"We used langchain framework both for it's library agnostic methods for various AI platforms, as well as various helpers such as document parsers, chunking utilities, e.t.c. Moreover it has great agentic development support with langgraph.
As an alternative we could have used OpenAI APIs directly however due to its fast changing nature, and also because we don't plan to depend on it long-term, it was better to go with langchain."
