description Overview
LangChain Expression Language (LCEL)
LCEL is not a full agent builder but rather the foundational, modern way to compose LLM calls, prompt templates, and output parsers within the LangChain ecosystem. Its strength lies in its explicit, declarative nature, making complex chains predictable, testable, and highly optimized for performance. It is the recommended building block for anyone using LangChain to ensure reliable, structured out...
