LangChain got its start before LLMs had robust conversational abilities and before the LLM providers had developer decent native APIs (heck, there was basically only OpenAI at that time). It was a bit DOA as a result. Even by last spring, I felt more comfortable just working with the OpenAI API than trying to learn LangChain’s particular way of doing things. Kudos to the LangChain folks for building what they built. They deserve some recognition for that. But, yes, I don’t think it’s been particularly helpful for quite some time.
