Deep Agents: Building Long-Running Autonomous Agents with LangChain's New Framework

Deep Agents: Building Long-Running Autonomous Agents with LangChain's New Framework The era of single-turn, reactive agents is ending. As engineering teams push toward workflows that span hours instead of seconds—internal coding pipelines, multi-stage research synthesis, iterative design systems—the limitations of flat tool-calling architectures become painfully obvious. You cannot orchestrate a code review that spawns test generation, runs CI, waits for human approval, and then deploys without
