Robbyant, Ant Group’s embodied-intelligence unit, has released LingBot-World-Infinity (LingBot-World 2.It is a causal video generation model that behaves as an interactive world simulator.It is how the team attacks two failure modes: long-horizon drift and interactive latency.

What is LingBot-World-Infinity?An interactive world model generates video frame by frame, conditioned on a stream of user actions.Each state depends only on past frames and current input.

The research team formalizes this as a causal factorization: Copy CodeCopiedUse a different Browserp_θ(x_1:T | a_1:T) = Π_t p_θ(x_t | x_<t, a_≤t) Here x_t is the visual state at time t.The action a_t combines a camera pose and a text prompt.

Camera pose uses Plücker embeddings, injected through adaptive layer normalization (AdaLN).
