NVIDIA has expanded its Agent Toolkit with new Omniverse libraries, giving AI agents the tools and skills to embed physical AI capabilities directly into developers' existing 3D applications. The move, announced during SIGGRAPH 2026, aims to automate the labor-intensive work of preparing 3D scenes and assets for physics simulation.

AI Agents Learn to Build Simulation-Ready Worlds
NVIDIA's Agent Toolkit gains new open-source Omniverse libraries, letting AI agents automate the manual 3D work of prepping scenes and assets for physics simulation — a push toward a "simulation-first" approach to physical AI.

SK hynix is evaluating Omniverse with the Agent Toolkit for a semiconductor fab digital twin.
Humans stay in control
Agent-ready tools let technical artists retain oversight while assisting with physics testing and simulation prep — tightening the link between design, collaboration and simulation.
Payoff still unproven
Released at the show, so broad independent evaluation isn't yet available. How much time and cost automated prep saves across diverse pipelines will only be clear as third-party adoption grows.
Available now across NVIDIA hardware — from the compact RTX Spark to the DGX Station, cloud or local. RTX Spark units expected autumn 2026 from ASUS, Dell, HP, Lenovo, Microsoft Surface and MSI.
