# Create GPU Instance

> Learn how to create a GPU Instance and configure the billing mode, network, specifications, Image, storage, and Logon Credential.

After creating a GPU instance, you can run deep learning training, model fine-tuning, inference services, or other GPU-accelerated tasks on the instance. GPU instances use bare-metal resources. When creating one, you must configure the billing mode, region, network, specifications, image, storage, logon credential, and optional components.

## Procedure

1. Log in to the [GPU Cloud console](https://console.scitix.ai/gpu-cloud/home) and go to the **Instance** page.

2. On the **GPU Instance** tab, click **Create GPU Instance**.

3. In the **Billing mode** section, select a billing mode.

   | Parameter | Description |
   | - | - |
   | **Pay-as-you-go** | Billed based on actual usage duration. Suitable for short-term tasks, temporary validation, or tasks with an uncertain runtime. |
   | **Subscription** | Billed by subscription period. Suitable for tasks that run stably over the long term. Subscription durations of 1 month, 3 months, 6 months, 12 months, and 24 months are available. |

4. In the **Basic Information** section, configure the HostName and Region.

   | Parameter | Description |
   | - | - |
   | **HostName** | The instance hostname. You can select **IP Address-based Hostname** and specify a hostname prefix, or select **Custom** and enter a hostname. When creating instances in batches, running multi-node tasks, or distinguishing node order by hostname, after selecting **Custom**, you can optionally select **Custom Hostname Order** to make hostnames easier to identify and manage later. |
   | **Region** | The region where the instance is located. The region cannot be changed after the instance is created. |

5. In the **Instance & Image** section, select the network, specifications, Image, and runtime environment.

   | Parameter | Description |
   | - | - |
   | **Instance** | GPU Instance currently uses a Bare Metal Instance. |
   | **RDMA** | Select the RDMA network to be used by the instance. |
   | **Instance Spec** | Select a specification that meets task requirements. Specification cards display vCPU, Memory, GPU model, Price, and the number of instances that can be created. |
   | **Image** | Select the base OS image to be used by the instance. |
   | **Install GPU Driver** | Choose whether to install the GPU driver. When running GPU tasks, it is recommended that you confirm the driver version based on the image, CUDA, framework, and task requirements. |
   | **Driver Version** | If Install GPU Driver is selected, select the GPU Driver Version. |
   | **Container Network Mode** | Used to configure the network initialization mode for the instance. |

   If your workload has no specific container network requirements, we recommend keeping the default options. If existing workloads depend on legacy provisioning network behavior, select **Use Legacy Provisioning Behavior**.

6. In the **Storage** section, configure the data disk.

   | Parameter | Description |
   | - | - |
   | **Mount Data Disk** | Select whether to mount a data disk. |
   | **FsType** | Select the file system type for the disk. Currently, `ext4` and `xfs` are available. |

7. In the **Authentication** section, configure the **Logon Credential**.

   | Parameter | Description |
   | - | - |
   | **Logon Credential** | Select **Custom Password** or **Key Pair**. |
   | **Logon Username** | Select a logon username. Currently, `root` and `ces-user` are supported. |
   | **Logon Password / Confirm Password** | When **Custom Password** is selected, enter and confirm the logon password. |
   | **Select Key Pairs** | When **Key Pair** is selected, choose an existing key pair. If you plan to use key pair logon but do not currently have an available key pair, [create a key pair](https://docs.scitix.ai/gpu-cloud/instance/manage-key-pairs.md) first. |

8. In the **Options** section, select whether to install optional components.

   | Parameter | Description |
   | - | - |
   | **Install Assistant** | After installation, the platform can assist in maintaining CES instances. |
   | **Install Monitor** | After installation, instance monitoring data can be collected and used for monitoring and alerts. |

9. Check the **Estimated Cost** on the right, and confirm the Instance Type, quantity, and Balance information.

10. Click **Continue** to proceed to the **Review** step.

11. After verifying that the configuration is correct, submit the creation request. Once creation is complete, confirm that the instance status is as expected on the **Instance** page.
