MoWorld 2.0: Chinese startup folds 10+ physics factors into one 4D world model at 70FPS on Ascend NPUs

Moxin (MoCore), founded by Zhejiang University PhD student Chen Tianrun, released the MoWorld 2.0 general 4D world model at the Wuzhen World Internet Conference. Beyond spatial generation and real-time interaction, it integrates 10+ physical factors—gravity, elasticity, buoyancy, fluids, soft/rigid bodies, heat—into one model, simulating forces, collisions and environmental change. Key techniques include a physics Gaussian renderer and multi-expert prediction over physics, pixel and Gaussian signals; generated scenes export as 3D/4D Gaussian assets editable in game engines, film pipelines and robot simulation (e.g., generating a walkable ancient market from a painting).

After 1 year of Huawei collaboration, task partitioning across multiple Ascend NPUs, sparse-attention optimization and mixed-precision quantization push real-time inference from 50 to 70 FPS, with inference costs as low as 30% of comparable GPU setups. An on-device app, "Mo Xiao Chong," already shipped on new Huawei phones (600M-param edge model on Kirin). The company raised 2B RMB across 5 rounds this year at a near-10B valuation, positioning itself as a "Chinese Cosmos" physical-world foundation model for automakers and embodied AI.
