LangChain vs. LlamaIndex - What Framework to use for RAG?

I am subscribing and turning on notifications because of how well you explain stuff in this video! Kuddos!

The best, always.

[@kakashisensie100]

Amazing video. It would be even better if you can compare agents in both frameworks.

[@M10n8]

Yep, love it. We need more Udemy courses! Best teacher ever.

[@codingcrashcourses8533]

Haha thank you. I am already thinking of a new course. Probably an advanced course. But not Sure about the way i want to Set it up

[@swiftmindai]

I suggest you do an advance course with a specific end to end use case or project like you do in real world (for eg. specific chatbot for retails or ecommerce or anything) that can be implemented in production with very minimum change. That will level up skill to professional level for many of us who follows you here. Coursera and some udemy as well offers similar which they call it capstone project if I'm not mistaken. But since most of us here are comfortable with the way you explain, I'll be the first one to purchase your course :)

[@codingcrashcourses8533]

@@swiftmindai I will probably make an advanced RAG course, since I already got a course on Prod with Azure. I don´t like to cover multiple complex areas in one course/video :)

Wow great tutorial thanks, love the breakdown an explanation. 😊

Hello, thank you so much for your comparison in the video! I also have a small request - could you possibly make a prompt engineering video tutorial for both LangChain and Llama-Index, especially the use of LCEL in LangChain?

[@codingcrashcourses8533]

One or the other :). I would rather make a Video ok LCEL

@@codingcrashcourses8533 great 👍

[@Roy-h2q]

felt like langchain are more straight forward , but ofcourse perhaps there are some value for how LlamaIndex are implemented

[@coderider3022]

This is a good video. Thank you.

[@timtensor6994]

Great video. Subbed. I have a question , recently i was trying RAG application for german language using mistral , llama cpp , chroma and local embedding . However i found out that using llama index i couldnt even retrieve any documents and returned no answer . Has it happened to you that it didnt recover any chunks so as to say ?

[@codingcrashcourses8533]

No - the standard is that your retrieve the top-k documents. You sure you indexed correctly? Normally you always retrieve documents, no matter what.

[@sanjayojha1]

2 questions. 1st: How is Hyastack compared to these two?, and 2nd: Which one is more asked in Job openings?

[@codingcrashcourses8533]

I tried Haystack and ditched it because it forced you to install the whole transformer stack. That was ~1 year ago. Regarding the second question: No idea about job markets.

[@sanjayojha1]

@@codingcrashcourses8533 I have tried their beta 2.0, so far it looks good.

[@yinxing418]

Switched to Haystack and never looked back. Repo is way easier for me to understand, and you can write your own components. Just compare all the frameworks yourself and see what makes sense.

[@gjsxnobody7534]

Very cool. But how can me make it “learn on the go”. Meaning if someone asks a specific question and there is no answer. Like where is the bathroom in the restaurant. How to setup your notify a human to help, and then to add that Q and A to the RAG or Langchain, and then how to rebuild the model so it knows?

[@codingcrashcourses8533]

It depends. Add a "contact human" and then probably collect the answers and index them again. There are many different ways to add upon that

[@DataMind-xd7xm]

@@codingcrashcourses8533 how about using a RLHF system from the feedbacks instead?

[@Pratikology]

Amazing content as always , can you make a video on RAPTOR, it is getting popular for long context llms as an soft alternative for RAG

[@codingcrashcourses8533]

Thanks for making me aware of that

[@skyblaze6687]

i dont want to use chromedb how can i avoid it i want to store it in json or pickle or something else

[@codingcrashcourses8533]

Use FAISS for that. FAISS allows you to pkl your vectorstore

[@tirthvora8591]

Langchain also has high level chains

[@codingcrashcourses8533]

Yes, but these legacy chains and the chain interface is not the default.

[@HypeDigitalyAI]

Very interesting video...we have just landed a big client that has thousand of documents. Would it be possible for you to help us with this project man, or at least offer your expertise on some consulting session ?

[@codingcrashcourses8533]

Thanks for the request, but I have to decline since I am not allowed to done any consulting related work in my side business.
