𝐅𝐑𝐎𝐌 𝐇𝐀𝐍𝐃-𝐑𝐎𝐋𝐋𝐄𝐃 𝐋𝐄𝐃𝐆𝐄𝐑 𝐓𝐎 𝐋𝐀𝐍𝐆𝐆𝐑𝐀𝐏𝐇 In multi-agent systems, the control plane (orchestration layer) has one critical job: reliably answer “What is this conversation in the middle of, and which agent should handle the next turn?” Almost every serious application today — from enterprise tools to consumer products — is using some form of agentic framework with an orchestrator. LangGraph is one of several modern runtimes that can handle the control plane well. It brings a combination of strong checkpointing, interrupts, and flexible subgraph support: • LangGraph absorbs the heavy runtime plumbing (checkpointing, interrupts, state persistence, routing) • The application keeps full ownership of product-specific details (UI cards, meaningful resumes, cross-store cleanup, domain rules) • LLM is used only for intent perception — routing and lifecycle decisions stay deterministic • The meta-graph works on top of any agent type (LLM+tools, while loops, StateGraphs, custom FSMs, etc.)
