# Account Setup

NVIDIA DSX Air uses [NVIDIA NGC](https://docs.nvidia.com/ngc/latest/ngc-user-guide.html) for authentication and organization management.

## Prerequisites

To use Air, you need an NGC account and organization.

If you do not have an NGC account, go to [ngc.nvidia.com](https://ngc.nvidia.com/signin) and follow the prompts to create an NVIDIA Cloud Account (NCA) and organization. For detailed instructions, refer to the [NGC User Guide](https://docs.nvidia.com/ngc/latest/ngc-user-guide.html#ngc-org-owner-users).

* **Individual orgs** are single-user only.
* **Enterprise orgs** support multiple users, teams, and role-based access. This plan is available to paying customers. Contact your NVIDIA sales representative for more information.

To add additional users to your organization, you need an enterprise org. For more information, see [Adding NGC Users to an Org](https://docs.nvidia.com/ngc/latest/ngc-user-guide.html#adding-ngc-users-to-an-org).

## Log In to Air

1. Go to [dsx-air.nvidia.com](https://dsx-air.nvidia.com) and click **Login**.

You must use a business email address. Personal email addresses (such as gmail.com) are not accepted. If your business email is not accepted and you think this is in error, contact [air-support@nvidia.com](mailto:air-support@nvidia.com).

3. Select the NGC organization you want to use with Air and click **Continue**.

![NGC organization selection](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/dsx-air.docs.buildwithfern.com/4f9cc33c9b7c67134241552cfe624937d3a4ad348f3f4981e8b08049729f60c2/_dot_dot_/docs/assets/images/ngc-org-select.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260915%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260915T165622Z&X-Amz-Expires=604800&X-Amz-Signature=736e4074e71648ffb3b2bed6880506bc0ec5178bb583ce5f0b8cf1b165cca4c1&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)

Air subscriptions and free trials are tied to your NGC organization, not individual users. If you belong to multiple organizations, select the one you want to use for Air simulations.

## Start a Free Trial

If your organization does not have an Air subscription, you may be eligible for a free trial. The trial includes:

| Resource                | Individual Org |
| ----------------------- | -------------- |
| Concurrent vCPUs        | 60             |
| Concurrent memory       | 60 GiB         |
| Compute hours (credits) | 10,000         |
| Duration                | 1 year         |

Only NGC organization owners can start a free trial. If you are the org owner, Air prompts you to start the trial after you log in:

![Free trial offer for org owners](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/dsx-air.docs.buildwithfern.com/902b6559ac85d9eb345c9446a6094adcf03b953b33a070deb31ed98d7c5309af/_dot_dot_/docs/assets/images/free-trial-offer.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260915%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260915T165622Z&X-Amz-Expires=604800&X-Amz-Signature=9ab11dcbcefb26734eced0bb4488ac8614668945d2064f3e9016616f2239a4c7&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)

Click **Start Trial** to activate the free trial for your organization. If you are not the organization owner, contact your NGC organization admin to start the trial.

## Billing

NVIDIA DSX Air bills usage by compute hour, measured down to the minute.

A compute hour represents either:

* 1 vCPU used for 1 hour, or
* 8 GB of memory used for 1 hour

vCPUs and memory are billed independently. For example, a VM with 1 vCPU and 8 GB of memory running for 1 hour consumes 2 compute hours (1 for the vCPU + 1 for the memory).

## Add a User and Assign Roles

To access NVIDIA DSX Air, each user in your organization must have at least one of the following roles assigned at the organization level:

* **Air Org Admin**
* **Air User**

To add a new user to your organization, go to [org.ngc.nvidia.com/users](https://org.ngc.nvidia.com/users) and click **Add a user**.

Always add users through the NGC org management page linked above. Do not invite users through the NVIDIA Cloud Account (NCA) page. Users invited through NCA may not appear correctly in NGC, which prevents you from assigning roles.

To assign roles to an existing user:

1. Go to [org.ngc.nvidia.com/users](https://org.ngc.nvidia.com/users).
2. Find the user and edit their membership.
3. Under **Step 2: Assign Permissions to New User**, select **Organization** as the context for role assignment.
4. Under **NVIDIA Air**, select **Air Org Admin**, **Air User**, or both, then click **Add Role**.

![Assign Air roles to a user](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/dsx-air.docs.buildwithfern.com/aca63ea9a6fe6beded9ac265d550b8cd8b9a86806dea4953a50da88e7298bb09/_dot_dot_/docs/assets/images/assign-air-roles.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260915%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260915T165622Z&X-Amz-Expires=604800&X-Amz-Signature=c042ba7da0dc6e8a2a7868caaad72924e015b417f0035c670b970d2e58389a46&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)

Do not assign the **Air Trainee** role to users. This role is reserved for NVIDIA-led Air training sessions. Assigning the Air Trainee role locks the user's identity in the organization to read-only access and prevents them from creating simulations.

## Troubleshooting

### Cannot Start Free Trial

Only NGC organization owners can start a free trial. If you see a prompt to contact your admin:

![Contact admin to start free trial](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/dsx-air.docs.buildwithfern.com/c8c9351858cd2aab95daaf592b8ef3f584410d1e5b84116558936d7c3b263b65/_dot_dot_/docs/assets/images/free-trial-contact-admin.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260915%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260915T165622Z&X-Amz-Expires=604800&X-Amz-Signature=7a8396f4738907f1f3fc218c2647caf856e8014d2bccb1672ae0726ce0dd433f&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)

Click **Contact Organization Admin** to send a request to your NGC organization owner.

### Missing Roles

If your organization has an Air subscription but you cannot access the platform:

![Subscription exists but user lacks roles](https://fdr-prod-docs-files-public.s3.us-east-1.amazonaws.com/dsx-air.docs.buildwithfern.com/0bc272c47c6ed26f0d09e6d1777e2a2f8e35b52b8bdc25f6acd14784452aef23/_dot_dot_/docs/assets/images/subscription-no-roles.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=AKIA6KXJSKKNFOCF7G4B%2F20260915%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20260915T165622Z&X-Amz-Expires=604800&X-Amz-Signature=0b26908328e8986cc033e09c8a2496f8d8a41016758a58ec71a5ada12f1256cf&X-Amz-SignedHeaders=host&x-amz-checksum-mode=ENABLED&x-id=GetObject)

Contact your NGC organization owner and direct them to [Add a User and Assign Roles](#add-a-user-and-assign-roles) to request the appropriate roles for Air access.
