Run one model as cheaply as possible

We're recommending DeepSeek V4 Flash (284B parameters, MIT license) — it needs at least 340.8 GB of GPU memory (params × 1GB, plus 20% working room).

This is a cluster

A cluster just means multiple GPUs or machines working together on one job instead of one machine doing it alone. Real datacenter clustering connects GPUs with NVIDIA's NVLink — extremely fast, direct links that let them share memory and act like one giant GPU. Simply owning several separate cards side by side isn't the same thing: without NVLink between them, they talk over a much slower general-purpose connection and can't pool memory as seamlessly. It works, but it's not true datacenter-grade clustering.

≈ 2.0 average homes running continuously (an average home draws about 1,200 watts around the clock). Over one full day that's 57.6 kWh — about 0.64× a typical electric car battery (roughly 90 kWh).
