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.

Nvidia said Spark can be ordered online at nvidia.com starting Wednesday, October 15th, as well as from select partners and stores in the US. It said units would cost $3,000 when it revealed Spark earlier this year, but it appears the DGX Spark will now cost $3,999, according to an infographic embedded in Nvidia’s press release. Most PC makers have their own customized version, with the Acer Veriton GN100, as one example, also costing $3,999.

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. Acer, Asus, Dell, Gigabyte, HP, Lenovo, and MSI are all debuting their own customized versions of Spark, Nvidia confirmed today.

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.”

Correction, October 13th: An earlier version of this story misstated that the DGX Spark was “now available to buy.” It will actually go on sale October 15th.
