LangChain v1 AI Engineer Tree: A Practical Map For Building Agents
Published:
LangChain v1 gives AI engineers a cleaner way to think about agent development. Instead of treating models, tools, prompts, memory, RAG, structured output, middleware, and observability as separate pieces, LangChain v1 puts the agent at the center. The main entry point is create_agent, and almost everything else connects to it: the model, tools, system prompt, middleware, response format, checkpointer, runtime context, state, invocation style, RAG layer, multi-agent patterns, and debugging stack.
