Understanding LangChain and LangTest: Use Cases and AWS Implementation

What is LangChain?

LangChain is an open-source framework designed to help developers build applications powered by Large Language Models (LLMs). It provides tools to manage LLM calls, chain multiple LLM prompts, and integrate with various external data sources. LangChain is widely used for chatbots, question-answering systems, summarization tools, and more.

What is LangTest?

LangTest is an automated framework for testing language models to evaluate their accuracy, bias, and robustness. It ensures that LLM-powered applications function correctly by running systematic tests across different parameters, making it an essential tool for AI-driven applications.
