What is Langchain.rb?
Langchain.rb is a free, open-source Ruby gem for building applications powered by large language models. It gives Ruby and Rails developers one interface for many LLM providers, plus vector search, retrieval-augmented generation and tool-using assistants, so you can add AI features without wiring each API by hand.
