"""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 the LCEL based programs
to scale better for higher concurrent loads.
**Batch** operations allow for processing multiple inputs in parallel.
**Streaming** of intermediate outputs, as they're being generated, allows for
creating more responsive UX.
This module contains non-core Runnable classes.
