Function calling

What it means

The model outputs a function name and arguments that the system runs. In agents workflows, function calling often shapes automation and task completion.

How it works

Agents typically run a loop of planning, tool use, and evaluation. Each step updates state so the system can decide what to do next.

Why it matters

Agents help automate multi-step work by combining reasoning, tools, and memory.

Common use cases

• Automating multi-step tasks that span tools or apps.
• Coordinating search, retrieval, and execution to reach a goal.
• Running background workflows with human-in-the-loop checkpoints.

Example

call: get_weather(city=San Francisco).

Pitfalls and tips

Agents can drift if goals are vague or tool permissions are too broad. Clear success criteria and guardrails keep them reliable.
