I've definitely got heartache here, and they merit criticism, but it is real We need a lot of pluggability to support diff vendor LLMs and BYO LLMs in Louie.ai, so having langchain has been nice for helping code to interfaces vs vendor lockin. It definitely has growing pains - ex: sync & multithreading is important for us so we are generally coding around langchain while that smooths out. Likewise, we ended up building much of our conversational and multitool capabilities as custom libraries vs using theirs for similar quality reasons. We can't use any of the codegen capabilities because they are massive security holes so doing our own work there too. If anyone is into that kind of work (backend, AI & web infra, ...), definitely hiring for core platform & cool customer projects here: louie.ai / Graphistry.com/careers
