I went down this path a bit the other night, curious what OP's answer is. My mental model was that they could be complimentary? Jido for agent lifecycle, supervision, state management, etc, LangChain for the LLM interactions, prompt chains, RAG, etc. Looks like you could do everything in Jido 2.0, but if you like/are familiar with LangChain it seems like they could work well together.

See my other comment, but Jido 1.0 used (Elixir) Langchain

As LLM API's evolved, I needed more and built ReqLLM which is now embedded deeply into Jido.
