One thing I love about LangChain is how the OSS pieces build on each other You can build robust workflows directly with LangGraph, our orchestration framework. We also use it as the foundation for Deep Agents, our higher-level, highly customizable agent harness As Viv mentions, Deep Agents builds on 𝚌𝚛𝚎𝚊𝚝𝚎_𝚊𝚐𝚎𝚗𝚝. Zoom in one layer and 𝚌𝚛𝚎𝚊𝚝𝚎_𝚊𝚐𝚎𝚗𝚝 is built on LangGraph. Zoom out one layer and Fleet, our managed agent platform, is built on Deep Agents You can use whichever level of abstraction you want create_agent - how we build Deep Agents on the simplest harness primitive underlying all of the harness engineering, research, and API design in Deep Agents is a very simple primitive in LangChain called create_agent the entire design of deepagents comes from optionally extending…
