Orchestration

Coordinating multiple agents and complex multi-step workflows.

What is Agent Orchestration?

Orchestration is the coordination of multiple AI agents or complex multi-step workflows. It involves routing tasks, managing state, handling failures, and combining agent outputs.

Orchestration Patterns

Common patterns for structuring multi-agent systems.

Sequential Pipeline

Agents run in order, each processing the output of the previous one.

Parallel Execution

Multiple agents work simultaneously on different aspects of a task.

Hierarchical

A supervisor agent delegates to specialized worker agents.

Dynamic Routing

An LLM decides which agent should handle each request.

State Management

Orchestrators must track progress, intermediate results, and handle failures.

Checkpointing

Save state at key points to enable recovery from failures.

Rollback

Ability to undo steps when errors occur.

Supervisor Pattern

A coordinator agent that manages and delegates tasks to specialized worker agents. The supervisor maintains the overall goal, breaks down complex tasks, and synthesizes worker outputs.

Benefits: Clear hierarchy, centralized decision-making, easier debugging

Orchestrator-Worker Pattern

A central orchestrator maintains a pool of worker agents. Workers are stateless and can be dynamically scaled. The orchestrator handles task queuing, load balancing, and result aggregation.

Benefits: Scalability, fault tolerance, resource efficiency

Handoff Mechanisms

How agents transfer control to each other. Popularized by OpenAI Agents SDK, handoffs enable seamless transitions between specialized agents while maintaining conversation context.

Explicit Handoff

Agent directly calls transfer function with target agent and context.

Condition-Based

Automatic transfer when certain conditions are met (e.g., topic detection).

Escalation

Agent transfers to more capable agent when task exceeds its scope.

Group Chat Pattern

Multiple agents collaborate on a shared problem through a structured conversation. Each agent contributes their expertise, with a moderator managing turn-taking and consensus.

Common Roles

  • *Moderator: Controls flow, summarizes progress, resolves conflicts
  • *Experts: Domain-specific agents that contribute specialized knowledge
  • *Critic: Reviews and challenges proposals to improve quality
  • *Executor: Implements the agreed-upon decisions
