Ant Group’s Robbyant Unveils LingBot-VA 2.0: A Causal Video-Action Model Built Natively for Physical AI

Ant Group's Robbyant has released the LingBot-VA 2. 0 technical report — a Physical AI video-action foundation model built from scratch for embodiment rather than fine-tuned from a video generator.

It predicts future states ahead of execution through Foresight Reasoning, re-grounds on every real observation, and reaches 225 Hz asynchronous control. We break down the causal DiT, the sparse-MoE video stream, the semantic visual-action tokenizer, and where the paper's own numbers don't line up.
