Nvidia will start selling its DGX Spark “personal AI supercomputer” this week. The machine is powerful enough to let users work on sophisticated AI models but small enough to fit on a desktop.

From Wednesday, Nvidia said Spark can be ordered online at nvidia.com, as well as from select partners and stores in the US. It has not revealed final pricing but said units would cost $3,000 when it revealed Spark earlier this year.

Spark boasts the kind of performance that once required access to pricey, energy-hungry data centers. It could help democratize AI and would be particularly useful for researchers. When first announcing Spark earlier this year (then called Digits), Nvidia CEO Jensen Huang said “placing an AI supercomputer on the desks of every data scientist, AI researcher and student empowers them to engage and shape the age of AI.”

Buyers can expect to see a variety of similar models on the market as Nvidia has said third-party manufacturers are welcome to make their own versions. Asus, Dell, and HP are among the companies that have said they are working on their own versions of Spark.

Spark comes with Nvidia’s GB10 Grace Blackwell Superchip, 128GB of unified memory, and up to 4TB of NVMe SSD storage. Nvidia says it can deliver a petaflop of AI performance — meaning it can do a million billion calculations each second — and is capable of handling AI models with up to 200 billion parameters. It’s also small, comfortably fitting on a desk and running from a standard power outlet. Nvidia calls it “the world’s smallest AI supercomputer.”
