90% (or more) of tech tutorials start with code, without providing a conceptual overview, as you have done. This video is phenomenal...
Appreciate it! 🙏 Thanks for watching
Totally agree with this. I love the way this guy teaching the conceptual
I've noticed a significant lack of comprehensive resources that cover LangChain thoroughly. Your work on the subject is highly valued. Thank you
Yes, there's not enough books on it. The documentation is sparse
Agreed. This was the perfect introduction, for me at this time, to Lang chain.
This is the best 101 video I found on the subject. Most of the other videos assume you're already somewhat familiar with the tools or aren't that beginner friendly.
Your video really helps understand the basics of langchain and provides a good context as well. I'm looking forward to more such videos !
With immediate effect I have subscribe to your awesome channel.
Explanation to LangChain was clear and concise. I really learnt a lot in just 12 minutes.
This was an awesome and very straightforward video. I believe that it's the most useful video about LangChain that exists I've seen so far. Even people that don't know much about programming can follow. Thanks so much!
Thank you for the video. I think it gives a really good introduction to the topic without much distraction. Absolutely pleasant to follow even for a non-native speaker.
Wow, this video on lang-chain have all the pieces i have been searching for.
Thank you so much for taking time and making this awesome video.
One of the best QuickStart streaming that I've seen. A clearly explanation in combination with images. Many thanks.
Thank you! 🙏
I've been watching a lot of AI videos, this is definitely one the best - well-organized and very clear
solid instructor. good intro langchain at the right level of depth. For as quick as he rips thru a huge amount of information, he is still pretty easy to follow.
Having read through the LangChain's conceptual documentation, I must say this video is a great accompaniment. Very clear and well presented and for a non coder like myself, easy to understand. (I'd pay for a LangChain manual for 5 year olds!) . Subscribed.
Thank you! 🙏 Glad it was helpful

Thank you. I have watched a lot of videos that attempt to explain LLM's and LangChain as successfully as you have here but fail to do it as succinctly as you have. I was looking for a video that I can share with my clients that explains what LLM's and LangChain are without being too dumbed down or being too 'over their heads' and this video is perfect for that! So, again - thank you.
Glad it was helpful! I really appreciate the comment, thank you very much 🙏
Excellent intro, especially for an experienced programmer to start using after a single watch. Learned a lot in a short time with it. Thanks for making.
You're welcome! Thanks for watching
I have been searching and searching for an explanation of how to do this exact thing!! Yasssssss thank yooouuu! ❤
Thank you so much for covering all the components in just 13 mins. Though, it took an hour to learn and absorb everything :D
I found this to be very comprehensive and indeed useful.

Fantastic overview of Langchain! Thank you @Rabbitmetrics
This is gold! Thank you!❤
EXCELLENT OVERVIEW: Pls note Pinecone as of 1 week is NOT allowing new, free accounts to do any operations! PLS CONSIDER DOING SIMILAR VID FOSS end to end, There is a lot of interest. THANK YOU
What a beautiful video. You Sir are a great teacher ! Thank You !
Thank you!
Thank you very much for the video! Really helpfull to kickstart with LangChain
Glad it was helpful!
The coolest thing about enhancing LLMs like this is that locally-runnable models will be very interesting (no huge API call costs) and smarter than by default.
I would love local LLMs! Though I doubt that one advanced as GTP-3.5/4 will be able to be run locally for a few years because of the required computational power. I still look forward to the day that it becomes a thing though!
The costs are not the advantage. Hosting things on your own hardware is usually more expensive, especially if you need multiple models(embedding model, LLM, maybe a text to speech). The advantage I see is that you could use custom models trained on your data

Excellent introduction! Thanks a lot :-)
Thank you this is the info I was looking for.
👍 Your explanation is so structure and clear. I can understand how langchain works now even though I don’t know your python codes at all.
Thanks! 🙏 Glad it was helpful
Excellent overview - Thanks!
You're welcome, thanks for watching!
Excellent intro. Harrison would approve!

