Kling 4.0 makes 30-second clips with stereo sound, up to 4K. Watch what early-access creators made with Flash, and start your shots on Kling 3.0 today.
Every model below runs here today on the same credits, so your storyboard can start now.
Made with the full model and with Flash during early access, and posted on X by the people who made them. One prompt each, no stitching.
The new model takes keyframes, references and dialogue in one pass. Gather them now and your first run is a paste, not a rewrite.
Up to ten keyframes per run. Make one still per beat of the scene.
Up to fifteen per run: faces, outfits, locations, a sample clip, a voice.
Lip sync covers multiple languages and accents. Put every spoken line in quotes.
Test framing and pacing here today on one credit balance, then re-run the keepers the day 4.0 opens.
Kling announced Kling 4.0 on September 28, 2026. Flash, the fast tier, is live on Kling's own app for Ultra Yearly subscribers, and the full model follows in October. Kavel does not run it yet and never relabels another model's output as the new one: the generator on this page runs Kling 3.0 until Kling opens 4.0 to API partners.

Kling calls it stable dynamic motion. "Fast movement has seen a huge improvement compared to Kling 3.0!" one tester wrote under this robot boxing match: gloves, sparks and a knockout, all from Flash.
Stereo audio, more accurate lip sync and support for multiple languages, accents and dialects are in the launch announcement. This father and daughter standoff in a dim living room was made on the full model, the creator's focus on emotion and small movements.
"No distortion, no morphing, proper physics understanding, good prompt adherence," wrote the creator of this monk and masked fighter duel in a temple courtyard, a single twenty-second Flash take.

Not yet. Kavel adds it once Kling opens it to API partners. Until then the generator on this page runs Kling 3.0 and labels it Kling 3.0.
