NVIDIA announced it has started shipping the DGX Spark, which it dubs the world's smallest AI supercomputer, with general availability starting October 15, 2025. This new class of compact, desktop-sized system is designed to make high-performance AI more accessible to developers, researchers, and students by moving AI development from the cloud or data centers to a local machine. The DGX Spark is built on the NVIDIA Grace Blackwell architecture, featuring the GB10 Superchip, and delivers a petaflop of AI performance with 128GB of unified memory. This enables it to run inference on AI models with up to 200 billion parameters and fine-tune models with up to 70 billion parameters locally. Major partners including Acer, ASUS, Dell Technologies, GIGABYTE, HP, Lenovo, and MSI are also set to release their own systems based on the DGX Spark platform. In response to this and other positive news in the AI sector, NVIDIA's stock (NVDA) saw a rally of nearly 3% on the preceding day.
