Support for OpenAPI

[cpursley]

Something similar to: https://python.langchain.com/docs/integrations/toolkits/openapi

Just learned about this approach here: https://learn.deeplearning.ai/courses/functions-tools-agents-langchain/lesson/6/tools-and-routing

Yes, the Elixir LangChain library already has functions (the only type of tool that exists for OpenAI). I created a LangChain.Function and LangChain.FunctionParam for defining the tools. I'm working on better explicit support for the "tool" concept though. OpenAI changed their API to be more centered around "tools" instead of functions. See here: #48

There's an example of a pre-built tool here: LangChain.Tools.Calculator.

There's an example of a router here: LangChain.Chains.RoutingChain

As for OpenAPI, I'm not aware of a good Elixir library for creating an OpenAPI client. Do you know one?

Yeah, the existing routing and tools are awesome. I was thinking specifically for utilizing OpenAPI compatible APIs like this: https://medium.com/@jedrzejplucinski/4-steps-to-create-chat-bot-for-your-api-e563c897ef85

Not sure about specific clients, I'll look into it.
