Xiaomi opens U0's 34B world model and 4B checkpoint

Xiaomi opened the U0 embodied-world-model stack with a 34B model, a 4B checkpoint, and FSDP training presets; its U0 repository reports 5.44 seconds to generate a 1024×1024 image on one H20 with FlashAR. Those are release and vendor benchmark figures, not proof of robot generalization, but the package turns simulated scene generation and transfer into something researchers can inspect and run rather than a closed demo. Robotics teams should test its scene-variation value against their own robot data before buying another synthetic-data platform; Tau’s supervised home-robot pilot is a reminder that deployment economics still live outside model demos.
