Deploy Azure OpenAI GPT-4o Resource and Model using Bicep

This Microsoft Azure OpenAI article will show how to deploy Azure OpenAI GPT-4o Resource and Model using Bice.

Azure OpenAI is a Microsoft implementation of the popular OpenAI service and AI models. Using Azure OpenAI, companies can use OpenAI’s LLMs with Azure infrastructure, tools, and security and compliance services. It also offers seamless integration with other Azure services.

GPT-4o is OpenAI’s latest AI Model. It offers an integrated AI model with audio, text, and visual capabilities using a single API service.

At CPI, we help companies deploy, develop, and manage AI applications. One of our tasks is deploying AI Services like Vision and GPT-4o. Since we are a Microsoft partner, our preferred infrastructure deployment method is Bicep. Bicep offers many advantages over Terraform, including access to the latest Azure API version.

Install Bicep

Before using Bicep, we need to install the tool. If you are using Azure CLI, the tool is already included with the latest Azure CLI version. If you prefer Azure PowerShell, use the following command (on Windows) to install Bicep.

winget install -e --id Microsoft.Bicep

Connect to Azure

After installing Bicep, connect to Microsoft Azure using the following Azure PowerShell cmdlet.

Connect-AzAccount -UseDeviceAuthentication

Create Resource Group

Since the scope of our deployment is at the Resource Group level, we need to create a resource group using the following cmdlet.

New-AzResourceGroup -Name CPIOpenAI -Location eastus

Create Bicep Template

The following Bicep template (main.bicep) will deploy an AI resource and a model. The model will be the latest GPT-4o model (2024-05-13).

resource openai 'Microsoft.CognitiveServices/accounts@2023-05-01' = {
  name: 'CPIOpenAI'
  location: 'eastus'
 
  sku: {
    name: 'S0'
  }
  kind: 'OpenAI'
  properties: {
   
  }
 
}

resource openaideployment 'Microsoft.CognitiveServices/accounts/deployments@2023-05-01' = {
  name: 'gpt'
  sku: {
    name: 'Standard'
    capacity: 1
  }
  parent: openai
  properties: {
    model: {
      name: 'gpt-4o'
      format: 'OpenAI'
      version: '2024-05-13'
      
    }
    raiPolicyName: 'Microsoft.Default'
    versionUpgradeOption: 'OnceCurrentVersionExpired'
 
  }
}

Save the template.
