The Case For Multi-Agent: Anthropic's Research System

This chapter draws on two articles that describe the same system: "How Anthropic Built a Multi-Agent Research System" and the ZenML writeup "Building a Multi-Agent Research System for Complex Information Tasks." Together they are the strongest worked example of a multi-agent system that earns its complexity. The system powers Claude's Research feature, which produces in-depth reports grounded in web and enterprise sources.
