Integrating GPT models into Copilot Studio (formerly Power Virtual Agents) involves several steps, including setting up an Azure OpenAI service, configuring Copilot Studio, and integrating the GPT model to enhance chatbot capabilities. Below is a detailed step-by-step guide explaining how to achieve this.

Step 1: Setting Up Azure OpenAI Service

To integrate GPT models into Copilot Studio, you must first access Azure OpenAI Service, which provides the API for GPT-based models.

1.1 Create an Azure Account

If you don’t already have an Azure account, follow these steps:

1. Go to Microsoft Azure.
2. Click Sign in or Start free (if you don’t have an account).
3. Complete the sign-up process by providing necessary details.

1.2 Access Azure OpenAI Service

1. Navigate to Azure Portal.
2. In the search bar, type Azure OpenAI and click on Azure OpenAI Service.
3. Click + Create to create a new instance.
4. Select the following details:
   • Subscription: Choose your Azure subscription.
   • Resource Group: Create a new resource group or select an existing one.
   • Region: Choose a supported region (e.g., East US, West Europe).
   • Name: Provide a unique name for your service.
5. Click Review + Create, then click Create.

1.3 Deploy a GPT Model

1. Once the Azure OpenAI service is created, open it.
2. Navigate to Models in the left panel.
3. Click Deploy Model.
4. Choose a model (e.g., gpt-4, gpt-3.5-turbo).
5. Provide a deployment name.
6. Click Deploy and wait for the model to be deployed.

1.4 Obtain API Key & Endpoint

1. Go to the Keys and Endpoint section in Azure OpenAI.
2. Copy the API Key and Endpoint URL—these are required for integration.

Step 2: Configuring Copilot Studio

Microsoft Copilot Studio (formerly Power Virtual Agents) is used to create chatbots. Here’s how to set it up:

2.1 Sign in to Copilot Studio

1. Visit Microsoft Copilot Studio.
2. Sign in using your Microsoft account.
3. Click Create a new bot.
4. Provide:
   • Bot Name (e.g., “AI Support Bot”).
   • Language (e.g., English).
   • Click Create.

2.2 Enable Power Automate (Optional)

To integrate external services like GPT, Power Automate helps in connecting the API.

1. Navigate to Power Automate at https://make.powerautomate.com/
2. Click Create → Cloud Flow.
3. Select Instant Flow.
4. Add a new step and search for HTTP (to make API calls).

Step 3: Integrating GPT with Copilot Studio

Now that you have both Azure OpenAI and Copilot Studio set up, the next step is to integrate the GPT model.

3.1 Create a Custom API Call

1. Open Copilot Studio.
2. Navigate to Topics and create a new topic.
3. Click Add Node → Call an API.
4. Configure the API request:
   • Method: POST
   • URL: Paste the Azure OpenAI endpoint (e.g., https://your-openai-instance.openai.azure.com/v1/completions).
   • Headers: Content-Type: application/json Authorization: Bearer YOUR_API_KEY
   • Body: { "model": "gpt-4", "messages": [{"role": "user", "content": "{User Input}"}], "max_tokens": 150 }
5. Click Save & Test.

3.2 Parse the GPT Response

1. Add a Text Response Node to display the AI-generated response.
2. Set the response to be dynamic by inserting the API response.

Step 4: Testing and Deployment

4.1 Test in Copilot Studio

1. Open your chatbot in Copilot Studio.
2. Click Test Bot.
3. Input test queries to verify the integration.

4.2 Publish the Bot

1. Navigate to Publish in Copilot Studio.
2. Click Publish → Confirm.
3. Your chatbot is now live!

4.3 Deploy to Channels

You can integrate your chatbot with:

• Microsoft Teams
• Web Chat
• WhatsApp (via Twilio)
• Facebook Messenger

Go to Channels → Select a platform → Follow the setup instructions.
