Build a LangGraph Multi-Agent Researcher

FreeVerified credential3 weeksAdvanced

Overview

What this challenge is about.

Build a multi-agent researcher with eval harness, then compare cost vs single-agent baseline to earn your verifiable certificate.

The scenario

The Amsterdam consultancy (around 40 analysts, paid research for European policy clients) is testing whether a multi-agent prototype can do 70% of an analyst's first-draft work at 20% of the time.

The Brief

What you'll do, and what you'll demonstrate.

Build a four-agent research assistant and quantify when the multi-agent topology beats a single-agent baseline on accuracy, citations, and cost.

Earning criteria — what you'll demonstrate

  • Implement a multi-agent topology with role-specific prompts and tools
  • Define structured message contracts between agents
  • Evaluate multi-agent systems honestly against single-agent baselines
  • Make a cost-benefit call on multi-agent architectures

This challenge maps to Multi-Agent Systems at the Master level. It sharpens the same practical skills your coursework expects — but in a real industry context with actual constraints and deliverables.

Careers

Career paths this challenge builds toward

Completing this challenge demonstrates skills that transfer directly to these roles:

AI Engineer

Building multi-agent topologies with LangGraph and shipping them with eval harnesses is the AI-engineer skill set that AI-agent and consulting orgs hire for in 2026.

  • multi-agent-orchestration
  • langgraph
  • llm-tool-use

Applied AI Scientist

Designing fair multi-vs-single-agent evaluations and writing the cost-benefit memo is the applied-AI work that product orgs need before scaling agents.

This challenge sharpens

  • evaluation
  • multi-agent-orchestration
  • prompt-engineering

Prompt Engineer

Crafting role-specific prompts and structured contracts that survive multi-step coordination is core prompt-engineering work at agent-platform companies.
