User management is a core component of Cast AI's role-based access control (RBAC) system. Users represent individual members of your organization who need access to Cast AI resources, whether they're platform engineers managing clusters, developers working with workloads, or analysts tracking costs.

Understanding users in Cast AI

Each user in your organization can be assigned specific roles and access levels, allowing them to perform their required tasks while maintaining security boundaries. Users can be:

Added directly to your organization through email invitations
Automatically provisioned through SSO integration
Assigned to user groups for easier management
Given individual role bindings to specific resources (Coming soon!)

Access levels and scope

When managing users, you can control their access in two ways:

Direct role assignments - Roles can be assigned directly to individual users
Group membership - Users inherit roles and permissions from the groups they belong to

These assignments can be scoped to:

The entire organization
Specific clusters

To learn more about user groups, see User Groups.

User states and authentication

Users in your organization can exist in different states:

Invite pending - Users who have received an invitation but haven't yet accessed Cast AI. Note that a pending invitation can be revoked as well.
Active - Users who have accepted their invitation and can access resources that their role allows.

Authentication can happen through:

Email/password authentication
Single Sign-On (SSO), if configured for your organization

User management

Consider these guidelines when managing users:

Follow the principle of least privilege when assigning roles
Use user groups instead of individual assignments when managing multiple users with similar access needs
Regularly review user access and remove unused accounts
Configure SSO to automate user provisioning and de-provisioning

Default behavior

When users first join Cast AI:

Users invited directly receive the Viewer role by default
Users accessing through SSO receive roles based on your SSO configuration
All new users must accept Cast AI's terms of service and privacy policy before accessing the platform
