Building a RAG application using open-source models (Asking questions from a PDF using Llama2)

[@GaurangDave]

Oh please don't stop creating these videos, this is really helpful. Very detailed and well explained! Thank you so much for this!

[@berkbatuhangurhan708]

Came from X, this is an amazing and very detailed walk through. Thanks for explaining even the tiniest bits of everything. Highly recommend this.

[@Meetlimbani27]

Seriously, This is the Best Tutorial I have seen which explains everything by building it with scratch. I was searching for a good tutorial from scratch for around 15 days now. My search ends here

[@vadud3]

I went through tons of youtube videos and no one breaks down the process like this video. You will actually learn how python tools are used step by steps. This is the best video from my research. Thank you for making it available!!

[@TooyAshy-100]

Santiago, your videos on LLMs have been incredibly helpful! Thank you so much for sharing your expertise. I'm eager to see more of your content in the future.

[@anonymoustechnopath1138]

Thanks a lot Santiago!! Really needed these videos for LLMs. Keep them coming!

[@QuentinFennessy]

This is an excellent walk through - easy to follow and very practical

[@liuyan8066]

I like this fundamental courses, especially the last RAG one, I followed other training to build AI products, some teaching is over 10 hours. After i finished, I still didn't fully understand why I coded like that. Now these courses can make the connection step by step. Thank you.

[@lokeshsharma4177]

This is the BEST video ever made comparing all the LLMs performing same task. God Bless You

[@swatantrasohni5235]

Thanks Santiago for wonderful video..running LLM locally is something very handy for variety of task..Eventually everyone will have their own LLM running locally in device..thats the future..

[@yasirgamieldien]

This is an amazing video. Literally answered all the questions I had on building a RAG and it was really useful to see the comparison between GPT, Llama, and Mixtral

[@junaidali1853]

Lovely. Super useful video. I’ll be building a RAG system with a Vector Database and langchain for my freelance client for around $2,000 or more. Thanks Santiago for helping make my life better.

Thank you for the video! I found it particularly intriguing to consider the possibility of obtaining more accurate responses from the PDF using the Llama2 model. Given that local Language Models (LMs) tend to be highly sensitive to how queries are formatted, I believe it's crucial to refine your example further. Here are a couple of suggestions: 1) Instead of relying on a basic parser, it would be beneficial to prepare a set of predefined questions and answers. For instance, a question like "How much does the course cost?" could have a straightforward answer like "$400." 2) It's also important to determine the optimal format for prompts, specifically tailored for models like Mistral. By addressing these points, you could develop a truly functional product that delivers accurate responses. As it stands, most examples seem to demonstrate that local models struggle with practical applications and aren't quite ready for real-world deployment.

[@underfitted]

Great suggestions!

[@mehmetbakideniz]

hi. prompt engineering would definetely solve the problem of verbose answers but do you think it would also correct hallucinations as seen in the video?

Thanks Santiago! I am a student of your ML School course and I haven taken your course in two different cohorts. You ML School course is definitely the best of its kind in the market. Can you please design a new course on RAG that covers everything about this awesome technology including evaluation techniques and deployment? That will be wonderful and I cannot wait to enrol in your RAG (and any other AI) course!

Many Thanks for this video. I walked through the video, I was able to install Ollama3 on my machine, but I have nvidia GPU MX250, which is taking long time to answer the questions. it take 7 mins to answer two questions. I will watch your playlist of LLM.

[@GrantNaylor-b8l]

More great content. Clear, easy to follow. I have a question. If you only wanted a simple RAG to answer questions from small snippets of text (a few pages not 100's) would a vector memory store really be a bad thing?

[@energyexecs]

I collect old vintage engineering and science books from old bookstores that are ready to be junked - hopefully they are not copyrighted. 😊 My goal is to somehow convert these old books to digital then embed in a vector database. Then take them through transformer and layers and semantic to a LLM of some time for search by "natural language". I created an Independent Private Library Association on Facebook so my thought is to use Meta Llama as my LLM - I probably need to ask Meta Llama people for the costs to do this. It's just a hobby of mine. I have lots of old books. And now Libraries are trashing beautiful old vintage books. I want to do all modalities because these books have beautiful lithograph sketches and single line drawings - I think you've seen such books.

excellent work! so clear and concise..

