langchain-ai/deepagents: LangChain Ships Batteries-Included Opinionated Agent Framework — 12.3K Stars, v0.4.11

GitHub·high signal

LangChain has released Deep Agents, an opinionated agent framework built on LangGraph that provides pre-wired planning tools, filesystem operations, shell execution, subagent spawning, and auto-summarization out of the box — inverting LangGraph's low-level graph-primitive approach. Latest release v0.4.11 shipped March 13 2026 with 70 total releases since July 2025, signaling rapid iteration. For builders who found LangGraph too low-level, this is LangChain's direct answer: get a working agent in minutes and customize only what you need.
