LangChain is a powerful tool for making it easier to build applications that use large language models (LLMs). LLMs are a type of AI that can generate human-quality text, translate languages, write different types of creative content, and answer your questions in an informative way.
However, building applications with LLMs can be time-consuming and complex. It simplifies this process by providing a framework that allows developers to focus on their applications’ core functionalities.
It allows developers to easily connect their applications to multiple LLMs. This means that developers can choose the best LLM for a particular task without being locked into a single provider.
