Building an app around a LLM, Rails + Python or just Python?

   Build LLM-powered applications in Ruby

   

   currently in the same boat as you at my company, we've been looking at Boxcars and LangchainRB as our gems but they're pretty new to the scene so not sure about that. I love the idea of langchain for the extensibility of it though - we used the ruby-openai gem for a while but it didn't do what we needed. I'll come back in a week or two with with what we decide (python microservice with flask served api endpoints vs ruby all the way)

   Calling Python functions from the Ruby language

   

   I have build a rails app that uses openai gem and it's working very well. For more advanced things I am exploring Pycall: https://github.com/mrkn/pycall.rb to call python functions. Don't have any experience though.
