Lot of Langchain grudges in this thread, feel the need to counterbalance by adding: 1. This domain is moving very fast 2. Creating a wrapper around a fast-moving domain is difficult, lots of thrash on design patterns 3. Langchain's out of the box examples have undoubtedly made it easier to grok LLM patterns That being said -- this article is about building a production-ready LLM app, and currently I strictly treat Langchain as a learning aide. Ultimately I'm glad Langchain exists, and I hope to see Harrison et. al. bring more improvements to the underlying abstractions. Possibly with a more functional inspiration?
