The Definitive Guide to Tool Support in LangChain4J

[@msrgopinathn]

Nice intro to what LangChain4j is capable of doing.

[@talesfromthejarside]

Thanks :)

Great show, Ken! How did you get the DEBUG: lines to print?

[@talesfromthejarside]

Thanks! I have a file called logback.xml in my src/main/resources directory, and in that file the level of "root" is set to "debug". That's mostly useful when you turn on logging in a chat model, but here it turned out to be convenient anyway. Clearly I need to add my repo to GitHub, which I'll do after I've cleaned up a few things. Thanks for commenting!

Fantastic! a question related to Data ingestion, do you have something or a link that is talking about ingesting and manipulating tabular data from csv, excel or that type of sources?

[@Talaria.School]

Thanks a lot, for the content.

[@talesfromthejarside]

Glad you liked it

Does langchain4j handles token limit for model if function call responds tokens > limit ?

[@talesfromthejarside]

I don't think it does anything other than whatever the underlying AI tool does. Most of them don't handle that well either. But token limits keep going up and up, so maybe that won't be a serious problem for you

[@NIKHILDUBEY19031993]

does it work with demo api key provided by langchain4j?

[@talesfromthejarside]

It should, but I have my own key so I didn't try their demo key. Good luck!

[@NIKHILDUBEY19031993]

@@talesfromthejarside I have been trying out with demo key. It works except that it doesn't execute any of the tools. If you could confirm, it would be really helpful.

[@talesfromthejarside]

That's very strange. I'll see what I can do. You should be aware, however, that LangChain4j has a Discord server at discord.com/invite/JzTFvyjG6R . I'm somebody there will know the answer right away

[@pandeyZee]

Can you please create a vedio about how to use function in langchain4j usimg gpt4

[@talesfromthejarside]

"Tool support" and "function calling" are two terms that mean the same thing. Check the OpenAI docs and you'll see them used interchangeably. I'm LangChain4j, you use the @Tool annotation to indicate which "function" (i.e., method) inside a class you want the AI to call. In other words, you already found the right video :⁠-⁠)

[@erryj3707]

good

Thanks 😊
