New LangChain XML Agents

[@XavierNV]

Great video as always, have been following you for a while now and always appreciate the knowledge you share for free! You have helped me go from a beginner in LLMs to embedding advanced agents into my applications, cannot thank you enough!

[@jamesbriggs]

Thanks I appreciate the comment, I'm happy it's helped!

Hey, will you be doing tutorials about the new Self-reflective RAG? :)

[@gfxmrsaltman]

Hey James, really appreaciate your videos. I am currently working on a Project that is supposed to be a RAG Chatbot with multiple Website(s)-Data. The "problem" I am facing is that I need the assistant/bot to be able to make a "knowledge" switch, depending on the context of the conversation. Do you have any idea, how I could implement that? The additional data is stored in Chroma Vectorstore(s). I could also think of using the chunk metadata for that purpose but I wanted to know what you would do/recommend in this kind of situation. Cheers

New to GenAI. I wanted to know whether LangChain is used in production ?

[@jamesbriggs]

Yeah I’ve seen it used, it typically won’t be the *only* thing and there’s often a lot of tweaking required, but it’s used in prod

[@dikshyakasaju7541]

I tried it with other models too but it didn't work as the documentation suggested this: Use with regular LLMs, not with chat models. Is it because Anthropic models are good at reasoning/writing XML?

[@jamesbriggs]

yeah they've been trained to do function calling / tool usage via XML tags - I find that comment in the docs odd, as they recommend using with Anthropic models, but Anthropic models at all chat LLMs afaik (maybe Claude 1 is not?) - but in any case, it works well!

Can we use XML Agents together with chain of thought prompting (ReAct)? If anyone has tried this out, please share your notebook -- much appreciated!

[@jamesbriggs]

I don't know about using over many iterations, but for single tool usage this has worked as a replacement of ReAct for me

[@Lampshadx]

you can just edit the prompt that you pass in create_xml_agent to use a ReAct style prompt. That's what I have been doing, otherwise, it often use the tool when it doesnt need to