Fascinating. Thank you for this.
Awesome work thanks a lot!
just found your channel. Excellent Content - another sub for you sir!
Thank you I appreciate the support!
Great video! Thank you.
Thanks! This is the best high level langchain video I have watched. Im not a programmer but this overview is invaluable...its clearly explained and demystified the dark arts of langchain 😂😂...question, whats the most straightforward way of converting website data into vectors? Is there some way to scrape urls...looking to create simple q&a agents for small websites...thanks
I’m glad it was helpful, I appreciate the comment! Regarding scraping urls, take a look at the latest video I’ve uploaded th-cam.com/video/I-beHln9Gus/w-d-xo.html In that video I’m using LangChain’s integration with Apify to extract content from my own webpage
@@rabbitmetrics thanks. Yes took a look. Will see what I can do. Came across Apify in my research yesterday
! Will try to run this with llamaindex ….Im teaching myself! There’s not many apify videos around so thanks
Thanks for sharing the knowledge 👍
this video was nice and gives a good intro to the topic
super helpful. I think langchain engineer could hold significant value in the current job market
I agree!
Great explanation, thanks!
Wonderful video. Thanks.
Brilliant. Structured and clear.
Thank you!
This is really great video!
Great!!! Fantastic! Awesome! Thank you for sharing!
Thanks for watching!
This was so helpful! What are your thoughts on connecting langchain and flutterflow?
great! I can use this video to teach my friend
Your explanation is super clear to understand for me as a beginner. I want to know brief steps for the code flow as titles just like
1.Creating environment to get keys, 2. etc.,. Can anyone answer it?
This is excellent - I have a question re the splitting, lets imagine you have email templates that average like 2000 tokens a piece or IG captions with like 500 tokens - should things like this be embedded as one chunk or what is the advantage to splitting up into say 100 token splits?
🎉🎉🎉 Great overview of LangChain, can you do similar video on using LangChain on open_assistant and weiviate vector database
Thanks! That’s a good idea for a video
great overview and slides
Thanks friend. You answered a lot of questions here and the repo, helped understanding your presentation much better. Please share more. Have a great day.
You're welcome! Thanks for watching
How is the relevant info (as a vector representation) and question (as a vector representation) combined as a prompt to query the LLM? The example you show is a standard ChatGPT textual prompting scenario. The LLM will spit out what it knows and not what it does not know. So what application will this info be useful for? Also is there any associated paper or benchmark that investigates the performance of extracting "relevant information" using this chunking method or is it implementing some DL based Q/A paper?
Excellent work!
amazing tutorial. thank you. you are amazing
Hi there, is there a way to combine steps 4 and 5? I assumed you would be using the Agent to answer questions on the autoencoder that we had focused on for the whole video, but then we just used it to do some maths. I think it would be useful if it could answer questions based on the embeddings we have in our index?
Great explanatory video! Would you provide a link to this Jypter notebook?
Great video! Do you know if pinecone works with other languages? For example to store and then retrieve?
Highly appreciated video
Great video clear and simple. I wonder is it were possible how can we use this with azure OpenAI
Great explanation!
Thanks a lot. Very good explanation.
Thanks!
Awesome Explanation
Great. Would love to have access to the code as well. Thanks!
thank you a lot, really helped
Impressive video, thanks! I will subscribe to your channel!
Your summary of LangChain is very accurate. Do you have a PPT to share?
Thanks! Unfortunately, I don’t have a PPT. The video is made with FCPX
Great video, what is the first app that you were using to explain the diagram ?
I inspected Langchain code as soon as it was released, ran some tests and never used it since. Im surprised so many consider its limitations acceptable. Using embedding similarity as a query filter is like trying to answer a prompt by comparing every chunk of text to your prompt. It makes absolutely no sense because often times an answer looks nothing like a question, and/or the data needed to answer a question looks nothing like the question.
The purpose of the embedding layer in a transformer neural network is to prepare the prompt tensor for further processing through the remaining model layers. It’s like bringing your prompt to the starting line of a long process to be answered, but instead of bringing just the prompt to the starting line, langchain brings the entire text your asking the question of to the starting line with your question and asking them to look at each other and be like “hey, whoever looks like me, stand over here with me. Ok now the rest of you go away and I’m going to ask chatgpt to see which of you remaining can help answer me”.
This is a slight of hand trick, trying to replace everything that happens after the starting line, with chatgpt, but it doesn’t really work for 2 big reasons: (1) chatgpt context is not large enough to transform both the entire text your asking a question of + your prompt, and the same limitation applies to batching (2) your embeddings are incomplete because they were not created by the network, but simply hacking the first layer in a sense
Interesting take. I suspect most people don't understand the technology enough to see how it works. Would be helpful if you could make a video explanation
Biggest limitation right know that we can’t get over with, is chat GPTs context length, there is no way around that unless the contexts is greatly increase by OpenAI themselves or we could train our gpt4 model on large texts
@@albertocambronero1326 I agree. It would cool if there was a sort of "short term memory model" that could hold personal data. I don't see expanding context length as a parsimonious solution. Model queries produce the best results when they are sort and poignant. Any time you need to bring a ton of context to the prompt it reduces the relative weight of the primary question. Imagine a patient friend who accepts questions with an unrestricted context length. They have never read the book Great Gadsby (i.e. this would be like your personal data) - so to ask them a question about Jay Gatsby the question must begin by reading them the entire Great Gatsby novel, followed by "thee end... Where did Jay Gatsby go to college?" Then to ask them another Gatsby question it requires reading them the novel, again, and again. It would be awesome if there was a way to side-load a small personalized model that can plug into a LLM for extended capabilities.
@@dendrites amazing response, I did not know what was going on under the scenes with the context and did not know model queries produce the best results when they are sort and poignant.
I believe that if you send the novel it would be stored in the context of the model and then you would be able multiple questions (?) or would the novel be lossing importance (weight) as more and more contexts is added?
Referring to the comment that started this thread, the complicated bit about training the model on a certain topic, lets say: we train the existing GPT4 model in the book Great Gadsby it would probably know how to answer questions about the book, but it could not analize the whole book to find linguistic trends in the book (like what is the most talked about topic in the book) unless you ALSO feed the model with an article about "the most talked topic in the book".
I mean I want my GPT4 model to read the book and analize the whole picture of what the book is about without needing extra articles about the book.
(my use case is to make GPT4 analyze thousands of reviews and answer questions about it, but right now using NLP techniques sounds like a more duable option right now or at least until we have an option to extend GPT4 knowledge)
You can't say simply "it doesn't really work". It really depends on the use case. There are true limitations and some creativity might be required to leverage it. The context size might me sufficient for smaller use cases or it might be sufficient to break down bigger questions into smaller questions with their own contexts and then summarize etc.
Hi, this video is one of the best, but now langchain changed its modules and classes, please update us with the new video, for eg: simplesequentialchain is not supporting now!!
Excellent unpack! Can you please provide a link to this notebook?
Bloody brilliant!
How do you store a API key in the .env ? I created the .env file in the root and I get error 500 when trying to open the .env and even chatgpt doesn't know why.
Really good video!
Great job, what is the soft that you use to draw these magic things?
so well explained! :)
Thanks!
very nice
thank you
that's so amazing !!!
great video !