[@TheMunishk]

Congrats and well done for producing this useful content. Exactly what I was looking to kick start my langchain journey with the models. Let me practice this but I was also looking for how to integrate all this in the front end. Do you have a video of which tools to build a front end for the prompt that will interact with the backend LLMs?

[@alextiger548]

Ma, thanks for what you are doing! Fantastic stuff.

[@GEORGE.M.M]

Hi there! I'm new to AI and RAG systems and have spent the past few days diving into your tutorial to understand each step and debug along the way. I have to say, THIS IS A GREAT TUTORIAL! I do have a question about alternative local LLM approaches. Regarding the accuracy of asking questions and retrieving relevant information from PDF documents like research papers and books using local models, would you recommend this approach over using tools like Ollama UI and LM Studio? Are there specific advantages or disadvantages to consider when choosing between these methods?

[@ravindarmadishetty736]

It's such a fantastic video, Santiago. 🎉

[@asnair]

Excellent! What about the last step -- saving the vector embeddings in the pinecone database?

[@joeldartez829]

Truly, you're the best. I've never met someone who explains things so well. I apologize if it is written somewhere and I missed it, but I wanted to ask if I buy your course today, can I have access to the past content today? I don't want to wait until the live sessions in April (or I want to arrive prepared for them). Thank you very much.

Looking for these videos, next i am looking a model to train on SQL data

[@mehmetbakideniz]

this was super helpfull. I noticed that using m2 pro some cells took 16 seconds in my laptop while it just took 0.5 second in your computer. then you said you are using m3gpu. How can I make sure that I am using gpu instead of cpu in executing this code? or does langchain already utilize gpu when needed?

[@fintech1378]

is searching via embedding always better compared to 'traditional' search aka very long context window? where should we use one or the other..how bout if we wanna build multimodal video recommendation system

[@TomasTrenor]

Amazing video Santiago ! Many thanks . Just tried it with Llama3 8b and, as it seems , is not so accurate as Llama2 ( what does not make sense obviously). I need to deep into it

[@azharsham]

Brilliant video! but one quick question , are you passing the same string to both question and context here ? If yes does it always work in case of document reader

[@AntoineToussaint]

Great videos by the way, started with the "Build from scratch" one. Quick question though: why does the embeddings for the RAG need to match the model type? My understanding is we only need to be consistent on the question embedding and the store embedding for similarities but then the retriever pulls the actual documents and send then to the model. Later in the video, you say you can use any retriever , like Google search or anything so it seems to me the embeddings can be anything as long as question and documents embedding are the same.

[@underfitted]

They don’t. That was my mistake. You only need to make sure the embedding you do on the query matches the embedding you used when processing the data. But you can use any embedding model regardless of the embedding used by the LLM.

[@AntoineToussaint]

@@underfitted Thank you for the prompt -- pun intended -- reply! I watched two videos and now I am running ollama! You explain so well and give a lot of passion for these. I am trying to build a simple model so I can take a query and extract some custom filtering to send OpenSearch. Great stuff. Thank you for making these videos!

[@TexttoInvoice]

This video is awesome so so great!!! Thank you so much for such a quality video. Question: what’s the best way to improve the results being accurate to the document, can using structured data such as spreadsheets and CSV files give you a more accurate answer and maybe the model prefers interacting with them? Also, if there was more instances of the data, say multiple different documents, containing the same information that needs to reference ? Anyone who has found the best way to optimize getting correct answers from your retrieval. Please let me know! Thanks

[@gilbertoparra5255]

Thank you for the content very helpful, I have one question, how do I know it is running locally? I mean for every model we used the langchain library as if it were consulted through the API.

[@underfitted]

They are running locally because I’m using Ollama to host the models in my computer. We use Langchain exactly as we would use it to access online models. That’s good. It means we can switch models without changing the code.

[@theDrewDag]

Is it actually true that you need models to be aligned with their respective embeddings? I don't think so 🤔 Embeddings are used only for the vector search and lookup functionality. At the end of the day all the model is seeing is your textual prompt. You can use OpenAI embeddings with any open source models and viceversa.

[@underfitted]

You are right. In this example I only use the embeddings for the search, so what I said is irrelevant here.
