audio (pro), negative prompts, and up to two reference images (end-frame control in pro).
Kling 4.0 at launch
Kling 4.0 is not integrated on this platform. We have not published a supported model identifier or a migration contract for it. See the availability tracker and official Kling announcements; do not submit speculative model IDs. Any future integration will require verified provider support and documented settings before access is advertised.
Requests with a model string the API doesn't recognize fail with 400 INVALID_INPUT, so you can deploy the new string the moment we announce availability and not before.
Which mode should you use?
std— cheaper and faster; text-to-video and single-reference work. Good for iteration: find your prompt in std, then re-render the keeper in pro.pro— higher render quality, plus the pro-only features: native audio and two-image end-frame control.
For prompt technique — shot lists, camera language, film-stock grading — see the multi-shot prompt guide.
