What We Know About Kling 4.0 Flash
Released first
Flash went live on September 28, 2026, the day Kling announced the 4.0 generation. The full Kling 4.0 is scheduled for October.
Ultra Yearly only for now
Access is currently limited to Kling's Ultra Yearly subscribers. Kling has not said when, or whether, it will open to other plans.
Built on the Kling 4.0 generation
Flash belongs to the Kling 4.0 generation. The published capabilities — 30-second generations, up to 10 keyframes, up to 15 Omni References — describe the generation as a whole. Kling has not published Flash's own complete parameters, so this page does not guess numbers.
