# Create a private cluster

Create a private cluster with the GPU plan, node count, and billing you choose, ready to allocate
its nodes to your projects. The cluster belongs to the location you create it in, and its nodes,
allocations, and billing stay there.

## Before you begin

You need the **Owner** or **Admin** role on the project. Only these two roles can
create, change, or delete a private cluster; see
[Nodes, projects, and access](/tir/tir-private-cluster/concepts/nodes-projects-and-access/).

## Choose the GPU plan

1. In TIR, open your project. In the side menu, under **PRODUCTS**, select **Private Cluster**, then
   select **Create Private Cluster**.
2. Under **Select Computing Resource**, on the **GPU** tab, choose a GPU card: **H200**, **H100**,
   **A100**, **L40S**, or **L4**, each shown with its memory size. They are the same GPUs TIR
   offers for its GPU nodes.
3. Choose how to pay. The GPU's plans appear once you choose it:
   - **On-Demand** bills every node by the hour for as long as the cluster exists. Choose it for
     short or variable work, or while you learn how many nodes you need.
   - A committed plan, named for its term, such as **1 Month Savings Plan** or **1 Year Savings
     Plan**, is paid upfront for the whole term at a lower rate per node. The longer the term, the
     lower the rate. Choose it for steady, predictable work.

   The terms on offer depend on the plan. For how each is billed, see
   [Billing options for TIR Private Cluster](/tir/tir-private-cluster/concepts/billing-options/).

## Name the cluster and set its size

1. Under **Cluster Configuration**, keep the generated **Cluster Name**, such as `p-cluster-a1b2`,
   or type your own of up to 50 characters.
2. Set **Node Count**. It starts at 1 and goes up to the number of nodes free for the plan you chose.
   Start with the smallest count your work needs: you can add nodes later from **Update
   Configuration**, and the node count can only grow.

## (Optional) Turn on MIG

To split each node's GPUs into smaller, isolated GPU instances, turn **MIG Enable** on. MIG,
short for Multi-Instance GPU, suits notebooks, inference services, and lightweight training jobs that
run well on a slice of a GPU. It applies to every node in the cluster, and you set it only here. For the
instance sizes it offers, see
[GPU partitioning with MIG](/tir/tir-private-cluster/concepts/gpu-partitioning-with-mig/).

## Create the cluster

1. Select **Create Private Cluster**.
2. If you chose a committed plan, a dialog asks what happens when the term ends. Choose one:
   - **Auto Renewal** buys another term at the committed rate when this one ends. Choose it for a
     cluster you will keep.
   - **Convert to Hourly Plan** keeps the cluster and bills it by the hour after the term.
   - **Auto Delete** deletes the cluster when the term ends. Choose it only for a cluster whose
     work ends with the term.

   Your choice takes effect only when the term ends.

3. If your account runs on free credit, a confirmation about your balance opens. Confirm it to continue.

TIR shows "Cluster created successfully.", returns to **Manage Private Cluster**, and opens
**Allocate Nodes to Projects** for the new cluster. Its nodes are **Free**, ready to allocate. If the
create fails, TIR shows "Failed to create cluster" with the reason.

## Check the cluster

In **Manage Private Cluster**, the new cluster shows its **Total Nodes**, with all of them under
**Available Nodes**, and its **Plan**. A cluster with MIG on shows **Mig: Enabled**.

Next, give its nodes to a project in **Allocate Nodes to Projects**, or later from the cluster's
**Actions** menu; see [Allocate nodes to
projects](/tir/tir-private-cluster/how-to/allocate-nodes-to-projects/). For help with a message on
the form, see [Troubleshooting TIR Private
Cluster](/tir/tir-private-cluster/troubleshooting/tir-private-cluster/).
