AI Micro-Nodes

Three nodes. One open design for every roof.

For a flat, for a detached house and for a business: this is how each SG is built, part by part, from what we have already assembled and measured. Nothing on this page comes from a catalogue: it comes from a node that is up and running. Touch the parts, assemble it step by step and see where the energy comes in and where the compute goes out.

SG1, SG2 and SG3 are reference designs: open, assembled and measured. The SG7 and the SG70 come next.

At a glance

Same design, three sizes.

The same recipe in all three: a consumer motherboard, a GPU with its native connector, a meter between the wall and the power supply, and the network you already have. What changes is the card — and with it the compute, the power and what you earn.

Measured on nodes that are up and running. Compute: catalogue PFLOPS in sparse FP8; the number in the name. Power: measured at the wall. Equipment: the node's cost excluding VAT, the same figure the calculator uses. Rate: the minimum of each band published on 2026-10-23; the details, in Rates.

SG1 For a flat · Flat with solar

A desktop with a good card, wherever a computer fits.

The node for a flat with surplus: a single consumer GPU, an ordinary case and about 400 W when working flat out. It makes the noise of a computer and fits in a cupboard, a storage room or a utility room.

SG2 For a detached house · Detached house with solar

A 96 GB professional card in a desktop case.

For a house with its own roof and surplus to spare: the same size as the SG1 and four times its compute, with an RTX PRO 6000 Blackwell Max-Q that draws 300 W. It is the node we serve 120-billion-parameter models with.

SG3 For a business · Business with solar

SG3 schematic. Amber: the surplus, from the sun to the power supply. Green: the compute, from the node to the customers. Touch a part, in the drawing or in the list, to see it in both.

How it is assembled

Five steps, in the order we assembled it. Click one and the schematic shows it.

  1. 1Motherboard on the bench: CPU, seven-heatpipe cooler, memory and the two NVMe drives.
  2. 2Test bench without the case: power supply connected, first boot on the integrated graphics and a memory check.
  3. 3The case: it is assembled with the top removed; the EPS cables are connected before the bracket goes back.
  4. 4The two GPUs, each on its own power-supply connector; in the BIOS, IOMMU in passthrough mode.
  5. 5System, meter and onboarding: Ubuntu 24.04, NVIDIA "open" driver, containers, the meter between the wall and the power supply, and onboarding to the platform.

What all three share

The same operation, whatever the size.

  1. System and containers

    Ubuntu 24.04, NVIDIA "open" driver, Docker with GPU access. Each customer runs in their own container, with a memory ceiling and no view of the rest of the node.

  2. Measured at the wall

    A smart plug measures what the node consumes. That is the figure you are paid on: "=" when measured, "≈" when modelled, and never a zero where nothing was measured.

  3. Run by agents

    The price is set every 15 minutes, health is monitored and incidents are logged. You see it in the app: what it has earned today and this month, what it has consumed and whether it is healthy.

  4. Security as standard

    No monitor or keyboard, key-only access, a firewall with the bare minimum open and the customer's network kept apart from yours. The node assumes that whatever runs inside it is not to be trusted.

Shall we build yours?

Tell us what roof you have and we will tell you which node fits it.

The calculator uses your surplus to estimate which of the three is yours and how much it pays you per month. If you would rather go through it together, write to us: we build the node, we run it and you earn for every kWh.
