This is not an independent test: try both models on the same task before choosing. - [Prices and availability — Mixer AI catalog](https://mixerai.org/knowledge/catalog.json) ## What we compare [ Kling 4.0 Flash A lighter Kling 4.0: clips of 3–20 seconds in 720p from text and references, or from a start frame. ](https://mixerai.org/en/knowledge/video/kling-4-0-flash/) [ Kling 3.0 Turbo One moving shot lasting 3–15 seconds, without configuring a multi-scene sequence or character set. ](https://mixerai.org/en/knowledge/video/kling-3-0-turbo/) ## FAQ Which is cheaper: Kling 4.0 Flash or Kling 3.0 Turbo?
