Love how you are sharing your processes and really approaching it from such an accessible level. I learned a ton and I'm having so much fun diving into LangChain. Thank you for these awesome videos and your channel growth is well deserved. 🎉

[SonAyoD]

Very interested in the full bot tutorial. This transition to AI is nuts! Programming will never be the same

[reallions]

Hope you create more videos on Langchain with JS

I do hope you expand on this topic, I love to know how to setup a code / documentation bot.
Working as an IT Engineer I would find this incredibly useful.
- Powershell / MS Azure / Exchange - Would be my pairing.

As I want to use langchain and GPT 4 with my own large business information to be able to ask questions on the information, how can i make sure its 100% secured, i cant just load my business client data to GPT or cloud as i sign confidentiality with them, how you go about it ? do i need to install bloom like model? but GPT 4 is best experience.

Loved your teaching style. Thanks for sharing.

If I want to get data from API call (typescript) and the run some stat QAs like min or max value or total count on a specific day, what would be the ideal data structure? Dataframe, SQL or anything else?

[DannyPeck]

What's your shortcut so `repo` opens the repo of the codebase you're in? super handy!

[juanmazzu]

Is someone having this same error runing the code?
ReferenceError: Headers is not defined

[fernandodiaz]

The didactic explanation that you provided was very good. To implement this solution in the cloud, what is the hosting service with NODE support that you recommend?

[DavideRuggeroBrambilla]

Hey thank you for your contents!! I tried to do the same but when I run: npm run dev
I have the following error:
Request failed with status code 429.

I was wondering if you have a free plan on openai or not cause I made a test api project and the api seems working so I thought is weird, it might already be hitting the limit of api requests with this?

[paulwilde]

confused on the environment file, where do I open the file and add the API key? what's the terminal you are typing in? thanks

[damonwu]

Nice video, thanks for sharing man 👍, may I ask how can I get the typewriter effect? Really like to know if you don't mind ~

[norikorebolledo]

Hi, thanks for this video, I learned a lot. I'm just curious, the icon you used in your chat is nice, where did you get it?

[ronl]

can you explain if for building my own business knowledge base, is better to use openAI embedding or fine tune and difference?

[AC-sjhu]

One question, to do all of this stuff, we need to have Funds in our openAI account ? I was thinking we can use chatgpt 3.5 and use it for free....

[mushroomthump]

Hey, great video! Just curious if you have noticed any downsides to implementing Langchain with JS over Python. Are you only using it with JS because you already knew JS or is there another reason to choose it over Python? Thanks!

[oliviervincent]

Part 2? Not able to locate it. Is it out yet?

[simonk]

I love how your vscode looks! What theme are u using? Also what’s the extension for highlighting the whole function with that bright line?

[DonjiKong]

Do you recommend learning JavaScript or Python if I want to start building with langchain? My 5 month goal is to become a langchain expert

[wdampier]

Nice video! I would love to know how did you get all documentation from nextjs and pass it to langchain.
