Relationship Graph

Source Code

"""LangChain **Runnable** and the **LangChain Expression Language (LCEL)**.

The LangChain Expression Language (LCEL) offers a declarative method to build
production-grade programs that harness the power of LLMs.

Programs created using LCEL and LangChain Runnables inherently support
synchronous, asynchronous, batch, and streaming operations.

Support for **async** allows servers hosting LCEL based programs to scale better
for higher concurrent loads.

**Streaming** of intermediate outputs as they're being generated allows for
creating more responsive UX.

This module contains schema and implementation of LangChain Runnables primitives.
