NVIDIA unveils DSX Air to simulate AI factory deployments

NVIDIA announced NVIDIA DSX Air at GTC 2026, a SaaS simulation platform to build full-stack digital twins of AI factories and accelerate deployments.

• Main announcement:NVIDIA DSX Air is a software-as-a-service platform that provides high-fidelity digital simulations of NVIDIA hardware (GPUs, SuperNICs, DPUs, switches) and integrates with partner solutions via open, API-based connectivity, enabling customers to validate compute, networking, storage, orchestration and security and reduce time to first token from weeks/months to days/hours.
• Background & implementation details: Partners and customers (examples: CoreWeave, Siam.AI, Hydra Host) are already using DSX Air; GTC demos included a multi-tenant RTX PRO Server simulation with Netris (network orchestration), Rafay (host orchestration), NVIDIA Run:ai (GPU allocation), a VAST AI Operating System video RAG pipeline demo, and security validations with Check Point, TrendAI Vision One, and Keysight running on simulated BlueField DPUs.
