Kling AI started early access to Kling 4.0 Flash for a limited group of users on September 28, 2026. Kling says the full Kling 4.0 is coming, with a wider rollout planned for October 2026.
What to know
- The new creation experience is rolling out gradually from September 28.
- Kling says version 4.0 builds on version 3.0 with upgrades to audiovisual performance, multimodal references and storytelling.
- Kling 3.0, launched on February 5, 2026, remains the broadly available generation: clips up to 15 seconds with native audio.
Because access is limited, check Kling’s own page before planning a project around 4.0.
