fal makes Kling 4.0 video model available, API access coming soon

fal says Kling 4.0, a native multimodal video model, is now live on its platform, available only through the fal UX and fal Agent for now. fal says API access is coming soon but gives no date. fal describes the model as offering improved stability for complex motion, stronger reference consistency across characters and scenes, and more precise control over cinematic storytelling.

Kling AI repeated the announcement on X, confirming the model's availability on fal with the same access limits and the same API timing. Neither post includes pricing or performance benchmarks.
