LangChain is driven by a few core beliefs:

  • Large Language Models (LLMs) are great, powerful new technology.
  • LLMs are even better when you combine them with external sources of data.
  • LLMs will transform what the applications of the future look like. Specifically, the applications of the future will look more and more agentic.
  • It is still very early on in that transformation.
  • While it’s easy to build a prototype of those agentic applications, it’s still really hard to build agents that are reliable enough to put into production.
