AI Agents

Function Calling

An LLM's ability to output structured requests to call specific functions or APIs, the mechanism that lets agents take real actions.

Definition

A capability where language models generate structured JSON outputs that map to predefined function signatures, enabling them to interact with external systems. The LLM decides which function to call and with what parameters.

Why it matters

The technical bridge between language understanding and real-world action, what makes agents actually useful.

Where Sophizo applies this

Sophizo deploys Function Calling inside revenue and AI engagements with growth-stage operators and PE-backed portfolios.
