I had a great time last month at the Boston Office User Group (video recording can be found here) where we created a Power Virtual Agent Bot that connects to OpenAI’s ChatGPT and Dall-E services, which allows users to chat as well as create images.
Key components of the bot:
- This bot utilizes OpenAI; it would be fairly easy to replace that with an Azure OpenAI resource by updating the url of the HTTP calls in Power Automate and the authentication method (api-key Header instead of the Authorization / Bearer Header)
- By default, the Fallback topic is setup to take what a user types and submit it to ChatGPT (the chat capability)
- Users can type ‘bogimage‘ to switch to the image generation feature
- At anytime, users can type ‘restart‘ to go back to the chat conversation
- To keep the solution as close to the presentation as possible, only a few small updates have been made:
- Small updates to text for more clarification on how to navigate between chat and image capabilities
- Cleaned up code to determine location of ending comma since it’s not needed because we always at minimum have a system message, and so commas in the history can be added before each additional message
How to Setup Bot:
- Create an OpenAI account and a related API Key
- Create an Azure Key Vault in your related Azure environment or utilize an existing key vault
- Create a key called “openaikey” and enter your personal OpenAI api key from above step
- Ensure the account you’ll be using to import the solution has been added to the key vault with “Key Vault Administrator” role (it’s possible to user a lower level of access if needed but the account you’ll create the connection with below must be able to read the key)
- Download the Solution file
- Go to your preferred Power Platform environment’s “Solutions” section (make.powerapps.com)
- Click “Import Solution” and select the downloaded file from above
- When prompted to select or create an Azure Key Vault connection, select “Default Azure AD application for OAuth” and type in the name of your key vault created in step 2 above. Ensure you complete the sign-in process to authorize the connection
- After the solution has finished importing, go to your environment’s chatbot environment, find the Bogbot, and begin chatting with your new bot!
Cheers,
Matt
