The ARM API for Microsoft.CognitiveServices/accounts/deployments (2025-06-01) requires a
modelProviderData field when creating deployments for third-party model providers (Anthropic). The azurerm_cognitive_deployment resource has no corresponding argument, causing
all Anthropic model deployments to fail with a 400 on create.

azurerm_cognitive_deployment

Terraform Version

v1.14.1

AzureRM Provider Version

4.54

Affected Resource(s)/Data Source(s)

azurerm_cognitive_deployment

Terraform Configuration Files

resource "azurerm_cognitive_deployment" "claude-sonnet-4-6" {
  name                 = "claude-sonnet-4-6"
  cognitive_account_id = azurerm_cognitive_account.foundry.id
  rai_policy_name      = "Microsoft.DefaultV2"

  model {
    format  = "Anthropic"
    name    = "claude-sonnet-4-6"
    version = "1"
  }

  sku {
    name     = "GlobalStandard"
    capacity = 1
  }
}

Debug Output/Panic Output

InvalidModelProviderData: ModelProviderData is required for Anthropic model deployments but 
was not provided. Please provide all required fields: industry, organizationName, and countryCode.

Expected Behaviour

A model_provider_data block should be available, e.g.:

model_provider_data {
organization_name = ""
industry = "Other"
country_code = "US"
}

Actual Behaviour

The resource cannot be created via Terraform at all. The only workaround is to create
the deployment manually in the Azure AI Foundry portal and then import it into state.

Steps to Reproduce

terraform apply

Important Factoids

No response

References

Workaround

Create the deployment manually in AI Foundry portal, then:
terraform import azurerm_cognitive_deployment. <resource_id>

Additional Context

• ARM API version used by azurerm 4.54.0: 2025-06-01
• modelProviderData is required on PUT but not returned on GET, making import viable
  but initial creation impossible through Terraform
• Affects all third-party model providers, not just Anthropic
