Using an LLM in isolation is fine for some simple applications, but many more complex ones require chaining LLMs - either with each other or with other experts. LangChain provides a standard interface for Chains, as well as some common implementations of chains for ease of use.

The following sections of documentation are provided:

  • Getting Started: A getting started guide for chains, to get you up and running quickly.

  • How-To Guides: A collection of how-to guides. These highlight how to use various types of chains.

  • Reference: API reference documentation for all Chain classes.
