Wick Ultra

Built for a frontier model team.

From $688,000

Four NVIDIA Rubin GPUs of your own hold a 1.6-trillion-parameter open model like DeepSeek V4 Pro. Serve it to your team with no queue, fine-tune it on your own data and train what comes next, in your office, your lab or your house.

  • Delivery, with the outdoor unit fitted the same day
  • First year of service and a one-year limited warranty
  • Wick OS included, optional to install
  • 20% to hold it once you accept your price. How you pay

One line of light, cap to cap.

The vertical arm runs the full height in a single gap between the flutes. The horizontal arm wraps both rounded ends and stops where the plain back panel begins.

Stack a second Ultra and the flutes, the caps and the line continue through the join. Each keeps its own 1,152 GB of GPU memory and its own outdoor unit, and joins the other over 800 Gb/s fiber. A third and fourth stand beside them.

What 1,152 GB holds.

DeepSeek V4 Pro needs 800 GB at 4-bit and fits one Ultra with 352 GB to spare. Your weights, your data and every checkpoint live on its own protected SSD. Of the models listed, two outgrow one Ultra and need a Wick Cluster node. Check your own model

Arithmetic from weight sizes and published training rules of thumb. It sizes memory and storage. It does not measure speed.

4.6× the GPU memory of NVIDIA's DGX Station.

Wick Ultra holds 1,152 GB of HBM4 across four NVIDIA Rubin GPUs, 288 GB on each. A DGX Station GB300 holds 252 GB of HBM3e on one NVIDIA Blackwell Ultra GPU, so a single Rubin GPU in Ultra holds more than the whole Station: 1,152 GB ÷ 252 GB.

Memory sets which models fit in one machine; it does not measure speed. One Wick Cluster node holds 2,304 GB, 9.1× the Station.

Quiet in the room. The heat goes outside.

Eleven kilowatts at work, and more than nine of them leave through the wall. Liquid carries the heat through one sealed line to Ultra's own outdoor unit, part of its delivery. What stays in the room at full load is about 1.65 kW, a design target near a portable heater on high, with a 40 dB(A) target at a meter. Wick reviews your room with you before you accept a price.

How fast is a Rubin GPU? NVIDIA's own figures.

NVIDIA's Vera Rubin NVL72 spec table, observed October 23, 2026, gives these for one Rubin GPU. Ultra has four. NVIDIA's January 5, 2026 release states the same 50 PFLOPS of NVFP4 inference3. They are the chip's specifications. Wick has not measured them on Ultra and publishes no tokens per second for your model until it has.

NVFP4 inference, sparse450 PFLOPS
NVFP4 training, dense435 PFLOPS
HBM4 bandwidth, from 288 GB of HBM4419.2 TB/s

Competitor prices are public listings on the dates shown. GB300 is an NVIDIA generation before Rubin. Multiples are rounded to the nearest tenth. Model fit counts weights against GPU memory and does not measure speed. Wick Ultra's price is Wick's list price.
