Xiaomi's new world model can generate a seven-camera driving sequence lasting ~ 45s. It's called Xiaomi Auto World Model 2.0, a unified streaming causal world model for Physical AI. Generating long driving videos comes with a problem: scenes can start to drift over time. Xiaomi tackles this with WorldRec 2.0. It first reconstructs static and dynamic 3D Gaussians from footage captured by multiple cameras across different time steps. Then uses this 3D scene to guide future video generation, helping keep road geometry and visual details consistent over time. The results go beyond video generation. E2E-WM-RL vs. ST-JEPA-E2E in 1,000 closed-loop simulation scenarios: • Collision rate: 1.2% → 0.4%. • Scenario completion rate: 95.2% → 96.3%.
