function calling

An overview of AI agent tool calling: how models choose and invoke APIs, databases, and services to plan, act, and verify. It details function schemas, grounding, permissions, retries, and monitoring; compares single-call vs multi-step/agent orchestrations; and outlines trade-offs in latency, cost, and reliability. Practical patterns, safeguards, and evaluation tips help teams ship safe, effective, production-grade automations.
