Function calling allows ChatGPT to intelligently invoke external functions and APIs, making it a powerful orchestration layer for complex workflows.
How It Works
- Developer defines available functions and their parameters
- User makes a natural language request
- ChatGPT determines which function to call and with what arguments
- Developer executes the function and returns the result
- ChatGPT incorporates the result into its response
This is the foundation of most production AI agent systems.
