Quickstart
Deploy your first Nebula Block GPU instance: pick hardware and a region, attach an SSH key, and connect.
Deploy your first GPU instance.
Before you start
Create an account, or sign in with Google.
Deposit $10 to reach Tier 3, which is what unlocks GPU instances. CPU instances need Tier 2 ($5). See Tiers and Rate Limits.
Add an SSH key so you can log into the instance once it is running.
Create a GPU Instance
Open Deploy in the console.
Choose a Location
Canada, the United States, Finland, France, or Norway. Pick the region closest to you, or the one your data-residency requirements call for.
Select Hardware Configuration
Choose from the available GPU options:
NVIDIA B300 / B200: Blackwell-class training and inference.
NVIDIA H200: Large-model training and high-throughput inference.
NVIDIA H100: Large-scale training, also offered as container and bare metal.
NVIDIA A100: AI/ML training and data analytics.
NVIDIA L40 / L40S: Cost-effective inference and graphics workloads.
NVIDIA RTX series: Budget-friendly rendering and smaller jobs.
Configurations run from a single GPU up to 8-GPU nodes, and 10 in some regions. What is in stock varies by region — the Deploy page shows current availability.
Choose an Operating System/Image
Select an SSH Public Key (if applicable)
Create or select an existing SSH public key for secure access to the instance.
Note that some instances may not support SSH Public Keys yet, in which case a secure username and password will be provided to you.
Set a Server Name
Assign a meaningful name to your instance for easy identification.
Deploy
Review your configuration and click "Deploy". Your instance will be provisioned and ready within minutes.
Connect to Your GPU Instance
SSH Key Authentication
Once your instance is running, connect to it using SSH:
Replace
/path/to/your/private/keywith the path to your private SSH key.Replace
usernamewith the username of your instance, and replaceinstance-ipwith the public IP Address of your instance. You can find the username and Public IP Address information in your instance detail page.
Password Authentication
Once your instance is running, connect to it using SSH:
You'll then be prompted for your password. Simply enter it and press Enter.
Replace
usernamewith the username of your instance, and replaceinstance-ipwith the public IP Address of your instance.You can find the username, password and Public IP Address in your instance detail page.
Manage Your Instance
Open Instances in the console to see everything you have running, and click through for an instance's details, credentials, and firewall rules.
Use the controls there to power on, power off, reboot, or terminate an instance. Some configurations support only terminate.
The same actions are available through the API — see Instances.
Important: An instance is billed for as long as it exists, whether or not it is powered on. Terminate anything you are finished with, and keep an eye on your balance — instances are deleted automatically if you run out of credit.
