In Agents, a language model is used as a reasoning engine to Let’s build a simple agent in LangChain to help us understand some of the foundational concepts and building blocks for how agents work there. This means that code in langchain should not by default instantiate any specific chat models, llms, embedding models, vectorstores etc; instead, the user will be required to specify those explicitly. For this LangChain provides the concept of toolkits - groups of around 3-5 tools needed to accomplish specific objectives. The Amadeus client. For conceptual explanations see the Conceptual guide.
