You basically don't use langchain for anything besides 30 minute demos that you copied from someone else's github. It has a completely spaghettified API, is not performant, and forces you into excessive mental contortions to reason about otherwise simple tasks.
LlamaIndex is pretty good.
- monkeydust 3y agoYea discovered this with Langchain last week. Was great for a demo then started to push it harder and spent ages trawling Reddit, discord, GitHub trying to find solutions to issues only to discover what was supposed to be supported was deprecated. Got a massive headache for what should have been a simple change. Moved on now.
- sophiabits 3y agoYeah +1 We originally started out building features with LangChain (loading chains from YAML sounded good—it felt like it would be easy to get non-engineers to help with prompt development) but in practice it’s just way too complicated. Nice idea, but the execution feels lacking. It also doesn’t help that LangChain is evolving so rapidly. When we first started using it a lot of code samples on the internet couldn’t be copy/pasted because of import paths changing, and at one point we had to bump by ~60 patch versions to get a bug fix, which was painful because it broke all kinds of stuff
