Our recommendation: run DeepSeek V4 Flash on 3× H200 NVL
DeepSeek V4 Flash is the biggest bang per dollar on the open leaderboard: frontier-class answers with only 13 billion parameters active per token, which keeps it fast on modest hardware. Three H200 NVL cards bridged by NVLink give you 423 GB — comfortably over its 340.8 GB requirement — for less than a fifth of the price of a DGX.
DeepSeek V4 Flash has 284 billion parameters × 1 GB = 284 GB, + 20% working room = 340.8 GB needed — this build carries 423 GB.

The smallest card that takes big models seriously.
1,800 W — as much as about 1.5 average homes drawing power around the clock, and a day of running it uses about 48% of a 90 kWh electric-car battery.
Several cards, one machine — how does that work?
A cluster is several machines (or cards) wired together tightly enough to work on one job as if they were one. These cards are joined by NVLink bridges at 900 GB/s, so the model sees their memory as one pool. That direct wiring is exactly what desktop cards lack — which is why we sell this and not a pile of gaming cards.
