Function Calling
Allowing an AI model to trigger external actions or retrieve live data during a conversation.
Function calling (also called tool use) is a capability that lets LLMs invoke predefined functions during a conversation. Instead of only generating text, the model can call a function to check live inventory, book a calendar slot, look up a CRM record, or send an email — and incorporate the result into its response. Function calling transforms a passive chatbot into an active agent that can take real-world actions on behalf of the visitor.
