OpenAI Assistants with Function Calling

The ai CLI allows you to extend OpenAI's models with custom functions (e.g. dates, times, math, filesystem).

Prerequisites

Before you begin, you'll need to install the ai CLI and set up Azure OpenAI.

Install the ai CLI
Setup Azure OpenAI

Create an Assistant

Create an assistant
ai chat assistant create --name MyFunctionAssistant

Use the Assistant with Built-in Function Calling

Ask the assistant the current time
ai chat --user "What time is it?" --built-in-functions
Calculate a power
ai chat --user "What is 3.5 to the power of 9?" --built-in-functions
Read a file
ai chat --user "What is in the README.md file?" --built-in-functions
Save content to a file
ai chat --user "Save the pledge of allegiance to 'pledge.txt'" --built-in-functions

Delete the Assistant

Delete the assistant
ai chat assistant delete
ai config --clear assistant.id

The ai dev new command allows you to generate sample code that demonstrates how to use OpenAI Assistants with Function Calling.
