MotuBrain Tops WorldArena and RoboTwin2.0 Rankings

刚刚，国产AI双冠王！黑马世界模型打破全球纪录，一镜到底封神

Shengshu MotuBrain scored 63.77 EWM on WorldArena and 95.8/96.1 on RoboTwin2.0 Clean/Randomized. The post says it extends Motus with video-action modeling, Latent Action VAE, MoT, and UniDiffuser for cross-embodiment long tasks. Track reproducibility: it does not disclose training scale, submission details, or real-robot success rates.

Why it matters: HKR-H/K/R all pass, but this is a single-source benchmark claim. Training scale, submission details, and real-robot success rates are not disclosed, so it stays below the 78+ band.
