Dynamic Subagents: How to Run Parallel Agents Reliably in Deep Agents
Multi-agent architectures have quietly become the default for anything more ambitious than a single-turn chat, but when to reach for them — and how to keep them from blowing up your token budget — is still guesswork in most codebases. In this 26-minute LangChain talk, Colin Flaherty lays out a clean, prescriptive mental model built on top of Deep Agents: sub-agents are just a way to parallelize work and control what returns to the parent context, and there are exactly four patterns worth memorizing....
