AI Orchestration: Coordinating Agents, Tools, and Flows

A real AI product is rarely one model call. Who decides which call happens first, which ones run together, and what happens when one of them fails?

In short: AI orchestration is the coordination layer that connects models, tools, data, memory and agents into one reliable workflow. It decides the order of steps, passes data between them, handles branching, retries and errors, and keeps state. Five patterns cover most systems: sequential, parallel, conditional, loop and orchestrator-worker.

Key terms in this lesson

AI orchestration
Coordinating LLM calls, tools, data, memory and agents so they complete a task together.
Orchestrator
The component (code or an LLM) that decides which step runs next and with what inputs.
Workflow
A system whose steps and branches are fixed in code, with LLMs inside the steps.
Routing
Choosing which branch, model or agent should handle an input.
Fan-out / fan-in
Sending work to several parallel steps, then gathering and merging their results.
Evaluator-optimizer loop
Generate, check, revise, repeated until a check passes or a limit is hit.
