NVIDIA has begun shipping the world's smallest desktop AI supercomputer, the DGX Spark. Orders were accepted on the company's website, but the computer is now out of stock. The DGX Spark starts at $3,999.
DGX Spark is built on NVIDIA's Grace Blackwell architecture. It uses a 20-core GB10 superchip and delivers one petaflop of AI performance in a power-efficient, compact form factor.
The GB10 comes with a Blackwell GPU, which has the same number of cores as the NVIDIA GeForce RTX 5070. The computer also has 128 GB of LPDDR5x RAM, 4 TB of NVMe storage, four USB-C ports, Wi-Fi 7, and HDMI.
To run artificial intelligence models, NVIDIA DGX Spark supports NVIDIA NIM microservices, FLUX.1 models, NVIDIA Cosmos Reason, Qwen3, etc. In addition, the computer uses NVIDIA's special DGX operating system, which is actually a custom version of Ubuntu Linux, but with additional settings for efficient AI operation.
"In 2016, we built DGX-1 to give AI researchers their own supercomputer. I hand-delivered the first system to Elon at a small startup called OpenAI — and from it came ChatGPT, kickstarting the AI revolution," said Jensen Huang, founder and CEO of NVIDIA. "DGX-1 launched the era of AI supercomputers and unlocked the scaling laws that drive modern AI. With DGX Spark, we return to that mission — placing an AI computer in the hands of every developer to ignite the next wave of breakthroughs."
Interestingly, this time Huang also delivered the first DGX Spark system to Elon Musk at SpaceX’s headquarters in Texas. NVIDIA also previously helped the billionaire’s artificial intelligence startup xAI raise more funding than originally planned.
