LangChain Explained in 13 Minutes | QuickStart Tutorial for Beginners

[@imtanuki4106]

90% (or more) of tech tutorials start with code, without providing a conceptual overview, as you have done. This video is phenomenal...

[@rabbitmetrics]

Appreciate it! 🙏 Thanks for watching

[@ThangTran-hi3es]

Totally agree with this. I love the way this guy teaching the conceptual

[@PatchworxStudios]

I disagree. I almost never find good code examples instead only concepts for dummys.

[@adamgkruger]

I've noticed a significant lack of comprehensive resources that cover LangChain thoroughly. Your work on the subject is highly valued. Thank you

[@artic4873]

Yes, there's not enough books on it. The documentation is sparse

[@andrewflewelling4294]

Agreed. This was the perfect introduction, for me at this time, to Lang chain.

[@HarshGupta-sf4rj]

I never comment on any video but your flawless explanation made me, Thank you for such a masterpiece.

[@rabbitmetrics]

Appreciate the kind words! 🙏 Thanks for watching

[@zerorusher]

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.

[@guitarcrax127]

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.

[@rabbitmetrics]

You're welcome! Thanks for watching

[@jayhu6075]

One of the best QuickStart streaming that I've seen. A clearly explanation in combination with images. Many thanks.

[@rabbitmetrics]

Thank you! 🙏

[@sitedev]

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.

[@rabbitmetrics]

Glad it was helpful! I really appreciate the comment, thank you very much 🙏

[@danquixote6072]

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.

We need more videos like this, comprehensive for the general public and for newbies like me. Thank you!

[@manrajsingh8617]

Best video I have ever seen on explaining Langchain soo far 💯

[@steve_wk]

I've been watching a lot of AI videos, this is definitely one the best - well-organized and very clear

[@AmeliaHoskins]

Good introduction for people with no AI nor code knowledge the steps can be abstractly understood. The names of elements given some understanding.

[@ZorroS-b9z]

Thank you. Information is presented really well for a 5 year old like me

[@anandakumar31]

Excellent video for beginners who want to start on Langchain. Well explained.

[@rabbitmetrics]

Thanks! Glad it was useful

[@maya-akim]

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!

[@chukypedro818]

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.

[@ranjithpals]

Your video really helps understand the basics of langchain and provides a good context as well. I'm looking forward to more such videos !

[@GeoAIGREL]

One of the best 101 video on LangChain out there, Kudos to you!

[@postnetworkacademy]

"Great video! This explanation of LangChain's core concepts is super helpful for beginners looking to build LLM applications. Thanks for sharing the code link as well-makes it easy to follow along and experiment!"

[@garratygarret8559]

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.

[@4.0.4]

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.

[@ignfishiv]

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!

[@Ltsoftware3139]

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

Thank you very much, Rabbitmetrics! This tutorial is absolutely a gem for someone looking for a clear and concise overview of the main concepts!

[@rabbitmetrics]

Thank you! I'm glad it was helpful

[@daffertube]

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.

[@rakeshmr3329]

Really fantastic crisp explanation of LLM nothing more nothing less.

[@rabbitmetrics]

Thank you!

[@nickfergis1425]

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.

[@Thisnthat979]

Hi I am new to Python, how do I get to the screen at 5:00 to edit the environment file? I installed all the component then stuck, thank you!

[@Janeilliams]

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.

[@mnava4290]

Excellent coding examples. Please do more of these. Please do a tutorial on how to summarise comments received on a KZbin video.

[@dudefromsa]

I found this to be very comprehensive and indeed useful.

[@ejclearwater]

I have been searching and searching for an explanation of how to do this exact thing!! Yasssssss thank yooouuu! ❤

[@ernikitamalviya]

Thank you so much for covering all the components in just 13 mins. Though, it took an hour to learn and absorb everything :D

[@repairstudio4940]

This is a absolutely wonderfuk video on LangChain and its clear and concise. Coukd you do a tutorial for beginners??? 🙏🏼

[@johnshaff]

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

[@MeatCatCheesyBlaster]

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

[@albertocambronero1326]

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

[@langmod]

@@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.

[@albertocambronero1326]

​@@langmod 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)

[@ugaaga198]

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.

[@PhoebePhuu]

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?

Zero clutter. A Guru (remover of darkness) is one who can create chunks of knowledge in a sequence that is easier for the Shishya (student) to learn with ease and get it to their neocortex without having to decode the vectors, that allows for carrying it to their multiple incarnations. Thank you Guru-ji.

[@rabbitmetrics]

I appreciate the comment - thanks for watching!

[@sujoyroy3157]

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?

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?

[@conne637]

Can someone explain to me, how the question & and the relevant (personal) data is combined when promting the model? Also, if I understand this correctly, using LangChain after all would enlarge the promt and hence number of tokens needed / cost? Thanks in advance!

[@thebluriam]

If you look at openAI's privacy policy, you'll find that they explicitly state that data provided through the API is not recycled into the training data for OpenAI's systems unless you explicitly enable it, it's off by default. So yes, you can use OpenAI's systems through the API with proprietary information and it wont end up in the training data. A quick search will let you find their official announcements about this.

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?
