Preemptible Instances

Preemptible instances are available for a significantly reduced cost, but they may be stopped at any time by an on-demand customer.

Create a Preemptible Instance

CLI

Use the fluidctl instances create command with the --preemptible flag to create a preemptible instance. For example:

fluidctl instances create --name example --type cpu.8x --preemptible

• --name: The name of the instance.
• --type: The instance type (e.g., cpu.8x, h100-hgx-80gb.8x).
• --preemptible: Indicates that the instance is preemptible.

API

To create a preemptible instance via the REST API, send a POST request to the /instances endpoint with the preemptible field set to true:

POST /instances HTTP/1.1
Host: <your-cluster-url>
Authorization: Bearer <your-auth-token>
Content-Type: application/json

{
  "name": "example",
  "type": "cpu.8x",
  "preemptible": true,
}
