LangGraph v1.1.3 ships deep-agent templates and distributed runtime in the CLI

Requesty·medium signal

LangChain's LangGraph reached v1.1.3 with prebuilt 'deep agent' templates and distributed runtime support exposed through the CLI, building on earlier state-persistence and human-in-the-loop checkpoint work. The distributed runtime targets the scaling pain of long-horizon multi-agent graphs that outgrow a single process. For teams already on LangGraph, the templates lower the boilerplate for planner/researcher-style deep agents.
