Learn RAG From Scratch - Python AI Tutorial from a LangChain Engineer
Learn how to implement RAG (Retrieval Augmented Generation) from scratch, straight from a LangChain software engineer. This Python course teaches you how to use RAG to combine your own custom data with the power of Large Language Models (LLMs).
💻 Code: github.com/langchain-ai/rag-f...
If you're completely new to LangChain and want to learn about some fundamentals, check out our guide for beginners: www.freecodecamp.org/news/beg...

Assala mu alaikum brother
The complete happenstance of the phrase "do rag" sounding like "durag" coming from this video was awesome. Sorry, totally unrelated...but it made me chuckle.
Include more of langchain, llms, industry level based tutorials
This man is amazing!
This is great! Thank you so much!
Always a fan of a lance video
VERY WELL EXPLAINED. THANK YOU
Thank you!!!
thank you
Please let us know when the blog related to adaptive RAG will be uploaded, Lance mentioned that he will be uploading it in a day or so. Also I wanted to ask this question to general public, which one is better, State machines or Guardrails?? (In the context of creating complex flows using llms)
Thank you !
great content
Great!!
Awesome as always
This is great content. Speaking of that 95% of private data I guess a lot of practitioner are finding it hard to convince business people to share their data with an LLM provider. And of course concerns are very much understandable. I guess people would feel more comfortable if a RAG application would be able to clearly define a partition of data that it can work on for the benefit of the tool, and a partition that can be either used as obfuscated or simply never shared, not even by chance.

Maybe the solution would be running the model locally?

Love the teaching style! at 9:00 you mention that you've walked through the code previously. Is there another video to go with this one or did I miss something?

Amazing.
Question:. Is it possible to do RAG across different vector stores that use different embedding strategies?
❤❤❤
is it possible i can do rag and combine data with huggingface models?
What the name of this screen recorder used by Lance?
How to add coverstional memory to it?

And there was me thinking "how can it take over 2 hours to talk about applying RAG status to your project plans"

Hello, at 27:13 why is he using itemgetter to pass the question? What's the difference between doing that and setting a RunnablePassthrough() in there?
@flaviobrienza6081

No difference, just that with RunnablePassThrough() you don't need a dictionary in the invoke
Amazing videos but how does this translate into careers or jobs? What positions are employers looking for? Would they even hire anyone without experience? How do you even get started? I'm aware this channel mostly focuses on the coding and hands-on experience but I wish there was an actual channel focused on employment. I'm pretty sure there are channels out there and if anyone has recommendations, I'll be grateful.

Start working on some AI projects first, on your own, in your spare time. Show some results. Once you have two to show, getting a job should be easier. You don't actually need this langchain thing. As for how you get started, if you've already used GPT-4, etc., thinking about larger workflows that chain inputs and outputs in creative ways to solve problems. Also think about when you need to use embeddings for distance computation. You can use the LLM+embedding APIs directly or via an SDK, optionally sometimes with a local vector database. You don't need to go fancy.

This is the way...
Thanks for the excellent video! If your goal is to democratize gen AI to as diverse an audience as possible, I suggest you stop using OpenAI in these tutorials. In many parts of the world, having a credit card is not an option and OpenAI quickly backs you into that corner. Use, promote and support open-sources alternatives instead. Thank you.
This seems like it's going to pigeonhole me and tie my hands into a small dogmatic set of patterns, when what I need is broader freedom that I can accomplish without it.
Does this video have everyone brainwashed? If you know basic programming, you don't need langchain at all. I don't like unnecessary abstractions.

Yeah but the building blocks are useful. Do you write your own sorting functions?
