Trying to build a simple agent without the framework getting in the way. I keep hearing "just use LangChain tools" but the OpenAI function calling API seems more direct.
I'm price-sensitive. I need to know exactly what I'm paying for and have fine-grained control. LangChain's abstractions often hide the real cost and add steps I don't need.
Does using the native OpenAI functions give me more control and less overhead? Or does LangChain actually add necessary value here without bloat? Concrete examples would help.
