Start by creating a new directory for your Terraform project and initializing it:

mkdir azure-openai-terraform
cd azure-openai-terraform
terraform init

Next, create a file named main.tf and add the following content:

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 2.65"
    }
  }
}

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "openai_rg" {
  name     = "openai-resource-group"
  location = "eastus"
}

resource "azurerm_cognitive_account" "openai" {
  name                = "my-openai-account"
  location            = azurerm_resource_group.openai_rg.location
  resource_group_name = azurerm_resource_group.openai_rg.name
  kind                = "OpenAI"
  sku_name            = "S0"
}

This configuration creates a resource group and an Azure OpenAI cognitive account, laying the foundation for your AI infrastructure.

import json
from azure.keyvault.secrets import SecretClient
from azure.identity import DefaultAzureCredential

# Retrieve API key from Azure Key Vault
key_vault_url = "https://your-key-vault.vault.azure.net/"
secret_name = "openai-api-key"

credential = DefaultAzureCredential()
client = SecretClient(vault_url=key_vault_url, credential=credential)
api_key = client.get_secret(secret_name).value

endpoint = "YOUR_AZURE_OPENAI_ENDPOINT"

headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {api_key}"
}

data = {
    "prompt": "Translate the following English text to French: 'Hello, how are you?'",
    "max_tokens": 60
}

response = requests.post(endpoint, headers=headers, data=json.dumps(data))

print(response.json())
