LangChain breaks down four multi-agent architectures and when to graduate from a single agent
bibryam · x · 2026-11-05
LangChain's guide explains when multi-agent architectures are worth the complexity: start with a single agent, but switch when context management (specialized knowledge doesn't fit one prompt) and distributed development (team ownership boundaries) become bottlenecks.
Key evidence: Anthropic's multi-agent research system (Claude Opus 4 lead + Sonnet 4 subagents) beat single-agent Opus 4 by 90.2% on internal research evals, thanks to parallel reasoning across separate context windows.
Four patterns covered (with diagrams):
- Subagents: centralized orchestration under a main agent
- Skills: progressive disclosure of capabilities
- Handoffs: state-driven transitions between agents
- Router: parallel dispatch with a synthesizer merging results
