Enjoyed this thoroughly because I'm a newcomer to code and want to take this model apply to certain things like industry specifications for Quality Engineers in Aerospace asking their chatbots about material specifications or generating purchase orders etc...endless workflow improvements on the horizon!

thanks for providing a useful lesson. it will be great to update by pinecone for the "langchain/vectorstores" has been deprecated.

This is an amazing video! The content is really really helpful for someone looking for a js based solution amidst all the python ones. Again, appreciate it.

This was the best class I've ever taken. I got a lot out of it. Thank you.

I do have one question.
If I wanted to add a CheerioWebBaseLoader() in the following code, how would I modify it?

async readFiles() {
const loader = new DirectoryLoader(this.dataPath, {
'.txt': (path) => new TextLoader(path),
'.pdf': (path) => new PDFLoader(path),
});

const docs = await loader.load();

return docs;
}

Thanks so much!!! Very illustrative video. Please go ahead with more videos for nodejs and js.

That was a clear explanation, thanks for uploading! peace.

Perfect job sir. Just one question. Where did you config the Openai_key?

[RenSap-vy]

Awesome tutorial, could imagine these video are part of a course.

Super super useful, thank you! Great job explaining it too.

Firstly, thank you for great content, delivered in very succinct and easy to digest way.
I was wondering if you looked at ways of updating documents in existing index as well as updating existing index with additional documents? From what I'm seeing at the moment it seems that the index might need to be recreated each time. I did find some information on using other vector storage solutions with suggestions of removing existing documents from the index first, and then adding the updated docs. Is this something you looked at?

You're videos are really good man. Thank you!

[mikerobin]

Thanks for this video, I implemented this in a project but the cost to the OPENAI API is really high

[andrewlewin]

Very useful, I can put this to practical use very quickly 😊

Is this Be A Better Dev’s alternative channel?

Why are you concatenating all the docs before passing them to the LLM? Could you please explain the reason behind that decision instead of passing them directly to GTP? By doing this, as far as I understand, you are losing all the metadata attached to the doc.

Thanks for the great course.

Can I use OpenAIChat instead of OpenAI to get answers inside a PDF document? If so, how can I modify it?
