Original Pull Request: https://github.com/langchain-ai/langgraph/pull/4784

State: closed
Merged: No

Update:

  • Add a prebuilt RAG agent as the create_rag_agent function.

REASON:

  • CrewAI uses the default RAG component a lot, in many workflows. I like it. It speeds up the experimentations, decreases the cognitive load. It is the same as the ReAct agent.

CONS:

  • Compared with ReAct agent, the RAG agent has a heavyweight component, a vector store, which requires a separate initialization.

Discussion:
@eyurtsev Eugene, I did this PR only as a discussion. If you want to move with it, let me know, and I will proceed with these next steps:

  • add a notebook with examples;
  • ? What else?
