51WORLD (ASX: 06651) shares experienced a significant rally, climbing more than 10% at their peak during the trading session.

At the time of writing, the stock was up 6.49%, trading at HK$90.25 with a turnover of HK$1.06 billion.

The upward movement follows the company's announcement that its subsidiary, 51Sim, has completed a deep integration and product-level fusion with NVIDIA Cosmos 3 and Alpamayo.

This integration incorporates capabilities for physical world reconstruction and generation, alongside VLA closed-loop simulation and intelligent reasoning verification, into the SimOne4.0 platform.

The development is said to complete the technical chain from real-world data reconstruction to world model generalization and VLA closed-loop reasoning verification.

NVIDIA Cosmos 3 is described as the first full-modal world model for physical AI, while Alpamayo is noted as the first VLA reasoning model designed for autonomous driving.

SimOne4.0 serves as a foundational platform for building world models and VLA native systems for physical AI, integrating five core stages: data, training, inference, verification, and delivery.

Since its initial launch in 2017, the SimOne product series has been adopted by over a hundred global entities, including intelligent vehicle manufacturers, Tier 1 suppliers, technology firms, testing institutions, universities, and research institutes.

Its applications span critical areas from R&D and training to verification and mass production, positioning simulation technology as essential infrastructure in the era of physical AI.
