On-Demand
New instances you create will be billed at on-demand rates by default. You may terminate on-demand instances at any time. On-demand instances are billed continuously for the lifetime of the instance until they are terminated. You must have a balance high enough to support at least one hour of instance runtime prior to creating a new on-demand instance, across all of your instances, including the new instance you intend to create. There is no minimum charge for on-demand instances - while you are required to be able to cover at least one hour of instance runtime at instance creation you may terminate your instance at any time, including before it becomes ready.When billing starts
An instance becomes ready when it is fully provisioned and SSH-accessible. Billing starts the moment an instance becomes ready — you are only charged for time spent in the ready state. While rare, full or partial provisioning errors may occur. Any instance that fails to become ready within the provisioning timeout period (~3 hours) is automatically terminated. You are never charged for instances that never enter a ready state.Price lock
The cost per hour per GPU displayed during instance creation is locked in for the duration of the instance, with one exception: in rare circumstances, we may reach out about a price increase if you have had on-demand instances running at significantly below-market rates for a long time. Instances may be automatically terminated if your account balance is no longer positive. To prevent termination, configure Auto Top-Up to automatically deposit funds when your balance falls below a set amount.Reserved
When creating an instance, you may choose to reserve it for a fixed period of time at a discounted rate.- Paid up-front. Reserved instances are paid in full at creation. Your balance must cover the entire cost of the reservation period.
- Reservation starts at ready. The reservation duration begins the moment the instance becomes ready. If a reserved instance fails to become ready within the provisioning timeout period, it is automatically terminated and the full amount is immediately credited back to your account. You are never charged for instances that never enter a ready state.
- No early termination. You may not terminate a reserved instance yourself. You can extend it before the term ends. At the end of the term, Reservation Protection, which is on by default at launch unless you turn it off, keeps it running at the on-demand rate; with Reservation Protection off it is automatically terminated — save all data to storage that does not live on the instance first.
Reservation Protection: on by default when you launch a reserved instance, unless you turn it off. Instead of terminating at the end of the term, the instance converts to on-demand and is billed at the current on-demand rate until you terminate it. Turn it off in the instance’s settings if you want the instance terminated at the end of the term. See Reserved Overview.
Private Cloud
Private Cloud is arranged under a custom contract and is not self-serve. Once your contract is active, a Private Cloud tab appears in your dashboard. Under Compute, your cluster page shows the capacity you’ve purchased, SSH access for the login node, the node inventory, and the hardware and software configuration. The tab is read-only: start, stop, reboot, and reimage go through the contacts under Support & escalation on the cluster page. Access, management, and payment terms are unique to each contract and are negotiated directly with a sales representative and a technical representative. Contact your sales representative to learn more about accessing and managing your Private Cloud instances.Storage Volumes
Storage volumes are performant, on-prem network storage volumes that live independently from your instances.- Billed by size. Volumes are always billed at on-demand rates based on the total volume size, regardless of the capacity actually used or the volume of data transferred.
- Terminate anytime. You may terminate storage volumes at any time.
