Build a Multi-Agent Research Team

5 specialist agents, 3 running in parallel, one cited report

1 phase. 6 lessons. 6 labs. Build a multi-agent research system with LangGraph: a Planner that decomposes your question, 3 specialists (Web, Technical, Market) that research in parallel, and a Synthesizer that resolves conflicts and produces a cited Markdown report in 2-4 minutes.

Common questions

Do I need Course 01 first?

Recommended, not required. This course assumes you're comfortable with the basic tool-use/agent pattern; Course 01 builds that from scratch if you haven't already.

Why LangGraph instead of just asyncio.gather like Course 03?

Course 03's orchestrator works well for independent generators with no shared state. This course's agents share a genuinely complex state object (8 fields, some needing reducers) and have real dependencies (specialists depend on the Planner's output) — LangGraph's graph model handles that state management and dependency structure explicitly, instead of you hand-rolling it.

How much does this cost to run?

A full run uses 5 LLM calls (1 planner, 3 specialists, 1 synthesizer) plus web searches — a few cents per report at Haiku/Sonnet pricing, far less than Course 06's coding agent since there's no iterative fix-loop retry cost.

What do I end up with?

A real multi-agent system, `research_team.py "<question>"`, producing a structured, cited Markdown report on any research question in 2-4 minutes — with 3 specialists having genuinely researched it in parallel.
