On March 17, 2026, NVIDIA unveiled that the DGX Spark now supports cluster networking among up to four units, facilitating the construction of a compact “desktop data center.” Each unit, affectionately dubbed the “Little Golden Box,” delivers a remarkable 1 petaFLOPS of AI computing power and comes equipped with 128GB of LPDDR5X unified memory. When four units are operated in parallel, the computing power soars to an impressive 4 petaFLOPS, while the unified memory capacity expands to 512GB.

The DGX Spark supports a variety of operational topologies, utilizing ConnectX-7 network cards to enable low-latency RoCE (RDMA over Converged Ethernet) communication. This setup is optimized for a range of scenarios, including low-latency inference and fine-tuning of large AI models. NVIDIA asserts that the parallel operation of multiple DGX Spark units achieves near-linear performance enhancements without the need for intricate configurations.

Furthermore, the DGX Spark introduces a cutting-edge open-source technology stack that supports the local development and deployment of long-running, autonomous AI agents. This stack seamlessly scales to data center infrastructures, such as AI factories, enhancing flexibility and efficiency. Presently, the DGX Spark has been deployed across a diverse array of industries, including finance, healthcare, energy, and telecommunications, demonstrating its versatility and wide-ranging applicability.
