-### Multi-Tenancy
-
-The AI Management module is **fully multi-tenant aware**:
-
-- **Workspaces are isolated per tenant**: Each tenant has their own set of workspaces.
-- **Independent configurations**: Tenants can configure their own AI providers and API keys.
-- **Secure credential separation**: API keys and configurations are never shared between tenants.
-- **System workspaces**: System workspaces defined in code are available to all tenants.

-When working with multi-tenant applications:
-
-```csharp
-// Create workspace for specific tenant
-using (_currentTenant.Change(tenantId))
-{
-    await _workspaceRepository.InsertAsync(new Workspace(
-        name: "TenantSpecificWorkspace",
-        provider: "OpenAI",
-        modelName: "gpt-4"
-    ));
