The company behind China’s Alipay just gave away an AI that builds a playable video game world and keeps it running for a full hour. Robbyant, the robotics arm of fintech giant Ant Group, open-sourced its LingBot-World 2.0 world model this week. It generates an interactive 3D world in real time, at 720p and 60 frames per second, that a user can walk around and act inside.
That release was not a one-off. It was the finale of a remarkable week. Across four days, Robbyant open-sourced an entire robot brain, piece by piece: the eyes, the hands, and now the imagination. For a company most people know through a payments app, it is a bold land-grab in embodied AI.
An hour-long world you can play
Start with the headline act. Most AI video tools generate a clip and stop. LingBot-World 2.0 keeps going. The company says it holds visual quality for a full hour with no drift, where rival systems usually blur and collapse after a while.
It is also interactive, not just watchable. On Robbyant’s Reactor platform, a user steers a character with the keyboard as the scene renders live. The action list reads like a game: attack, shoot arrows, cast spells, jump, and glide. Type a command and you can flip the world to night, change the weather, or drop in a new object.
