Kling 4.0 hands-on tests and comparisons

After testing Kling 4.0, a user says the biggest surprise is not more features but better control over results, with adjustable styles and motion and up to 10 keyframes to direct a scene, shown in four personal tests.

Release details for Kling 4.0: stable motion in complex scenes, fluid camera direction, native 30-second generation, and Omni Reference with up to 15 reference inputs and 10 keyframes.

Kling 4.0 is now generally available via the refreshed kling.ai interface plus MCP and CLI, with longer native clips, tighter control, 4K 10-bit HDR and team/developer API access promised next.

A Turkish user fed character and location images via Omni Reference and generated a single 1080p 30-second fight clip for 405 credits, finding it still trails Seedance on physical contact and action but beats the rest.

A user reports Kling 4.0 offers a new quick-generation UI, MCP and CLI access, up to 30-second videos, and flexible reference inputs.

A user breaks down the cost of a 30-second Kling 4.0 Omni video across subscription tiers: $4.77–$3.17 in the first month rising to $6.00–$4.30 on renewal, with Standard not listing 4.0 access.

Kling AI released the Kling 4.0 video generation model, supporting native clips up to 30 seconds, combinations of up to 15 reference materials, up to 10 keyframe inputs, stronger facial detail, and multilingual generation.

A short Japanese post says Kling 4.0 is officially out and lists it with Seedance 2.5, Wan 3.0 and MiniMax H3 as the four top video models, without specs or hands-on tests.

Kling 4.0 is now available to everyone with up to 30-second single generations, stereo audio with tighter lip-sync, and a new canvas with an Agent; the poster says their own tests are coming.

Same-scene comparison: Flash tops out at 720p while Kling 4.0 outputs 1080p with native 4K promised, showing better image quality and character emotion, though Turkish pronunciation remains wrong.

Official feature rundown: audio-visual upgrade, dynamic motion, dual-channel stereo, 4K/1080p 10-bit HDR output (coming soon) and up to 15 omni-references.
