Kuaishou said Kling 4.0 officially launched on October 15, 2026, following an early-access phase in September. The model generates up to 30 seconds of video in a single pass.
What happened
The 30-second single pass is the headline feature. Longer shots can be made in one generation instead of being built from several shorter clips.
Omni Reference, Kling's reference system, accepts up to 15 reference assets and up to 10 keyframe inputs, giving creators more ways to steer characters, objects and timing.
A faster tier, Kling 4.0 Flash, opened on September 28 to a limited group of top-tier annual subscribers.
Kuaishou says Kling 4.0 is integrated with Kling MCP and CLI for agent workflows, so it can be driven by AI agents and scripts as well as through the app.
API and pricing
The status of the developer API was reported inconsistently in October.
Runway's changelog shows Kling 4.0 was added to Runway's developer API on October 23.
Why it matters for creators
Kling 4.0's 30-second single takes and multi-reference control expand what creators can make without stitching clips. Joining shorter clips often introduces jumps in lighting, faces or motion, and a single longer pass avoids those seams. With up to 15 references and 10 keyframes, creators also have more control over how a longer shot unfolds.
The MCP and CLI support matters for teams building automated pipelines, where an agent plans and generates shots in sequence.
KreatorFlow offers the Kling 4 model family.
