For us LangChain actually caused more problems than it solved. We had a system in production which after working fine a few weeks suddenly started experiencing frequent failures (more than 30% of requests). On digging it seems that LangChain sets a default timeout of 60 seconds for every requests. And this behaviour isn't documented! Such spurious decisions made by LangChain are everywhere, and will all eventually come back to bite. In the end we replaced everything with vanilla request clients. Definitely not recommended to build a system on a library that provides very limited value while hiding a huge amount of details and decisions from you.
