Kling 3.0 — three variants, one API surface

Kling 3.0

Kuaishou's flagship video model

Kling 3.0 is Kuaishou's newest video generation model — the reference for cinematic motion realism, physics accuracy, and prompt adherence across long clips.

Text-to-Video

Generate from text prompts

Use kling-v3-t2v to create short clips from text. Strong camera work, subject consistency, and natural motion at 720p-1080p.

Image-to-Video

Animate a still image

kling-v3-i2v turns a single image into a short clip with optional motion prompt. Perfect for product reveals, character animation, and social content.

Motion Control

Camera path control

kling-v3-motion-control adds precise camera path directives (pan, zoom, dolly, orbit) on top of the base model — for storyboard-driven video workflows.

One REST API

No Kuaishou account

Call Kling 3.0 via the ModelsLab REST API. One key, one bill — no Kuaishou signup, no regional restrictions.

Pricing

Transparent per-clip rates

Kling 3.0 on ModelsLab is priced around $0.35-$0.50 per 5-second 720p clip. Free credits on every new account.

Webhooks

Async callbacks

Pass a webhook URL and ModelsLab POSTs the MP4 to your endpoint when generation completes. Essential for long-running video jobs.

SDKs

Python & JavaScript

Official SDKs wrap every Kling endpoint. REST + OpenAPI spec for autogenerated clients.
