fal Worlds lets you explore and direct AI-generated worlds in real time

fal Worlds lets you build characters, explore environments, and direct AI-generated scenes that react to your actions in real time.

The explore page includes walkable worlds and short stories you can steer, running models such as LingBot World and H3 Max Director.

Developers can also stream sessions through fal's API. The LingBot World 2 endpoint takes movement and camera commands and streams 1664×960 video at 48 fps over WebRTC. It costs $0.00125 per compute second of video generated. The real-time client is an alpha release and may change.
