Dark Horse Muka Robotics Charges WorldArena With Only 32 Zhenwu 810E GPUs: LJM World Model Achieves Global Second Place, Marking a Breakthrough From Video Quality to Physical Logic

Muka Robotics’ four-month-old LJM model ranked second globally on WorldArena after an anonymous submission.

It uses a dual-expert design: one module reasons about physical interaction in latent space, while the other renders realistic video.

The model adds explicit constraints for robot motion, object dynamics, and optical flow, tied together with shared attention.

The result suggests architecture, not just compute, can drive better physical understanding, video generation, and robot planning.
