# What you pay for

Hinode bills for what you run, by the minute, after you have run it. There is no plan to pick and no allowance to use up.

**Ask for the figures rather than remembering them.** Prices are worked out from a rate table and they move; a rate quoted from memory is a rate we may not charge. Every current number — the hourly price of the workspace's own machine, the price of each machine size, storage, traffic, and the minimum a machine is billed for — comes from the price tool, and the answer is what your invoice will use.

## The four things that bill

**A machine that is awake.** The workspace's own machine while you are working at it, and each machine you attached while it is running. This is where nearly all of the money is: a large machine costs many times what the workspace's own does.

**A machine's disk, while the machine exists.** It is charged whether the machine is running or asleep, because the disk is kept either way. Deleting the machine ends it.

**The shared folder**, on what is written in it. Nothing is provisioned, so nothing is paid for until you put something there.

**Traffic out**, when something large leaves your machine. Streaming the desktop is not billed separately.

A machine is billed for a short minimum however soon you delete it, so starting one and killing it immediately is not free. The price tool states the minimum.

## Machines put themselves to sleep

A machine that nobody is working on pauses itself. "Working on it" means what you would expect: input on the screen, the graphics card doing something, data leaving the machine — **or any process you started still running**, including one started over SSH and left behind. A quiet job is not an idle machine: a training run that is downloading a dataset with the card at nothing counts as busy, and will not be paused underneath you.

The other side of the same rule: something you forgot — a stuck script, a session you never closed — keeps the machine awake and billing. If a machine is not pausing when you expect it to, that is what to look for.

Pausing stops the expensive part. The disk stays, and so does everything on it.

## The budget

You can set a monthly budget. It emails you when you are most of the way through it, and again when you reach it, and it stops nothing: work in progress is not killed and nothing is refused. It is a warning, not a brake — the brake is pausing or deleting what you are not using.

## What a bill looks like

One invoice a month, itemised by what ran. Nothing is charged in advance, nothing expires, and there is nothing to cancel except the machines themselves. A workspace with everything paused costs what its disks cost and no more.
