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.

[@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.

[@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!!

[@anonymoustechnopath1138]

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

[@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..

[@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.

[@QuentinFennessy]

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

[@surygarcia6823]

This is easily the best RAG video out there

[@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

[@sarash5061]

This was just Amazing, You are a Star. Thanks for all the effort.

[@lokeshsharma4177]

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

[@geethikaisurusampath]

This is really Helpful. Specially the explainations behind why do it. Keep up the good work. Respect to you man.

[@MarkoKhomytsya]

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?

[@MarkoKhomytsya]

good question @@mehmetbakideniz ! I would like to know answer too!

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?

[@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?

[@researchpaper7440]

[@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?

This video is supposed to have a link to ANOTHER "from scratch" video as a popup - but WHEN that link pops up, I think it's ACTUALLY a link within this video pointing in a circular loop BACK TO THIS VIDEO, instead of the "pointing elsewhere" link to the other video it's supposed to be. (This video has a link to itself, if I didn't get MY wires crossed.)

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?

[@MD.IKRAMULHOQUE-c3o]

Can anyone clear the concept how the locally hosted Ollama model is connected to the program? i can see we are using OPEAI KEY. So got confused

[@fredericv3497]

Really good job and clear tutorial ! Thank you

[@surygarcia6823]

Is there any tutorial for making our own vector database for production?

[@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!

[@TomasTrenor]

[@underfitted]

Yes, you get immediate access to everything from day 1.

[@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

[@jpagano569]

Hmm is there a way to run this in CoLab or Github Codespace? I suppose the point is to run locally, but I hate setting up dev environments (because I'm new to coding!)

Great video 👏👏Really helpfull , can you tell which model mac do u have,I have a m2 mac 8gb -i am doubtfull i will be able to run these powerfull models.

[@Jonathan-ru9zl]

Great! Can this model and setup serve as an assistant to, lets say, a board design engineer that have thousands of components specs in pdf files? To find and analyze the components faster?

[@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.

[@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.

[@KumR]

Can u also pl add an UI using streamlit

[@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

[@alexstele5315]

[@basantsingh6404]

if you are using open_ai key, it means you are paying to use the open ai model. how is it open source ?

[@Hizar_127]

i want to deploy it on cloud. does it is possible?

[@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.
