“Closed-loop world model simulation is a foundational capability in Li Auto's intelligent driving R&D. We build and own our simulation platform to match our own technical architecture. In that process, we worked closely with NVIDIA on neural reconstruction, multi-GPU parallel training, asset generation, and visual consistency. Integrating relevant NuRec capabilities into key stages of our pipeline improved scene reconstruction efficiency and multimodal simulation quality, accelerated validation and production deployment of related technologies, and contributed to our ability to continuously evolve our autonomous, scalable closed-loop simulation infrastructure.”
