Multi-Agent

▲ Rising

Several specialized agents working together on one task instead of one agent doing everything.

Think of it like

A film crew — director, editor, sound — each expert at one job, coordinating toward the same movie.

Example

A research task uses a planner agent to outline, several worker agents to gather sources in parallel, and a writer agent to stitch the report.

How it actually works

Splitting a job across agents lets each hold a focused role and prompt, and lets some run in parallel. The cost is coordination: agents talk past each other, duplicate work, or compound each other’s mistakes. Often a single well-prompted agent beats an elaborate committee — multi-agent earns its keep mainly when the subtasks are genuinely independent.

For product teams

Tempting for hard problems, but more agents means more ways to fail — reach for it only when the work truly splits.

For engineers

Multiple agent instances with distinct roles and contexts, coordinated via a shared orchestrator or message passing.
